Today I’m going to show you the best bushmaster XM15-E2s accessories on the market today.

In fact:

I’ve hand-tested over 10 XM-15 accessories alone for this review.

The best part?

I’ve sorted them by use. So whether you need an optic or a buttpad, you’ll find it here.

Let’s get started!

The 4 Best Bushmaster XM15-E2S Accessories

If you’re pressed on time, here’s a quick list of the best accessories for bushmaster XM15-E2S:

  1. Vortex Spitfire 3X Prism Scope
  2. Ade Advanced Optics Ribbed Stealth Slip-on Rubber Combat Buttpad
  3. Bushnell Elite Tactical 6-24×50 Rifle Scope
  4. Streamlight TLR-1

1. Vortex Spitfire 3X Prism Scope

If you have astigmatism, it’s a good day to be an optics user.

The Vortex Spitfire is here and it’s providing a crisp and clean sight to use without any reticle bloom or “starbursting.”

Its 3x zoom, clear sight picture, and that Vortex logo promise to give you a quality optic with superb accuracy and confidence in shooting.

Here’s a look into the Vortex Spitfire 3X Prism Scope.


The Spitfire has a commendable construction; it looks sleeks, compact, and rugged.

The body is made up of aluminum, like almost every other optic on the market since that’s what’s going to help protect it from falls, bumps, and any other types of impacts.

The Spitfire is both water-proof and fog-proof. Thick o-ring seals make sure that water, weather submerged or in the rain, cannot seep into the internals of this optic.

The scope is also nitrogen-purged, ensuring that your optic won’t fog up in 10 below icescapes or hot desert treks.

This sight is constructed out of a single piece of metal; no seams to speak of. This tells me that the Spitfire was built with longevity and structural integrity in mind. Don’t go throwing this thing around, but you can expect it to take all the bumps and crashes with ease.

The finish is non-reflective black. Nothing is going to catch a glare coming off of this piece of equipment.

Let’s chat about the size.

You might be expecting something big and bulky, but no. The Spitfire X3 Prism Scope is compact, only a little larger than some red dots out there.

It has a length of only 5 and a half inches. I typically run a 1-6 LPVO, so this was such a nice change in my rifle’s profile. It’s small, unassuming, and powerful.

It’s not thick and bulky either, sitting up just a little over three inches.

Like I said, surprisingly compact for an optic with a 3x zoom.

The Spitfire also comes with three adjustment knobs, which is relatively standard.

The first is for reticle illumination, which admittedly is a little bit sparse on the adjustments. It’s still functional, I just wish there were a few more settings so I can fine-tune my optics for every situation, whether that’s home defense or hunting.

The other two dials are for adjustment, and there’s a plethora of increments you can use.

The MOA adjustment is changed by ½ with a single click on the dials, with over a hundred options. This gives you extremely precise adjustments.

If you’re worried about the weight, fear not! The Spitfire comes in at a slim 15 ounces.

Vortex Spitfire 3X Prism Scope weight

It’s heavier than your typical red dot, but the 3x and etched reticle makes it all worth it.


There’s also no specific mounting system to purchase since the optic comes with picatinny mounting out of the box.

Although keep in mind that having an absolute co-witness with your iron sights won’t be much of an option with this level of magnification.


The reticle is the biggest thing the Vortex Spitfire X3 Prism Scope has going for it in my opinion.

I have severe astigmatism making it nigh impossible to use red dots out past 50 yards, I looked around for a long time for something better but was relegated to short-range shooting and iron sights until I discovered etched reticles.

Vortex Spitfire 3X Prism Scope weight ocular

These reticles are, as the name implies, etched into the glass of the optic, meaning I didn’t have to suffer through reticle bloom anymore.

This is due to the fact that the dot is not a reflection of an led/light, but a physical shape you are looking through. In turn, there are sharp lines and extreme clarity when peering through one of these scopes.

Typically with magnified optics, you’ll suffer from something called parallax; the effect whereby the position or direction of an object appears to differ when viewed from different positions.

You’ll see this effect on long-range scopes, rangefinders, and binoculars, but the Spitfire doesn’t have this issue, even as a 3X optic.


Here’s the bread and butter of this product; its accuracy, and woo boy is it accurate.

I was hitting my shots with ease at 200 yards. The hits were all consistently about an inch and a half apart.

Vortex Spitfire 3X Prism Scope ocular

At about 300 yards I definitely had to have a little bit more patience, but I was still nailing shots without much of an issue.

Out past this distance, it becomes significantly more difficult to have good grouping. Between 400-500 yards I was able to ding targets, but not in a tight group.

It required a lot of steady breathing and patience with myself.

Frankly, if you’re using this optic as a duty optic or a hunting optic, I don’t reckon there’s a good reason to be attempting shots at 400-500 yards, but just know you’ll be able to tag ‘em.

At a lesser distance, it’s game over for those targets, if you’re a good shot that is.


Right now you can pick up the Vortex Spitfire X3 Prism Scope for $349.99.

This might seem rather daunting for those that are new to optics, but this is the price point where you start delving into quality attachments for your firearms.

Is the Vortex Spitfire X3 Prism Scope worth it?

Hands down, no debate, yes. Doubly so if you have astigmatism. This is a game-changer.

There are so many great things about this optic:

  • The etched reticle, this changes the game for enthusiasts with astigmatism.
  • The low profile, good magnification with a compact design
  • The accuracy, consistent and easy hit at the advertised ranges
  • A multitude of accuracy adjustments
  • The magnification, ideal for engaging close and distant targets

You’re doing yourself a disservice if you overlook the Vortex Spitfire 3X Prism Scope.

The price is absolutely worth it, and if you haven’t had an optic this high-quality, well it might just change the game for you.

2. Ade Advanced Optics Ribbed Stealth Slip-on Rubber Combat Buttpad

Sometimes the smallest details can make the biggest difference.

Whether it’s a new trigger, a different grain of bullet, or a hunting light for nighttime shooting, some items make you wonder how you ever did without.

Aftermarket gun accessories such as the Ade Advanced Optics Rubber Buttpad can make your rifle easier to hold, more comfortable to fire, and add recoil management to boot.

Best of all, it’ll cost you less than $20.

Read on to find out why you should own this slip-on combat buttpad for your rifle or shotgun.

What firearms will this buttpad fit?

The Ade Advanced Optics Ribbed Stealth Combat Buttpad will fit on any six-position stock for a rifle or shotgun.

In addition, the pad is easy to take on or off, as you simply slip it on the end of your stock and it stays put until you slip it off.

This means that you can easily use the same pad for multiple firearms if you desired.

However, this buttpad is so affordable that you could easily purchase multiple pads for all your different guns.

Why use a buttpad on a rifle stock?

While you might think of accessories such as the Ade Advanced Optics Combat Buttpad as an optional addition to your gun, it can be anything but.

The primary purpose of a buttpad is to help reduce recoil where your firearm meets your chest, which this pad achieves with a ribbed rubber surface.

But that’s not all it can do.

A well-designed pad also provides an additional cushion to save your skin from bruising or rashes if you aren’t wearing a thick outer layer when shooting.

However, one of the most important (though often overlooked) functions of a buttpad is to help you adjust your trigger pull.

The Ade Rubber Buttpad is about one inch thick, meaning it adds to your length of pull.

For taller shooters, this is more ergonomic and can even improve your shooting, and it’s cheaper and easier than getting a new stock.

That’s why buttpads can make such a big difference to shooters, regardless of whether you’re firing bullets, slugs, or hunting pellets.

Should I buy the Ade Advanced Optics Ribbed Stealth Rubber Combat Buttpad?

If you have a rifle or shotgun and want it to have:

  • Less recoil
  • More cushioning
  • A comfortable length of pull

From an accessory that costs under $20, you should definitely buy this pad.

Not only is it made for AR-15 style rifles – making it one of the best accessories for the Bushmaster XM15 E2S – but it also fits most rifle and shotgun stocks.

Plus, it’s affordable enough that you can buy one for each of your guns.

But even if you just get one, the simple slip-on design makes it easy to use the same pad for multiple firearms.

Lastly, this buttpad was designed to last, made from high-quality rubber. It even comes with a lifetime warranty, making this a fantastic purchase for any gun enthusiast.

If you’re still curious about this buttpad, I recommend getting one yourself and trying it out!

3. Bushnell Elite Tactical 6-24×50 Rifle Scope

The Bushnell Elite Tactical Rifle Scope is one of the best long-range hunting scopes on the market.

Whether you’re shooting small game from the bench or hunting big game while hiding in the woods, you won’t get this kind of long-range consistency from any other scope.

Bushnell Elite Tactical 6-24x50 Rifle Scope ocular

Bushnell set out to create the ultimate modern scope at a selling price of under $1,000.

Did they succeed?

Let’s find out!


The Elite Tactical 6-24x50mm Scope is argon-purged to prevent corrosion, and made with a one-micron solid-brass power cam and aluminum-titanium alloy springs, ensuring long term reliability. It comes in a non-glare, anodized blacked-out finish for optimum concealability, and is water, fog, and shock-proof.

Bushnell Elite Tactical 6-24x50 Rifle Scope

The 30mm main tube, objective and ocular bells, and saddle are all made from one piece of 6061 aluminum through a cold-molding process.

The RainGuard HD anti-fog technology keeps the lens clear, no matter the conditions, and the scope includes a 3” sunshade and a 4” eye relief. The adjustable parallax focus is mounted on the saddle.

Bushnell Elite Tactical 6-24x50 Rifle Scope turrets

The controls are easy to use with firm, tactile “clicks”. It features a rubber-cushioned, fast-focus eyepiece and rugged-looking dials and turrets.

Bushnell Elite Tactical 6-24x50 Rifle Scope dials

Bushnell crafts high-quality optics. This is a very durable scope that’s built to last.


This tactical target scope is fully adjustable and features a simple illuminated mil-dot reticle with a one-mil click value. It focuses on a single point, meaning the crosshairs will get bigger as you zoom in. Even fully zoomed, the mil-dots are perfectly clear.

The reticle is housed between two lenses for increased durability and marked with ten different illumination levels. This, along with the Ultra Wide Band Coating that provides 95% light transmission, makes it ideal for use in low-light situations.

Bushnell Elite Tactical 6-24x50 Rifle Scope lense

The target turrets are one of this scope’s best features. They feature 1/10-mil click adjustments, 5-mils per revolution, and are easy to move while wearing gloves. The markings are etched, rather than just painted, into the turrets, further attesting to the Bushnell’s quality.

These turrets promote increased accuracy and boost the stability of your shots, giving you precise positive target acquisition.

The only downside here is that the turrets’ adjustments don’t lock – making the scope vulnerable to accidental adjustments.

Bushnell Elite Tactical 6-24x50 Rifle Scope turrets

Overall, the Bushnell Elite Tactical Scope offers crisp, clear views and holds your zero perfectly. The fully multi-coated optics produce true HD clarity at long-range distances. From 200, 250, even 400 yards, the image is very sharp and target acquisition is a piece of cake.

Bushnell Elite Tactical 6-24x50 Rifle Scope

Even in low light conditions, the illumination works wonders. No matter how far from the target you get, the view is astounding.


The Bushnell Elite Tactical Scope is 13.5”, with a mounting length of 6”. The outside diameter of the objective bell is 2.3”, and the ocular bell’s outside diameter is 1.5”. It weighs 27 oz.

Bushnell Elite Tactical 6-24x50 Rifle Scope

It’s a big scope. A little heavier than most, but this doesn’t affect performance.

Since the objective bell is so large, make sure you use a high enough base. With low bases, you run the risk of the bell not clearing.


The scope kit (including the sunshade, lens cover, user manuals, hex wrench, and battery) MSRPs for $999. You can, however, find it at many online retailers for between $800 – $900. This price also includes a limited lifetime manufacturer’s warranty.

It’s a little pricey, but worth the investment. The durability and quality are on par with scopes twice the price, so it’s an excellent value for what you get.

Is the Bushnell Elite Tactical Rifle Scope Worth it?

The Bushnell Elite Tactical 6-24x50mm Rifle Scope is a high-quality long-range scope that’s capable of anything.

The consistent performance, modern features, and excellent sight picture make this scope worth every penny. It’s a very reliable piece of equipment that offers precise marksmanship.

I’d recommend this scope to any long-range shooter or big game hunter.

4. Streamlight TLR-1

The Streamlight TLR-1 is the industry standard for weapons lights.

In fact, it’s one of my favorite Bushmaster XM15-E2S accessories.

It boasts high light output and a relatively good price.

Is this just a middle of the pack light? Or does it shine from the crowd?

Let’s take a look.


The TLR-1 was built with the purpose of being an effective duty light meaning that durability is an important cornerstone of the light.

Streamlight TLR-1

Its frame is built with a machined aluminum sealed construction with an anodized finished. This frame makes it less likely to break when dropped.

Streamlight TLR-1 lens1 .

The lens is a high temperature, shock-mounted, and impact resistant Boro Float glass lens, although it’s worth mentioning that it’s fairly uncommon for you to drop your light lens straight down. You should mostly be concerned about the impact of dropping it on its side.

Streamlight TLR-1. lens

I dropped this light twice and besides a couple of superficial scratches, the light stayed fully functional and is still working now. This reaffirmed my confidence in the TLR-1’s ability to take a beating.

Like many lights in its category, it takes two 3 volt CR123 lithium batteries. These are cheap and plentiful enough so they’re easy to find. These will last you an hour and a half.

The size of this light is a little bit bigger than many compact pistol lights. If you want to keep your gun light flush with the end of the barrel, this is not the light for you. On my P-07 the TLR-1HL protrudes out about an inch.

Streamlight TLR-1. light

The overall length is 3.39 inches.

The weight is 4.32 ounces, which seems pretty light, but you can definitely feel the weight difference when you attach it to your weapon of choice, more so on pistols.

Streamlight TLR-1.

It features an ambidextrous switch that has an on/off as well as a hold for a momentary-on switch. I personally am a big fan of the switch.

I’m right-handed, so I use my dominant hand’s index finger to switch the light on. You can either depress the switch down on the right side or up on the left side to turn the light on.

The switch is responsive and tactile. The action is satisfying, clear, and also very, very visible.

Light Quality

If you’re switching from some cheaper or lower-end lights, you’ll be shocked at the difference.

The TLR’s light output is superb, I was easily able to see everything in detail at the far-end of my rather sizeable backyard, about 40 yards. In the woods or without a barrier to block the light, the throw went out to around 270 meters, pretty impressive.

The quality degrades a little bit at that distance, but the illumination is still visible.

The lumen output is 1000 lumens, which is a pretty large amount of light being thrown from this discreet device.

For those who are wondering (probably all of us), this light will not permanently blind you, but if you flash this in someone’s eyes it will force them to reflexively force them to look away. I tested this by flagging myself in a mirror and I was left seeing spots for a minute or two.

Don’t rely on it, but shining this light in someone or something’s eyes can deter, or at the very least, delay an attack.

The TLR-1 HL boasts a solid 20,000 candela, the beam is highly focused and won’t completely flood out. It’s an intense beam, just what you’re looking for in a gun light, whether it’s for a pistol, rifle, or shotgun.

Practical Application

There’s a range of ways you can use the Streamlight TLR-1 HL.

Streamlight TLR-1. rifle

You can use it on a rifle or a shotgun, but I’d recommend using it as a pistol light.

Streamlight TLR-1. with rifle

The design is definitely catering to use on a handgun and that is how I used mine. I keep my CZ P-07 locked and loaded in my nightstand, always within a foot of my person. The addition has made me feel more confident in sweeping and clearing my home, whether that’s for practice or if I hear a bump in the night.

The TLR-1 HL will illuminate an entire family/living room, allowing you to receive and assess information much more swiftly than just peering into a dark room. You can additionally point your light at the ceiling for umbrella lighting.

This technique breaks intense heat spots and disperses light across the ceiling and down the walls. In turn, you receive more even lighting in whatever room you’re standing in.

I also used this light to identify sounds in my yard. As previously mentioned, this light easily covers the entirety of my yard. I usually used it to look up in the trees to see what my dog was barking at. What I’m trying to say is that it’s effective for outdoor use and to positively identify subjects of interest (possums and raccoons).

Streamlight TLR-1.

This light is amazing for practical and everyday use.


The Streamlight TLR-1 HL is a cool $159.95 on Amazon right now. This might seem a little bit steep if you’re new to high-quality weapon lights, but this is a fair price for all the use and effectiveness you’ll be getting.

The Final Verdict

If you’re in the market for a new weapon light, go out and buy one right now!
