So why get accessories for your Bushmaster XM15-E2S? Well, the XM15-E2S is a premium quality AR-15 style rifle available at a reasonable price point. This rare combination of quality and affordability have caused it to be an extremely popular rifle.

However, it is rare that an out of the box rifle has everything the end user might desire, and that set us on the quest to find the right XM15-E2S accessories. Because this is a rifle that is a cut above your average AR, so are the accessories we looked at. From high end optics to superior sling systems, we’ve got you covered.

Below are our recommendations for the 4 best Bushmaster XM15-E2S accessories on the market:

XM15-E2S Accessory 1: Bushnell Elite Tactical Scope

There are many different XM15-E2S configurations, including match target models. Such precision rifles demand a precision scope, and the Bushnell Tactical Elite is one such optic. Built with 6-24 magnification for close or long range shots, a huge, light gathering 50mm objective lens, illuminated reticle, and of course water, fog and shock proof construction (see full specs), this scope really does live up to the “Elite” name.

Of course the quality construction doesn’t stop there. This first focal plane scope also has unique multicoated optics that offer a crystal clear sight picture even in bad weather, side focus parallax adjustment, and so much more. While not cheap, the unbeatable combination of a first focal plane scope, that is also highly suitable for use on a match grade AR-15 target or sniper rifle, really brought it all together as an ideal optics choice.

XM15-E2S Accessory 2: Streamlight TLR-1 Rifle Kit

Another XM15-E2S variant is a traditional 16” carbine with an adjustable stock. Such handy carbines are often used for patrol rifles, ranch guns, and for home defense. In any of those uses, you’ll find great value in having a high quality weapons light installed.

The famous Streamlight TLR-1 is perfect for that role, and is easily one of the best Bushmaster XM15-E2S accessories for the money. This powerful 800 lumen weapons light (see full specs) readily mounts to any standard Picatinny rail, and features a programmable strobe mode, and a remote activation switch. This advanced shockproof light has a 50,000 hour bulb, and can run for almost two hours on a pair of fresh CR123A batteries. If you need a light for your favorite carbine, this is it!

XM15-E2S Accessory 3: Otis Modern Rifle Cleaning Kit

Presumably you are shooting your XM15-E2S enough to actually have to clean it from time to time, which means you need a decent sort of cleaning kit. The Otis modern rifle cleaning kit is a handy, pocket-sized kit that has everything you need to clean your rifle. The multi-piece poly coated cleaning rod is made of flexible steel cable and will not scratch or damage your barrel, while the complete assortment of bore and chamber brushes ensures a quality deep clean.

As an added bonus, there is a special carbon scraping tool, and a complete array of fine tools for even the deepest cleaning of any part of an AR style firearm. I’m hard pressed to think of any reason not to get one of these cleaning kits for your XM15-E2S, or any other modern sporting rifle for that matter.

XM15-E2S Accessory 4: Rubber Extended Buttpad

“But my XM15-E2S doesn’t have any recoil,” you say, while wondering why on earth you’d need a buttpad for a .223 rifle. The simple answer has nothing to do with the negligible recoil, and everything to do with length of pull. Taller than average people often benefit from the extra length a quality buttpad can provide, and if you are wearing body armor, heavy clothing or tactical gear, even a fully extended stock may not give you a comfortable length of pull.

This simple, slip-on rubber buttpad adds over half an inch of additional length of pull, which improves ergonomics, and can make shooting in thick clothing or gear far more comfortable, while improving your shooting. Hey, considering its price, why not grab one for each of your AR style rifles?

Choosing the Best Bushmaster XM15-E2S Accessories

There is literally an XM15-E2S for nearly any situation. Ranging from tactical carbines to precision match target rifles, choosing the best accessory is as dependent on the gun you own, as your own individual needs. Some of Bushmaster’s fines XM15-E2Ses are heavy-barrel target rifles, and those all but require a high end scope to go with them. And if you don’t like the Bushnell Elite, we have reviewed a great many suitable scopes elsewhere on this site (see them here).

By and large, though, the bread and butter of the AR-15 world is some sort of 16” carbine with an adjustable stock, and the XM15-E2S is no exception. This handy carbine begs for accessories like a quality tactical light, or even a simple rubber buttpad, or perhaps even a high quality red dot sight (Eotech or Aimpoint).

You will find these are premium grade carbines; therefore, the best Bushmaster XM15-E2S accessories must also be premium quality accessories. After all, there is a reason so many have chosen them as patrol and personal defense carbines. Where your life or that of another person’s is on the line, do you really want some cheap plinker grade accessory?

It is a truism that you get what you pay for, and you’ve already paid for one of the best production AR-15’s on the market. All that remains is to take that next step forward and carefully complete your purchase with the optics or other accessories that you need. The XM15-E2S will serve you faithfully for years to come, isn’t it worth the trouble to get the best upgrades for it too? Good luck!
