Bushmaster XM15-E2S ORC 5.56mm NATO Semi-Auto Carbine with UTG PRO Quad Rail, 16" Threaded Barrel
This Ilion-marked Bushmaster XM15-E2S Optics-Ready Carbine (ORC) is a factory AR-15 platform that leaves room for your choice of glass while adding a UTG PRO MTU001 quad-rail handguard for immediate accessory mounting. Built between 2011 and 2014, it features a 16" chrome-moly/vanadium barrel with a 1:9 twist, carbine-length gas system, and standard 1/2×28 threaded muzzle with an A2 flash hider. The forged 7075-T6 aluminum receivers, hard-coat anodized finish, and collapsible six-position stock keep the package lightweight and duty-ready.

The flat-top upper receiver runs a full-length 1913 rail, so optics or irons can mount anywhere you choose. A low-profile gas block replaces the traditional front sight base, giving you an uninterrupted sight line for modern optics setups.
The factory-installed UTG PRO quad rail is free-floating aluminum and made in the USA. It offers four continuous rails for lights, lasers, and grips without adding excessive weight.
Internally, the direct-impingement action follows mil-spec dimensions, ensuring compatibility with standard AR-15 parts and magazines. The chrome-moly/vanadium steel barrel balances accuracy with durability, while the 1:9 twist stabilizes common 55- to 69-grain 5.56 NATO loads.
The carbine-length gas system keeps recoil manageable, and the six-position collapsible stock lets shooters of different sizes find a comfortable length of pull. A2-pattern grip and sling loop round out the familiar controls.
