XM15 E2S M4 Type Carbine features a lightweight 14.5"" Barrel machined in the distinctive M4 profile with a permanently attached IZZY muzzle brake. This configuration yields a total barrel length of 16". A 6 position tele buttstock is added to complete the package. The 14.5"" barrel is chrome lined in both bore and chamber for maximum longevity and ease of maintenance. The barrel's button rifling, in a 1 x 9"" right hand twist, will stabilize a wide range of currently available ammunition with bullet weights up to 69 grains.
The M16A2 dual aperture, rear sight system offers both windage and elevation adjustments - elevation is calibrated from 300 to 800 meters. The two different apertures give either a short range, quick target acquisition sight picture or a smaller peep aperture for long distance accuracy.
As with all other Bushmasters, the forged 7075T6 aircraft quality aluminum receivers are finished in a non-reflective mil. spec. hard anodize for durability, and include all M16A2 design improvements such as cartridge case deflector, last round bolt hold-open and raised ridges for magazine release button protection. A mil. spec. manganese phosphate coating insures complete protection against corrosion or rust on barrel and other exposed steel parts.
