A new model from Bushmaster, this XM15 E2S M4 Type Post-Ban Carbine features a lightweight 14.5" Barrel machined in the distinctive M4 profile with a permanently attached Mini Y Comp muzzle brake. This configuration yields a total barrel length of 16" to comply with Post-Ban regulations. A BATF approved fixed tele-style buttstock is added to complete the military look of this new carbine. 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. The tele-stock style buttstock is pinned and fixed in an “open” position and has been BATF approved for use on Post-Ban manufactured carbines. 

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. The M4-16 Carbine is shipped in a lockable, hard plastic case - complete with 10 round magazine, carrying sling, and Operator's Safety and Instruction Manual.
