Instruction Manual

Pg. 3
• This Operating Manual covers all Bushmaster XM15 E2S and Carbon 15 models chambered for
5.56mm NATO/.223 Remington ammunition. They are lightweight, gas operated, air-cooled,
magazine-fed rifles, carbines or pistols that are Semi-Automatic in operating mode (i.e., a single
round will fire each time the trigger is pulled). Note: For Law Enforcement and Military markets,
Bushmaster makes similar models in either Full-Automatic (continuous fire as long as the trigger
is pulled) or Three Round Burst (a group of 3 shots will fire as long as the trigger is pulled)
configurations. Sales of these models require special permits and are regulated by ATF.
• On all models, the Upper and Lower Receivers are easily opened for cleaning and inspection.
XM15 Models have forged aluminum Upper and Lower Receivers. Carbon 15 Models have
Receivers that are injection molded from Carbon 15 Composite.
• Most Bushmaster models feature fully adjustable rear sights / elevation adjustable front sights.
• Barrels on XM15 and Carbon 15 Models are either chrome lined Chrome Moly Vanadium Steel or
416 Stainless Steel. They are usually button rifled 1 turn in 9” with a right hand twist - 6 lands and
grooves. The Bolt Group locks into the Barrel Extension with 7 locking lugs.
• All models can be configured with either 6 position Telescoping Buttstocks or solid A2 “Trapdoor”
Buttstocks. Forends are of removable split design and are vented to allow heat dissipation. All
models feature vertical pistol grips and detachable magazines. Magazine capacity is 30 rounds
standard (depending on State Regulations), but all AR-15/M-16 Type magazines of capacities
from 5 to 40 rounds will fit the Bushmaster and function in it.
