Bushmaster XM-15 QRC Complete 5.56 16" 1:8 Nitride Lightweight Barrel AR-15 Upper Receiver 00-40003-BLK
This Bushmaster XM-15 QRC upper will attach to virtually any standard AR-15 lower receiver. Comes complete with salt bath nitride M16-style bolt and carrier group, charging handle, forward assist and ejection port cover. With a 1 in 8" twist, the 16" chrome lined lightweight "pencil" barrel provides outstanding accuracy in a very lightweight build overall. Pre-ban style upper includes a bayonet lug and flash hider.
NOTE: These are some of the last of this once great AR-15 manufacturer's uppers left available on the market today. Unlike most heavier railed builds & uppers, this one is a classic 2-piece heat shielded handguard carbine upper with what is rare for today, a lightweight pencil barrel for a truly minimalist build. Throw on your favorite red dot or low powered AR optic & this will be a carbine you'll carry all day.
