Overview
The NLX450 Bushmaster Complete Upper converts an AR-15 lower to .450 Bushmaster for straight-wall deer and hog seasons. Next Level Armament builds it on its forged NLX556 upper, whose ports it opens for big-bore cases, with a Tromix 16-inch carbine gas barrel in a 1:24 twist. The bolt carrier is Next Level's DLC NLX556 carrier running a Tromix .450 Bushmaster bolt.
It also includes the NLX556 ambidextrous charging handle, an NLA billet low-profile gas block, a 13-inch NLA M-LOK handguard, Next Level's NLX-11 brake in the standard 11/16x24 thread, and an extra power buffer spring to manage the heavier cartridge. Use .450 Bushmaster magazines in the lower.
