The Noveske Chainsaw 5.56 16in Complete Upper (Noveske part no. 03000523) is a turnkey upper receiver group built by Noveske Rifleworks around their signature Chainsaw forged upper. Noveske machines the upper from 7075-T6 aluminum with extended feed ramps and a Type III hardcoat anodized finish, then pairs it with a 16-inch, 416R stainless steel barrel cut with a 1:7 twist and chambered in 5.56mm. A black nitride, Noveske-marked forward assist and an ambidextrous Noveske Love Handle charging handle round out the controls, while a free-float M-LOK handguard uses Noveske’s anti-rotation interface to lock in place without shifting zero. The included bolt carrier group is phosphate coated, full-auto-compatible, and built with a chrome-lined carrier bore and key for reliable cycling run after run. Bolt this onto any compatible AR-15/M4 lower and you’ve essentially built a clone of the upper receiver group fielded by USASOC, ready for duty-grade reliability on a personal rifle.
