Davidson Defense Aegis Lightweight 16-inch Carbine-Gas 1:8 5.56 NATO AR-15 Freefloat M-Lok Handguard Rifle Upper Build Kit

Aegis Lightweight 16-Inch Carbine-Gas 1:8 5.56 NATO AR-15 Free-Float M-LOK Handguard Rifle Upper Build Kit

The Aegis Lightweight Upper Build Kit is built around a 16-inch 5.56 NATO barrel machined from 416R stainless steel in an M4 profile, with a carbine-length gas system and a polished stainless finish. It is paired with a black free-float M-LOK handguard machined from 6061-T6 aluminum and a 7075-T6 aluminum upper receiver. The polished stainless barrel gives the build a bright, corrosion-resistant look that stands apart from the usual black-finished barrel, and the 1:8 twist suits a wide range of bullet weights in 5.56 NATO. BCG and charging handle are not included.

Barrel and Gas System

The 16-inch barrel is machined from 416R stainless steel in an M4 profile and finished in polished stainless, a bright, corrosion-resistant surface. Its 1:8 twist rate is suited to a wide range of bullet weights in 5.56 NATO. The barrel is set up for a carbine-length gas system with a .750-inch gas block size, and 1/2x28 muzzle threads carry the included TPI GI birdcage flash hider.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished in anodizing, giving it a hard, wear-resistant surface that holds up to regular handling. It is paired with a black free-float M-LOK handguard machined from 6061-T6 aluminum. As a free-float design, it leaves the barrel free of handguard contact, and the M-LOK slots give the builder room to mount lights, grips, handstops, and other accessories wherever the setup calls for them.

Compatibility

This kit is built for AR-15 lower receivers chambered in 5.56 NATO. Handguard length, gas block and gas tube details, feed ramp style, and ejection port door and forward assist configuration were not supplied with this listing and should be confirmed before purchase. Because the BCG and charging handle are not included, they must be sourced separately to complete the upper.
