Barrel and Gas System

It runs a carbine-length gas system through a stainless steel gas tube, and it's built with a fixed M4-style front sight base that includes a front sling attachment point. The muzzle carries an A2 Birdcage flash hider.

Upper Receiver and Handguard

The upper receiver is a 6061 billet, slick-side unit with a fixed A1 carry handle, machined from 6061 aluminum and finished in black anodizing, and it includes a 6-piece A1 rear sight combo along with the ejection port door, rod, and spring. This upper is in a slick-side configuration, meaning the forward assist is not included. It's paired with a carbine-length drop-in M-LOK handguard finished in Flat Dark Earth.
