Details

The Aegis 18-inch Carbine-Gas .350 Legend AR-15 Full Build Kit from Davidson Defense is engineered for performance and customization. This kit delivers an 18-inch HBAR barrel made from 4150 CrMoV steel, featuring a 1:16 twist rate for stability with .350 Legend ammunition. The carbine-length gas system utilizes a micro low-profile gas block for reliable operation, while the 15-inch freefloat M-Lok handguard provides versatile mounting options for accessories.

Constructed from durable 7075 T6 aluminum, the upper receiver is anodized for added protection, and the kit includes an AR-15 M4 charging handle. The complete bolt carrier group, crafted from premium alloy steels, ensures robust functionality. Additionally, the KAK Industry Plan B A7 flash hider—with its 5/8×24 thread pitch—reduces muzzle rise. The adjustable Gauntlet Arms carbine stock, combined with a heavy-duty buffer tube, offers comfort and adaptability for diverse shooting scenarios. This build kit equips gunsmiths with everything needed to assemble a reliable .350 Legend AR-15 rifle.
