The Luth-Ar Rifle Kit Bull 20 W/ Fixed Stock from Luth-Ar delivers a complete AR build solution centered on a 20 fluted bull barrel upper with a 15 keymod palm handguard, paired with your choice of either an MBA-1 Fixed Rifle Buttstock assembly or MBA-3 Adjustable Carbine Buttstock Assembly, and a fully assembled Lower Parts Kit to help you craft a ready-to-fire platform around a Mil-Spec stripped lower. This turnkey kit includes an assembled 20 bull barrel upper featuring the HG-V-15K vented palm handguard, the BL-B18FT 20 Bull Barrel Fluted with a threaded 1/2 x 28, the FTT-EA1 A3 upper receiver assembled, the BC-A-223 bolt carrier, the BL-04 rifle length gas tube, the GB-LP936 gas block, and the BL-06-A2 flash hider, all engineered for .223 Rem with a 1-9 RH twist, six lands and grooves, and M4 feed ramps.

Note that the kit does not include the lower receiver, which must be supplied separately, and a Mil-Spec stripped lower is recommended. This package is ideal for shooters seeking a high-quality, ready-to-assemble AR platform capable of precision shooting, competition readiness, and dependable field use.
