 Complete, ready-to-install, semi-auto receivers let you change your AR-15 from a sporter to a match rifle or long-range varminter in just minutes—or add to a lower receiver to complete a parts gun. All barrels have six-groove, 1-9" right-hand twist rifling and M4-type feed ramp. Pre-ban style standard (Std) barrels are chambered for 5.56mm NATO, with A2 flash suppressor, military-style polymer handguard, and A2 front sight housing that includes bayonet lug and riveted sling loop. AP4 adds to Std configuration the cutout for M204 grenade launcher mount to replicate the contours of the USGI M4 carbine barrel. Bull barrels are stainless steel, post-ban style, and chambered for .223 Remington, with low-profile Picatinny gas block, aluminum free-float handguard, and non-threaded muzzle with target crown. Most models available with standard manganese-phosphate Parkerized bolt or Chrome-plated bolt for additional lubricity and wear resistance. Oracle – 16” lightweight upper, chrome-moly barrel, railed gas block and A3 upper. TPR features a stainless steel 20" HBAR 416 stainless steel barrel with a 1-9 twist.  Includes a M111 modular handguard. TAC2 features a 16" 4140 1-9 lightweight barrel with a rifel length gas system. Includes front sight and M111  modular handguard.
