Easy-To-Swap, Complete, Fully Assembled Top Ends; Carry Handle & Flattop Models; Lots Of Options
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. 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.
