Machined from a billet monolithic aluminum upper receiver and forearm housing, this complete upper drops onto any mil-spec AR-15 lower using standard takedown and pivot pins - no permanent modifications required. It replaces the conventional AR direct-impingement gas system entirely with a patented long-stroke piston and dual reciprocating operating rods (U.S. Patent No. 9,032,860 B2), eliminating the need for a buffer tube or buffer spring from the lower receiver. The 16\" QPQ nitride-finished barrel is chambered in 5.56 NATO\/.223 Remington with a 1:8 twist rate and ships fitted with a Faxon MuzzLok Ported Brake on 1\/2x28 threads. The upper and lower handguard plate are finished in a warm, medium-gray Tungsten Cerakote - an industry-leading ceramic coating offering superior corrosion, chemical, and abrasion resistance - available exclusively through Sports South authorized dealers for a limited production run.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePatented Long-Stroke Piston System:\u003c\/strong\u003e Dual reciprocating operating rods run alongside the barrel inside the monolithic upper, keeping gas out of the action for a cleaner, more reliable cycle - especially suppressed or in adverse conditions (U.S. Patent No. 9,032,860 B2).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo Buffer Tube Required:\u003c\/strong\u003e The self-contained recoil system lives entirely within the upper receiver, freeing the lower for folding stocks, side-folders, or PDW braces.
