APF ELITE LTR 22ARC 16" Proof Lightweight MLOK Tactical Rifle

The APF ELITE LTR 22ARC 16" Proof lightweight MLOK tactical rifle is built for shooters who want a purpose-built, modern platform without excess weight. Alex Pro Firearms engineered this rifle around the 22 Arcane cartridge—a flat-shooting, low-recoil intermediate round that's become a favorite for precision work and field shooting where ammunition efficiency matters. The 16-inch Proof Research carbon fiber barrel keeps the gun handy without sacrificing velocity or accuracy, while the lightweight construction means you'll actually want to carry it all day.

From the rail to the trigger, every component here serves a function. The 15-inch MLOK handguard gives you plenty of real estate for mounting optics, lights, and other gear without the bloat of a longer chassis. Proof's Elite Series muzzle brake manages recoil and flash, the Superlative Arms adjustable gas block lets you dial in reliability with your chosen ammo, and the DLC-coated lightweight bolt carrier group reduces moving mass—meaning faster target reacquisition and less fatigue on longer range sessions. The Timney Impact trigger breaks at 3–4 pounds with a clean, predictable single-stage feel that rewards good shooting fundamentals.

The Mission First Battlelink Minimalist stock and Magpul K2 grip keep controls intuitive and ergonomic. An ambi safety selector means southpaws and ambidextrous shooters won't fumble in the moment. This is a rifle that works whether you're zeroing at the bench, running drills at a tactical course, or hunting varmints where every round counts.
