Doublestar Corp Arp7 Pistol 5.56 7.5 30Rd

The Doublestar Corp ARP7 is a 5.56 NATO pistol built for shooters who want a compact, maneuverable platform without compromise. At 7.5 inches, the barrel strikes a balance between velocity and portability—ideal whether you're running a truck gun for overlanding, keeping a truck-bed defensive option, or setting up a nimble range rig. This semi-automatic direct-impingement pistol feeds from standard 30-round AR magazines and runs on a proven gas system, so feeding and function are never a question.

The ARP7's foundation is solid forged aluminum: a Type III hard-anodized 7075 aircraft-grade upper and lower receiver rated for duty. The upper is a flattop design with M4 feedramps, T-marks, a brass deflector, and ejection port door assembly—specs that matter when you're relying on the gun. A 4140 chrome-moly barrel with 1:9 right-hand twist delivers accuracy at 5.56 velocities, and a free-floating setup minimizes harmonics for consistent shot groups. The Big Timber muzzle brake keeps recoil manageable in a short-barreled package, making follow-up shots faster and more controlled.

Ergonomics and modularity are baked in. You get a billet Strongarm pistol brace for stability and support, a low-profile gas block that won't interfere with optics, and an Ergo grip for repeatable hand placement. The seven-inch Cloak MLOK handguard is where you customize: add a light, PEQ, or vertical grip to fit your mission. A billet Backbone charging handle rounds out the build—smooth operation you'll notice when you run the gun. Setup is straightforward: mount your favorite reflex or red-dot optic, load a mag, and you're ready to move and shoot.

This is a no-frills, well-engineered AR pistol for hunters, sport shooters, and owners who value reliability and practical ergonomics over flash.
