The Shark Coast Tactical P-51 Mustang is a 5.56 NATO AR pistol with a 10.5-inch black nitride threaded barrel and an SB Tactical SBA3 brace (Shark Coast part no. SCC07442P51-P). It uses an aluminum receiver with a Picatinny rail, an M-LOK handguard for lights and accessories, and a Magpul MOE grip. The 30-round capacity and short barrel make it a compact platform for range use and home defense. The brace gives the pistol a way to be shouldered against the forearm for stability without a stock. It is a good base for anyone building a short, maneuverable 5.56 pistol.
