The Brownells AR-15 magazine feed lip tool is engineered to precisely realign feed lips, ensuring they guide the cartridge body as intended. Using pliers to straighten the lips may result in rough, unsightly gouges or, more critically, irreparable cracks in the metal. The tool features a steel shank with a bevel cut and slot, enabling you to hook and support the lips while adjusting their contact angle on the cartridge case. This tool effectively refurbishes old magazines, eliminating the need for purchasing new ones.
