A fine item , To be sure !
Perfect upgrade!!! Who doesn't love slick operation, negligible clean up after shooting all day and minimsl if any lube needed. Drop in rewards for avid shooters!!!! Happy camper!!!
Used SAA bcg's many times. Work as advertised. Last time I ordered two, only received one. SAA was on it right away, immediately sent me a tracking number for my other BCG. They are a top notch outfit. A+
Fast delivery, good price, high quality, fit like a glove and works perfectly in my AR.
High quality part. Finish is smooth and functions flawlessly in my 300BLK 7.5" upper. Will definitely buy more from surplus ammo! A++
