Uses standard bcg, great choice for 9mm - Maxim Defense Industries CQB Stock Gen 6 for AR-15

I’ve used these throughout the years on everything from 9mm to 22lr in the AR platform. Unlike some other pdw stocks, you can run a normal BCG, which is great if you need a pdw stock for direct blowback 9mm, you won’t have to remove the weight in the rear of your 9mm bolt.
