A1 ARMORY ALWAYS HAS EXACTLY WHAT I NEED!
I only needed a roll pin, but the price on their AR-15 bolt catch plunger and roll pin spring kit, was so good I ordered 3 kits just in case. Everything fits perfectly, and A1 Armory - unlike many parts and accessories houses - DOES NOT bend their customer over on shipping costs. If I need it, and A1 has it, I'm buying it from them! A1 is fair in all areas of their business, from ads to shipping costs, and their shipping is quick also. Join me as a loyal A1 Armory customer, and no longer wonder about "Did I get a good deal?"
