Here is my little franken gun. I'm waiting for my stamp back ono d an SBR, was going to have .22 and 9mm uppers, decided to dedicate the pistol lower for the .22 since it doesn't need the buffer tube.
If you want the spikes pistol buffer plug, order it from Brownells when you need to order other parts, Spikes rapes you for 10+ on the shipping of a 20 dollar part.
