looking for short mag to attach the tapp airsoft adapter to? I have 3 mags for sale. 1 missing feed lip. $20 2 has everything you need for the tapp adapter. $25 each (can remove the base since you don't need it). located in the houston area so local meet up is preferred, of you buy only 1 and need shipping it will be shipped without tracking, but if you want tracking just pay the difference. If all 3 are purchased then I'll ship for free with tracking.
