i recently bought the metal 5/30rd metal mag from HI Caliber. i took out the boxmag and re-attached the trigger mechanism. now i try to insert the mag and it wont go in right. however if i try to just put it in without locking in the front part (that looks like an it) it fits well. however it i try to lock that in first and then push the other side of the mad in it doesn go in well and if it does it get stuck with the mag release clamp. what should i do??? also can i leave the mag stuck in there and just use stripper clips to load???
thank you
