Hello all. New to the site. I Have a NEW SU16A that I bought, I know its a cheap rifle and what its purpose is so I dont want the "its a P.O.S. shouda bought a mini 14 deal". I bought it because it is very compact and light to have around when im on trips. The issue I have and have not found online is will only fire with the kel-tec mags it came with the two 10 rds in the stock. I bought some 30rd Pmags and went to the range and loading the first round it takes the bullet and slams it in between the ramp and stock and actually flattened the tip of the round. my friend that was with me had me try three different mags he had, one of them steel. Still no luck. put the Kel-tecs in....no problem. Thinking of taking the dremel to smooth out the feeding ramp/stock. Any one had this problem?
