That is what I am thinking bought a new mag and a 3rd type of ammo, cleaned the gas tube out,even though not even 60 rounds now went through it. Needless to say it was clean. 2 times it actually loaded another round then went back to the normal crap. I contacted Adams Arms asking them to contact me. I took the BCG apart cleaned it, Needless to say again I didn't need to clean it. That cotter pin was fun to re insert lol. I have done everything. Looked to see if the BCG was hitting the walls(nothing) and the buffer tube looks new and functional as well. I have tried different grains expensive and cheap brands of ammo, Oiled it cleaned it, everything imaginable at this point. You I know guys could probably identify the problem in person, quickly. I am just not intelligent enough myself to detect the problem and find a solution. I tried to find a PDF owners manual to this firearm or a Youtube video of this model and break down. Can't find anything but a "one size fits all" pdf from the site, everything on the manual I know. Stumped. I really don't want to send it in and wait months on a return. They don't have a contact number so I can only email at this time. But I keep burning money here and I have done almost everything.
