Just got an ae mark iii from my friend, but he already put about 3000 rounds through the barrell. I have read some reviews about markiii, some of them said that 3000 rounds just fine(some of them says the tube life could take 10000 rounds
). However, still looking to buy an extra tube. I have watched an video said that ae tube was different than other ai series, the aw barrell is all the way threaded, for ae, the recoil lug covered area has no thread. So, is it ok to but an aw or ai series barrel?? Thanks all gunners, your answer will help me a lot
