From what I've gleaned off the thread on Enos, most guys are opening up the loading port and throwing a mag extension and they seem to work good. Some guys are saying they have polished the mag tube so the recoil spring operates with less friction, allowing them to run lighter loads. I've also read (and in my experience so far) that the lifter is good to go out of the box, with no modification required.
I know that Jesse Tischauser runs an M3000 with minimal mods.
Jesse T doesnt need any mods, he is the mods, lol
kidding aside, I did some math on the MOA M3000 base on their website, with all the mods and upgrades ,importation fee ,shipping plus dollar conversion, your seeing abou $1200.00 min. I might be wrong, MOA seems doesnt have the enthusiasm in answering my inquiries, I emailed them my intentions and plans even the mods that I want, its been 5 days and havnt heard from them again. Maybe will just get an 1301 here loca
