So after reading a number of the posts on here I want to thank everyone for giving a heads up to the potential issues with this rifle. Because I was warned I took the rifle apart and checked all of the connections. Handguard screws were very loose and the gas block was tightened down but no thread locker was used. I didn't move anything just removed one gas block screw added blue thread locker and reinserted, tightened by hand. Then the other. Same with all of the handguard screws. I then took everything apart and cleaned it up really well. The packing oil was pretty thick and out of the box I could barely pull back the charging handle. After a good cleaning and lubrication, it loosened up a lot.
I took it to the range and I had 5 types of ammo to test it with. First was the Norinco surplus steel case, and it wouldn't even feed, jammed up the mechanism and was a pain to clear. After that we decided to not do that again. Lol. So we switched to all brass case ammo. We had Federal 308 150 & 180, Remington 308 180gr. All were lead tipped hunting bullets. We also had the Hirtenberger surplus 762x51. We used magpul Pmag gen 3 and all of the brass fired 100%, no failures to feed or eject, bolt hold open worked on every mag. We fired off between 80-100 rounds with not a single hiccup in operation.
My guess is that in the rush to get these out the door, we were all screaming at Arms East because we wanted them so bad, that some final assembly details and QC was overlooked. I don't know if it is standard practice for Stag to add a drop of thread locker at assembly stage? If not it might be useful to give them some feedback.
As far as cleaning a gun before first use, we all know we should probably do it. I have been guilty of not following that good advice and shot a number of guns "right out of the box" and had varying results. This gun is not alone in having to check a few things, but with the shipping oil, they really need it. The difference in cycling the action from out of the box to after a proper cleaning was like from, I can barely cycle this I am going to have to buy a new extended charging handle this is so stiff, to a smooth tight mechanism that functions well.
Yes it would have been nice if Stag had delivered and functioned tested each one, but that would have been a further delay. I am just glad to have one that we can shoot for now anyways.
Thanks to Arms East for bringing these great NR rifles.
PS There is no such thing as an assault rifle. Assault is what one person does to another regardless of what tool they choose to assault them with. Put the blame where it belongs on the person not the object.
