·Having some problems with my new upper and I'm in need of some advice. I am in the process of assembling a new 16" carbine. So far I've only purchased the upper (a Stag 3H with a low-profile gas block). So today I was able to put several mags of Wolf through the upper using a RRA lower half with an Ace A2 length skeleton stock. Not too sure what the buffer weight is, but the RRA lower half is from a factory midlength. Well.....I had several problems with shortstroking and failure to lock back on last round. I will try to use some quality ammo later in the week (it was freezing cold today), but for now I'm wondering what's going wrong. Is the A2 length stock causing the problems.....Wolf ammo maybe???? The carbine length gas system is brand new for me, so any input would be greatly appreciated. Oh, as far as mags are concerned...I was using 3 different USGI mags (two 20 round and one 30). It didn't short stoke every time (had several 5-10 round strings with no issues)...but it was frequent enough to be a problem. What do ya think? Many thanks.
