try a different bolt carrier.
That I should be able to try when my sisters AR (more like my backup...) gets here on Monday.
Sic semper tyrannis.
in that case you can pin on a new upper too.![]()
Strange. My frankenrifle consists of a PWA lower, LMT L7d1 upper, BCM bcg, and a G&R Tactical LPK. Put the LPK in myself and I have absolutely no magazine seating issues with USGI, or PMAG's loaded to thirty rounds on a closed bolt. The PMAG's will not drop free like the USGI's, but they will seat with a noticeable "click" with me using a firm one finger push.

I may have to give Noveske a call then, but I'll wait until I get to test some different combos once the other rifle gets here. Maybe its always been a problem and I just never noticed it. Interestingly though, I think its gotten worse. I fired 180 rounds today (always just slam it when actually shooting so I don't know how it felt then) but tonight it seems to have gotten worse. Initially I would insert the mag, it would stop, and then I could slam or I could just push harder to fully seat it. Now its much harder to push, so much so that I almost have to slam it in. Still no issues dropping free or feeding though. Its weird...
Sic semper tyrannis.
Let me get this straight, of all the magazines that you have inserted into your carbine, have any of them failed to seat and function as required? Pmags, USGI mags, empty, one round, 28 rounds, 30 rounds and everything in between, you've been been able to seat the mags, albeit with increased resistance, and still put rounds down range. No problems when you first got the rifle and now with PMags and USGI mags, it's getting worse? I don't know, maybe you can put a video on YouTube showing us this progressive failure of your Noveske. I'm sure Noveske would be most interested along with Magpul. You have a bunch of us wondering WTF.
As I'm understanding it, its functioning fine, just 'feels' harder. All mags take more effort to insert on a closed bolt when loaded.
amount of force needed:
open bolt = empty mag/closed bolt
2round closed bolt< fullmag/closed bolt.
It doesnt matter what mag you have. I have 3 usgi mags and had 3 pmags(gave some away - and yes small sample size, but still..._) all could be seated with 30 rounds. All took a little effort, but not much, to seat.
FWIW, I had mags fall when using the "slap" method, so I started pushing till I hear the *click* or push/pull method. I have not had a problem since. Its also quicker.
OP, look at things and isolate different part movement with your fingers (bolt catch, etc.) If there is no noticable problems, its probably fine. If you cannot physically seat the mag without an unreasonable amount of force, and using a veritable plethora of mags, my modest suggestion would be to send in the lower.
Edit - when you see the rounds not moving as stated in OP, its because the rounds hit the closed bolt, you need to overcome the spring force and slight friction so of course its gonna take more effort then an open bolt.
