20 round Pmag issues?

[99HMC4]

Okay, Ive come to the point that Ive used my few 20 round Pmags enough to think I might have an issue with them. I have feeding issues with my SCAR and my Novekse lower/BCM upper rifles. My AR wont load a first round 50% of the time with the 20 rounders and wont lock back about 50% of the time with them. And i had my first ever failure to feed in my SCAR the other night with a 20 rounder (had to use my charging handle as a forward assist). This ONLY happens when I use 20 round Pmags in bothe guns, never had an issue with the 30 rounders. Any ideas?

I have the exact problem with my ARs and the 20 rounder. I only have one and I save it for the bench now. This has happened with a full mag and has also happened with three rounds loaded. I thought it was just my 20 round p-mag, but apparently not.

No, Im pretty sure its the mags. Both of my 20s do it in two different rifles. I never have issue unless I use thes mags. It sucks to cause I keep the smaller 20 round mag in my SBR for home defence but after all the issues Im having, I dont trust the 20s at all....

FWIW, I have had the same problems with 20 round Pmags. Bought a couple of new ones, but have not had a chance to try them yet.

Well magpul? Any ideas?

I've two Noveske's that have had several 20's and a few 30's fail to lock back after the last shot. Happened enough that I don't use P-Mags. I use USGI mags only. I've read a couple of places about Noveske/P-Mag issues on locking back.

I've tried at least 35 new and used USGI mags and not a single failure. I bought a couple NHMTG 20's this past weekend to try out.

This is the reason you should test every mag in every gun before you depend on it.

I know this dooms me to a life lacking tacticoolness but ...oh well.

I love magpul but I dont trust the 20s anymore. They are plinker only parts now. Gonna get some good metal 20s now for home use.....

I have 4 of the 20's and they all work fine for me. 2 FDE, 1 Dark Olive, 1 Black. Never had a problem with them.

Disclaimer* - they run with safe queen upper because they work better from a bipod. They haven't been through a carbine class or anything like that.

This is interesting because my lower is a Noveske. Maybe we're on to something now. Would be nice if Noveske would check into this for us and perhaps provide an aftermarket solution?

The only failures I've had on any of my ARs are with PMag 20's. Only with certain ammo (Tula/Wolf) and always on the 2nd to last round failing to feed, I'd say 9/10 times. The 30s feed that ammo fine, and the 20s feed other ammo fine. It's strange...
