Best mags for an AR-10?

[nikonNUT]

So I have an MSR-10 and I am underwhelmed with the performance of the supplied MagPul Gen 3 mag. What is the best of the best? Too small of an investment not to have the best.

What is it that you dislike about the pmag?

Well, When trying to load a mag on the bench it just doesn't seem to lock home (it does snap into place) and the BCG slides over the round without picking it up. Maybe I just need push harder?

Are you loading the mag on an open, or a closed, bolt?

Open.

Just an AR-15... 30 round MagPuls. No issues...

Are you experiencing this issue with one or multiple magazines?

just the supplied 10 rounder. I'll take it apart and see what i can see. I really may be being to gentle with it.

I never could get my 10 rounders to work 100%. I always had good luck with the 20 and 25rd ones though.

The 10 rounder was a bit balky going back together and the spring was sticky. I'll clean it up and see if it behaves better. Thank you for the insights!

Gave the mag a good scrubbing with PGA and it seems to be acting better! I'll test it next weekend!

I always run the pmags without issue. Tried an off brand one time and went right back to Magpul.

Push it in until you think it is seated then pull on it to make sure it is.

In my LMT MWS I've had an issue with pushing the mag too far up into the magwell and getting the first round hung up when charging it. So now I am less forceful and push in and pull it down to make sure it is properly seated and locked.
