I have both, 5 and 10 round pmags. Run them in a Bighorn TL2
Using them right now for a 6br and haven't had a single nose dive.
Only problem I've had was the bolt would hit the front of the mag.
Just had to lightly sand the top down a little, till the bolt would
pass over the top and pickup a round. Had to do this with both
5 and 10. Don't know if this is a TL2 problem only, maybe the mag seats
too deeply, and others don't?
Not a big problem to fix once. They run fine now. All I use.
Half of the price of metal.
Never had a problem with 6.5 or 6 creed, after I fixed the problem.
