I just used 2 PRI mags today for the first time. I wasnt impressed with them at all. They did perform and function perfectly but I did not try to load either one to the max. Compared to other AR556 brands like Lancer you can tell they are lacking in quality. Even my M1A magazines feel like they are better quality.
Someone needs to step up and start making something high quality for 6.8s like LAncer
