So our local range has USPSA and CQB matches once a month respectively. I've got an M&P15T with a foregrip, 2pt sling, and eotech 512. I'm using regular GI mags but I need some way to secure them. I was thinking about getting this And then use these Now this is just going to be fun for me and to better my rifle skills. Will this hold up and be ok you think? Are there any better mag pouches available reasonably priced? Any other tips are welcome too. Thanks.
