The plastic seems thin but it has been taking the punishment with repeated drops from ejecting mags. You have to get it pretty tight to prevent the mags from slipping when hitting the ground especially with rounds left in the mags. This does not fit MSAR latest generation of mags. I shoot 3 gun matches periodically.
Pros: Low cost, easy set up
Cons: There were no included recomendations on propper placement
