i have one that i put on my remmy, i ended up taking it back off. after about a year, it started poping open, and dumping all of the ammo on the ground when ever it felt like it. i tried to fix it, with no luck. a pain in the keester at the range, a real problem out in the woods! i suppose if you wanted to glue it closed, and use it like a blind magazine. but i just do not like that kind of stuff.
