This item is trash by FAB defense magazine coupler, Verified Owner, October 7, 2025
I bought it because the description said it fits 556 AR mags,,, but to my surprise, the screw isn’t long enough to screw it back together once you put the mags in… why does the description say it will fit but it doesn’t?????

Locks in tight with ultimags. Solid lock up. Takes a sec to figure it out if you're not paying attention. And it's adjustable.
