Used once so far with no issues with a DPMS AR15 carbine. Max ammo is 14, but that's not a big deal.

If you are in a state that has a magazine round limit as NJ, this is a great choice. The clip that holds the two together is nice and easy to pull a part. When using the two together, the mags are not in the way and the weight being off center is not an issue. I would recommend this product to anyone in the situation where mag round limit are enforced.
