Works perfectly just as designed for my MCX and it’s a quality product. I had not previously noticed the other review but pleasantly found out for myself that this product also works great for the Sig M400. I had found it difficult to find definitive information on a BCD that would work. I’ll be ordering a second one as well as other quality PMM products.

I cheaper out and bought the other style without the lever, (still worked great) but the lever really is a game changer to not have to give up your support hand any longer than necessary. 100% top quality machine work and finish!

One of those rare products that actually performs better than advertised and costs have of what it’s worth. This device makes magazine swaps and shooting in general a much more enjoyable experience. It’s like a cheat code for shooters.
