The machining tolerances on this, and every product/service from PMM honestly, are just phenomenal. There is no play whatsoever and it mounts rock solid. I couldn’t be happier with my b.c.d. and it blows all other similar products away. The details are well thought out, such as the lightening cuts in the bar so you don’t have to remove the b.c.d. to install/remove the hammer pin. The shape is perfect as it doesn’t hinder the ability to operate the ambi mag release either. Overall, if you’re contemplating picking one of these up, just do yourself a favor, stop reading reviews, and get it. You will not be disappointed. PMM really is in a league of its own.

Did exactly what I needed with the bolt. Not in the way at all. Made very well. Ione of the Most important upgrades tot he mcx if you actually run you gun. Failures are bound to happen. This cuts the steps in half to clear jams!
Great work guys and will be buying more stuff from you as you keep leading the development side

Exactly what I was looking for. On my AR’s I either have an ambi lower or a Magpul BAD lever. I found this product while looking at a different PMM item and ordered it. The install was easy and I love it.

Very high end and sturdy. Doesn’t wobble and a perfect fit for the MCX Virtus. A no-brainer upgrade.
