Teal Blue Bravo’s PDQ Ambi Bolt Release on CMMG Guard

I’ve been using the PDQ for a few years now on 556/300BLK builds with no issues after profiling the side so that it isn’t fighting the dust cover as much.

On the 9mm Guard, the receiver is more narrow so you don’t need to modify the ‘back’ area of the lower, you only need to do a straight shot across the lower.  So the current bolt hold open slot just needs to go all the way over to the right side.


Picture below shows the profiling of the PDQ so it doesn’t push up on the dust cover as much when engaged.
