Purchased this adapter to pair with the CNC Warrior Bulgarian type 74 brake to go on PAP M90. The fitment so was poor I regret purchasing them both. The M14 side has very good threads, but the detent notches were not cut out enough, or really at all. Took serious filing on the adapter cutouts to get the plunger to engage. Additionally the threads are very loose on M24 side. About ~2mm of vertical play measured with shims on their type 74 device. Very disappointing for both products being made in house.

Results in an extremely loose fitting brake, with concentric play as well as roughly 5mm of looseness on the threads.

I was actually surprised how well this fit - thing sits tighter than any 14x1LH brake I've used, fits so tight in fact that I had to use a little bit of force to turn it so that the locking detent clicked into place. My Arsenal 7.62 74 style brake sits snugly in place, love this little adapter, only one I'm going to recommend
Wish I purchased something else
