I love this folding threaded hinge adapter. I installed this on my YUGO M85 it is very nice well made locks up very tight just make sure to use BLUE LOCTITE #242 on the supplied bolt. I had no issue with a QD SWIVEL fitting it fits tight at first because of the anodizing just push hard on the first install and it will work just fine! I haven't done the drop test to see if the folder will stay locked.

Bought this for my m92 , after installment i tried locating a sling swivel for it .. Turns out it is a proprietary q/d swivel the universal ones dont fit ! And they are never in stock here . after i tried one from a ruger precision that actually fit the smaller hole ( smaller also proprietary ) i noticed my mounting bolt hole was drilled into the sling swivel hole making it impossible to fully seat the ruger q/d swivel ( poor measuring with the ol' cnc ..im a machinist i know ) hoping to see what they do for me to fix this ... For the cost of this compared to other options this should have come with the swivel at the very least as you can buy a complete brace or stock setup for the money this costs

Superb quality and lock up

Installed this on my pap m92 and added a shockwave blade. Easy to install just be sure to get the pap buttstock drill kit. You don't HAVE to but it'll definitely make things easier. Also you don't have to worry about getting a shim because the way this is machined compensates for the angle of the pap 92/85 trunnion. It has a solid lock up and it has good retention when folded down. Highly recommend. Hardware that comes included is the bolt, split lock washer, and the pap carbine buttstock nut. Shipping was super fast!

I just want to speak on how quality the parts and service are.
Before I even received this item I had been on the phone with Tyler from tech at CNC twice picking his brain.
Ship time was impeccable and the install straight forward. Pay attention to similar products out there. CNC's has steel sleeves and alignment provisions. I am a machinist. I appreciate these things.
