I had a blip with my apc223 and a Larue QD mount my aimpoint is attached to. I had to really squeeze the heck out of it to get on, and then could barely get it off. No problems on other pic rails.
But I have a nightforce 1-4x that is also in a Larue QD mount, and have no troubles with that (is goes on so easily it’s almost loose).
I was blaming the Larue on the aimpoint, but maybe the rail spec isn’t perfect. I’ll explore more tonight with a caliper

B&T rails are just a tad larger than 1913 picatinny profile. Yes, loosen nut opposite rail clamp adjuster on AMG UH1. Try it a couple of times to ensure it fits tight.
Lmao spoiled? Please tell me what part of that sounded spoiled? No the apc223 is certainly not my first rifle and I baby my #### hence why I didnt want to put force into the QD before asking first, is that not what forms are for?
Again I have loosened the retaining screws as far as they will go, they have reached a point where they do not go any further.

Some optic mounts simply won’t work on certain B&T models because their pic rails are not to spec. An example I ran into was Scalarworks mounts on the GHM9, and some report that Eotechs won’t fit either. If it goes on, the QD will become extremely not-quick detach, and it’ll probably scrape off some paint getting it on in the first place.

The fit is tight but not impossible to mount optics. I run Aimpoint T1’s, ACRO’s, Elcans and Trijicon MRD’s on all my B$T rifles. I use OEM mounts as well as scalarworks and KAC. By adjusting mount clamp, they will fit. I’ve had similar issues with HK MR’s rails as well as SAN rifles in past. European STANAG specs are slightly bigger than 1913 picatinny. Not a show stopper though.

For whatever reason, I just (wrongly) assumed, you were some noob, who "daddy" just bought a first rifle, etc, and you didn't know how to use a picatinny mount properly. I know there are A LOT of spoiled "rich kid Markham kids" who are literally showered with toys, guns and gear.
I guess low-key a bit Jelous I am?
Just goes to show you how the age old saying "assumptions make an Azz out out of you and me" .
Had no idea that there was fitment issues common to B&T, and would have never guessed that.
Sometimes it's best to keep quiet, instead of making a fool of one's self. OOF.
My sincerest appologies. I take back my original comments. I jumped the gun on my assumptions.
Have fun with the APC223!

the Vortex UH1 looks like it uses a take on the old-style American Defense quick release levers. The screw on the right side has a spring loaded detente that pops into the flutes around its perimeter. The screw should completely unscrew for disassembling the mount, so it shouldn't get 'stuck' unless it's bottomed out on tightening it (Not implying this is what's happening, but that's the easiest thing to check for)
You'll want to 'unlock' and open the mounting lever (all the way open) as if you're going to mount it, then unscrew the adjustment screw. The detentes might be a bit tight as the screw turns, you can try pushing the whole lever assembly into the sight (the old style ADM mounts wouldn't let you do this, as they're retained by a snap ring) if it seems like it's getting stuck. the NEW ADM mounts do let you push them as that's how you actually adjust them....
Once it's open enough to pop the sight onto your rail, and tighten the clamp screw, you want the quick release lever to start making contact at about the 45 degree (from being fully closed) point, and from there you can tighten or loosen it a click until you get a good clamp. I'd lock/unlock it about 10 times to get it to set in, usually once you break in the QR lever it needs to be tightened by 1 click.
If it's completely stuck, the spring detente might be damaged or jammed, the thing should have a good 1/8th inch of adjustment side to side.

There is no issues with the rails. EU specs slightly larger. I have several APC’s and all same and I simply opened up the clearance on my optic by adjusting detent ....Vwalla! What’s the first thing you say when yuh can’t figure something out? “THIS PIECE of ####”!
In reality....operator error
