This might be a niche topic, but any Remington RACS chassis owners that have a RRS BRACS ARCA plate? I placed a custom order to have a run of the BRACS plates made, and they do not fit properly on my short action RACS with a full length fore end tube, nor with a spare XM2010 fore end I also have (both fore ends are the same).
It looks like the curve of the mounting screw points on the RRS BRACS is sharper than the curve on the full length fore end tube. Sliding the BRACS all the way back pushes it down a bit, causing the mounting screw holes to go out of alignment. So I can only push the BRACS so far back before the screws start binding due to the misalignment. Please see the below pics for what is happening.
