OK, hinge showed up this afternoon (thanks, Terra!). Got the UBR on the rifle. Pictures will be coming soon (I hope, if the camera cooperates), but if you've seen the pics on arf.com, you'll have seen this (except for the KAC sights my gun has).
First impressions:
It goes on pretty easily, but there's a fly in the ointment right off the bat. This stock is designed for AR15s. It shows in several ways. You're going to see this AR comment a lot.
Firstly, there is what almost looks like a retaining bolt (it's not, not sure what it is) that interferes with the stock going all the way down the spring tube against the M4 adaptor block. It's a cosmetic thing, but it shows you right off the bat this is an AR stock.
Secondly, the additional LOP is a real issue. I like a short stock like most people. The stock is only usable if you collapse the thing fully, or maybe one position out. Like has been pointed out before, if you have arms like an ape you might like this. However,for more normal folks the M4 block brings unwanted additional LOP. Seriously, I don't think you want a folding hinge on this stock on the XCR.
Next up is the width of the stock. It's comfortable, and has a very stable cheek weld. The problem is it sits low in relation to AR height iron sights or optical mounts. My Larue mounts sit too high. This wasn't too noticeable with the FAL stock, but with this one it really comes home. My advice from here on out is to get low Larue mounts. Mine may very well need to be changed.
Lastly, it's heavy. It actually balances my heavy barrel XCR rather well, but it is a touch too heavy for the normal tension of the hinge. Two thoughts here: one is to ditch the hinge and just fix the stock. The other is the XCR needs a locking detent in the folded position like a real FAL. Considering some of the other issues, I'd just ditch the hinge if you really must have a UBR.
Bottom line: it's an AR15 stock and it shows. It's a slick item, but not really well suited for the XCR. Those of you looking for something better than the FAL-style stock probably should wait for whatever Alex is cooking up. I've spent some time looking at this combo and can't help but come to the conclusion it'd be better off with a fishtail style stock like the SCAR. The whole rear stock mount would have to be changed, but I think it'd be the better setup.
