XCR with a UBR

[wingshots]

got my dlask adapter today! with a 3/4 cheek riser the CTR lines up perfectly. better cheek weld than the FAST IMO.

Looks good, like it was made for the rifle. And I bet your lop is better too.

Regarding OP's question, the Dlask adapter linked in this thread does not work with the Magpul UBR stock, as the UBR uses a proprietary buffer tube. Because of the UBR's design, it locks into position using a keyway, which the Dlask adapter does not have. The NEA adapter does feature the required keyway, but they can be rather difficult to come across.

Also the low version of the nea works just fine with the scope mounted tight to the rail.
