Dmr rifle stock - American Built Arms Company Urban Sniper Stock X

I purchased this stock for a 6.5 grendel build. When I first opened it up and placed it on the Mil-Spec buffer tube there was slack, I was worried that it would not tighten up. Well I was wrong the set screw tightens up very well and takes all movement out of the stock. Once you set the stock to length. If you need a little bit more there is a spring tension adjustment to let the shoulder rest out aprox. 1 1/2 “ this adjustment can be locked in to place by simply tightening A finger screw on the side. This will prevent the stock from moving any.
