Have a quick question, and sorry if its a noobish one. I just received my LaRue LT15-12 and have mocked it up to take some measurements, and I noticed that the upper receivers rail is slightly (~.025") lower than the LaRue's rail. Also, I have a Yankee Hill railed gas block (would have been a LaRue if it was offered in a railed .625") that is about .35" lower than the LaRue. I am purchasing the LaRue marked Troy folding BUIS, and am planning on installing the front sight on the gas block over the FF forend, and I am wondering what, if any, risers and other mounts I will need to compensate for the roughly .325" in height difference between the gas block rail and the upper receiver rail. TIA. |
