Microgunner Posted August 25, 2011 Report Share Posted August 25, 2011 and as imschur warned me they won't work on the CMMG Sierra upper without a front sight riser. Says not compatible with railed gas blocks on the back of the package.The crappy Ncstar sights that these are to replace are compatible with a railed gas blocks. I'll order the adapter block that imschur suggested because the MBUS are so much more solid and better looking than the the Ncstars. Quote Link to comment Share on other sites More sharing options...

Microgunner Posted September 8, 2011 Author Report Share Posted September 8, 2011 Riser worked perfectly, nearly. Had to file off a couple thousandths from the bottom inside corner of the left clamping dog. Very minor indeed, I had to study it awhile just to notice it needed this.Co-witnesses with the holosight.

Microgunner Posted September 22, 2011 Author Report Share Posted September 22, 2011 I think I'd move that gas block forward just a enough to get the riser fully back on the gas block. As a side effect, this would also give you a slightly longer sight radius. Quote Link to comment Share on other sites More sharing options...
imschur Posted September 22, 2011 Report Share Posted September 22, 2011 LMAO I forgot I can move the gas block on this without issue...Thanks Quote Link to comment Share on other sites More sharing options...
