Archived [ARCHIVED THREAD] - Front sight base alignment?
Posted: 2/3/2006 4:26:47 PM EDT
I just put a Yankee hill front railed gas block on my rifle,  it lacks index marks or key ways to insure it is strait. What is the best way to make sure I got it on there strait?

I use two of those small bubble levels and use one on the flat top and the other ontop of the front railed gas block and mount the complete upper on a vise or holding it securely on a table top and level the gas block to the recievers bubble level.  I have done this to three rifle barrels and both line up really nice and "trued".
