Took my pesky, high-right shooting Bushmaster M4-style rifle (http://www.mdshooters.com/showthread.php?t=38228) to Hap Baker on Saturday. After much wailing and gnashing of teeth, it now shoots pretty much where I aim it. I remounted the carry handle and adjusted the rear sight as far left as it could go. Adjusted the front sight down a smidge as well.
I did notice that the rail on the upper is ridiculously tight. So much so that when I tried sliding a friend's A.R.M.S. BUIS it took a Herculean effort to align it with the rear notches. On his Rock River upper it slid on like a buttered bull moose. And again, my shots printed way right until I dialed the rear sight all the way to the left.
The laser boresighter I used to get my friend's Eotech HWS dialed in at home put a nice red dot off to the right as well. Is this an indicator that something ain't right with the barrel? With the upper rail? Or perhaps that I remain more stupid than I'd previously thought?
