I installed a Troy Ind low pro gas block on an 18" WOA SPR barrel and had to dremel down the gas block a little bit and hammer the sucker on
After I got it all the way down I eyeballed the alignment which looked spot on But, is there any way to check before barrel install that the gas block is 100% aligned on the barrel? Thanks for your help |
