Thanks so Much Steve,
Very clear directions........and it seems pretty simple to add the END CAP. I like the idea that the gas tube will remain part of the gas block. Sorry, I didn't think that RRA might use their own gas block. It must be a good one because the YHM version requires the "bonding agent" <smile>.
I will carefully index the gas block to the barrel before removal. In two planes .........
Could I ask if there is a torque setting for installing the screws back into the gas block? My tight, may be a little different from everyone elses......or just snugging it back down close enough?
Thanks again, your help is priceless
