Liner nut is right and tight, cap is a-ok and just behind the muzzle of the liner. Talked with Beth at Ruger, she was more than willing to set up the return trip, and then I asked about aftermarket parts I have installed, as before, Ruger wants them to leave in factory form if they work on them. I still have all the factory parts, and we discussed options, she was very accommodating. Before I swap all the stock parts back into it for the return trip to get looked at, I am going to try another batch of ammo, to see if it will do any better. I have some CCI Standard velocity ammo I will run through it.

Just got the Madd Maccs plate for the RMR, and the 1moa RMR is on the way, should be fun when it all works. Thanks again
