Shot this yesterday. All went well. Started off 4 clicks out from closed. Loaded one (WWB ball)
Got lock back. Went back to 2 and 3 for a couple more singles and the bolt didn't lock back.
Back to 4 clicks. Worked well with WWB, Rem 150 grain, SB 180, a few hand loaded 168 grain, Aussie. F4.
Took ejection path from 1oclock to 3-4. Brass piled up in an approx 20" circle.
Worked both with standard DPMS buffer / spring and sprinco orange / KAK other than a bit of difference in the push not a huge variable. I'm a little torn there, I like a heavier set up. Kind of compared to liking a heavier clutch to a lighter one. Meh, good to know it works with both.
For what it's worth only metering to about 25% of the available gas seems like a pretty gassy gun? I should have measured the gas port in the barrel when the block was off but got tunnel vision in getting it put together and running
The SLR was the icing on the cake if you will. I admittedly think I was in denial about gas. No regrets & appreciate the info here.
