Got some nice weather today so dropped by the range. No problems whatsoever, bolt locked back on all magazines (D&H) no failures to feed or eject. Final settings on gas block (SLR Sentry 7 Adjustable) about 1/2 way with empty's landing apx. 6' away @ about 2:30. Brass looks great, no dings, scrapes or ejector marks.
I drilled the gas port to .093, changed out the Aero carbine recoil system to the Griffin Maritime AR10 setup and had to install 2 quarters to make it 7 5/8". I also upped the buffer to 5.7oz from 4.9oz. With the VG6 Epsilon muzzle break and a Limbsaver recoil pad on the Magpul STR stock evrything just purrs right along.
I thank you all for all the valuable input, the plan came together smoothly.
Todays testing was done with 308 Win 150grn FMJ, I'll most likely have to adjust some things when I run the better ammo. For now I'm pretty stoked!
