just finished this on 4-1-10 now it off to break it in. This rifle came to me ordered from DPMS as an LR308, I had them replace the upper with A3, blk teflon bbl and the gass block to the low profile. I added Troy 13.5 inch rail and magpull butt stock. I cut the barrel to 21.5 inch,recrowned and threaded it to 5/8x24. The pistol grip is on back order. During 24 round break in I got a 5 shot 5/8 inch group I have posted in another thread. The scope is a MK4 M3 with NF rings.
