I ordered 2 of the DPMS Gen IIs for R&D and really think this might be the better mousetrap in the large frame AR game.
With a medium contoured 20 inch barrel,new MI tube, riser, rings and a 4.5-14 it weighs 9 3/4 lbs.
I only have 100rnds through it but discounting a few short stroke while getting the gas port sized right it has functioned perfectly.
Shoots pretty good to with factory Hor Match 168gr AMAX.
I never could like the full sized AR-10s but this gun handles really well and fits the .308 sized rounds much better. I have some 6.5 blanks rifled and plan on a 6.5 Creedmoor with a fluted 22 inch barrel.
The .338 Federal with a light 16 or 18 inch barrel would also be an interesting thumper.
