I can't speak to accuracy for mine (a SOCOM 16) quite yet. I got it kinda zeroed, but that terrible, super-wide front sight had to go, so I DX'ed it in favor of a scout NM sight, which is only a little shorter than the factory SOCOM 16 sight. I haven't yet had a chance to rezero with the new sight. I also ditched the scout rail and got a regular handguard, as I really like the M1/M14 irons. If I do ever decide to scope it or put a dot sight on it, I'll get a A.R.M.S #18. They're a little expensive, but it's my favorite mount by far. I doubt that will happen, though.
I can say, however, that it is a lot of fun to shoot, and contrary to what I'd been told, the muzzle blast isn't really all that bad (though having "artillery ears" may help with that). The muzzle brake that comes on the SOCOM 16 is very effective; felt recoil is less than a .30-30, at least to me. I did a very basic "fluff & buff" job on the sear/hammer mating surfaces, and have ended up with a more than acceptable trigger.
