I'm got started shooting 3-gun this season, and I built a budget AR to get me started. Its basically an M4gery, Spikes lower, PSA LPK, and a Del-Ton upper. I've added a Nordic compensator, and it shoots nice and flat, and drives nails how it is, BUT I think I'm limited a little with the carbine length gas system, and the short sight radius. I'm considering building an upper just for shooting 3-gun. I shoot irons, so I think something with an A2 upper, 18" or 20" barrel, for a long sight radius.
Here is what I am thinking, please tell me if it makes sense:
18-20" barrel, long free float handguard, lo-pro gas block w/ midlength system, and a pinned FSB as close to the muzzle as possible. I'm more comfortable using a front sight that is mounted to the barrel, than mounting one to the free float rail.
Am I thinking about this correctly? Any other options I should consider? I really have no intentions of using an optic any time in the forseeable future...
Thanks ya'll!
