DPMS, lower
5.56mm. or 223,
S.S. fluted competition barrel, free floating,
adjustable trigger,
Handloaded ammo, with my Dillon 550B,
Compensating scope for bullet drop,
Built it myself with a bunch of itty bitty parts.
At 200 yards I have a group that will cover about 1.5". As long as I do my part.
