I have a 6x45 (6mm-223) upper.
It has a DPMS receiver and gas block
Model 1 Rifle Length Forearm
20" AR-Stoner 1-8" Twist SS Barrel
The barrel is threaded, and the whole thing is extremely accurate.
I am getting .5" or less moa from muzzle to 500 yards.
Check out the 3 shot 200 yard .327" group.
My proudest moment!
This upper has had less than 200 rounds through it,
so it is practically new.
I have around $450 into this upper.
Asking $375 obo.
I will sweeten the pot with a set of RCBS 6x45 Small Base Dies.
The scope and rings are not included.
No BCG or Charging Handle Included.
