I my rifle started out as a RRA A2. I soild the upper to fund a new build. The upper is a 20" flat top. The rifling is poly 3 (3lands and grooves) The group 5 shot was at a 100yrd with Wolf 75steel case. I will see if there is a differents between a poly3 and a 6 lands and groove in FPS. I will post my finding soon.
Barrel: Black Hole Weaponry 20" Poly3 rifling Hbar Upper:Aero Precision YHM Customizable FFT YHM Gas Block RRA: BCG Scope: Tasco World Class 1.5-4.5 (for now) Harris LM-S 
Thanks for looking Culley |
The FH is coming. The cheek weld is ok, I am saving up for a better scope and scope mount. The poly 3 was new for me, BHW 1/8 SS blacken. The company stands behind the product 100% anything wrong, send it back they'll repair or fix at no cost.(other then shipping up there). I will test 3 barrels two are BHW one w/poly3 the second 6 lands and grooves and last RRA SS 1/8 Hbar. All barrels are 1/8 SS Hbar 20". I think that will be a fair test group. I will use the RRA as the control for that is the one most comman to all of us. Here is a pic of both the BHW barrel.
