Beautified my Brn180

Written by Grant on Apr 1st 2022

Didn't see any other choice for the BRN180. Wasn't sure but went w the AB-8R vs 9R and it feels perfect w the mod1 and .25 inch cheek riser. I probably would've gone w the 9R if I was using the folding butt plate. Pieces look and feel better than expected. I also snagged the extended HRD and realized it was too good on another setup. Had to make a few back-to-back orders and shipping was within a day both times.
