Well I finally finished my first build. I used a Spikes Calico Jack lower. RRA 2 stage LPK with the ergo grip. I bought the upper from Surpuls Ammo and Arms. It has a Black Hole Weaponry barrel. I still can't decide on what stock I really want so for now, it has what it has. I found the Vortex Viper 2-7X a while back for $150 and used a Burris scope mount. I've been laid up lately due to a back injury so I haven't had a chance to go shoot it. Its driving me crazy. As soon as I can, I will post a range report.
