Spikes tactical 5.56 cold hammer forged barrel with gas block - Spikes Tactical AR-15 5.56 Cold Hammer Forged Barrel

I installed this Spikes barrel (2A8-RTB-CHFMB-SB51606-MLG) on a Spikes upper and lower. It was an easy install, the barrel had a groove cut into it and the gas block aligned perfectly. I used a Spikes Tactical Melonited Gas Tube mid length (2A8-RGT-STMELGTB-SUGT0M3)it also aligned perfectly in the upper. I used a rise armament Nickle Boron BCG (2AL-BCG-RABCG-RA-1011-SLVR). I went to the range today to zero in my scope. I shot at 110 yards Bench rested and was able to shoot 5 round groups and cover them with a quarter. All of these items are 5 star. No feed issues or cycling issue either. Optics Planet has great offerings at good prices.
