CORE15-Logo-WHITEBGFor those of you piecing together a new build or just simply swapping out barrels right now, I just wanted to give you guys a quick heads on a promotion that Core15 Rifle Systems is running.  Right now if you purchase any of the barrels on their website they will include one of their new CNC Machined Stress Proof C15 barrel nuts (more info here) for FREE.  No codes or coupons.  Just buy the barrel and it’ll be in there.    I personally own an upper with a Core15 416R stainless barrel and its a tack driver for sure.  Check them out at the link below!
