I have a brand new 18” Proof Research Carbon Fiber Barrel. Never been installed on a rifle and never had a round through the chamber. It’s chambered in .223 Wylde w/ 1:8 Twist. This is a beautiful Barrel I bought for a build and decided to go another direction. This barrel MSRPs for $920. This is not a must sell, so please make me a reasonable offer if your interested. Big price drop! Price was $850 and I’m now asking $625 OBO.
