I'm selling my complete 300BLK kit as mentioned above.
I'm going the 7.62x40 route with my rifle and have decided to part with my 300BLK barrel assembly to avoid cross-contaminating reloading components.
Complete barrel, QD, gas system and charging handle tray converted and tuned by Dana (Bigdog2003). This is a 100% turn-key package.
I will need the buyers stock charging handle tray as a trade, otherwise my rifle will be out of service. Otherwise, the buyer will have to send their own charging handle tray (with my barrel) to Bigdog for fitting at a nominal fee. Either way is fine with me as long as the traded tray is in equally good condition as my own.
This assembly is unfired by me; the only rounds through the previously brand new barrel were for tuning the gas system on Bigdog's rifle. He can attest to the quality of the build.
This was a 14.5" pistol gas Noveske barrel cut by ADCO to 10.5". The gas port was smaller on the 14.5 as opposed to the 10-10.5" so it was tunable for the ACR.
Price: $750 shipped.
