@trophyhunter Did you know proof is selling 6.5 prc barrels for the AX? It’s on their website
Accuracy International Pre-Fit barrels
Pre-Fit Accuracy International barrels are quick and easy to install on the AI platform and require no specialized gunsmithing.proofresearch.com
AWM uses the same M27 tennon as the AX/ AT/ AW's.
So, it may be for that rifle and not actual short action ones....
