The AlleyCat 762 in titanium with a HUB rear end is the flexible option in the AlleyCat lineup. The titanium tube keeps weight to a minimum, which pays off on any rifle you carry farther than the bench, and the 30 caliber bore rating covers the workhorse cartridges: 308 Win, 300 BLK, 6.5 Creedmoor, and the rest of the 7.62 family under the tube's rating.The HUB interface is what separates this SKU from its quick detach siblings. That 1.375x24 rear thread is the suppressor world's universal standard, so you pick the mounting system instead of the manufacturer picking it for you. Run a direct thread insert on the bolt gun, drop in a QD adapter for the gas gun, and swap between them as needed. If you like owning one can that adapts to every rifle in the safe, the HUB version is the one to file the paperwork on.
