Looking at a VTAC 2 point. Since I have a fairly plain jane A2 musket, I know I'll need the buttstock adapter, but I am not certain about the front mount. No rails, and I've got the standard GI issue sling mount. The Viking Tactics sling manual page mentions a side swivel mount, but none of the accessories have the exact name. Is this swivel mount the one I'd need to mount a side swivel at the FSB? Their page itself for them is not exactly descriptive, and I'm not %100 certain what I'm supposed to be looking for.
