This is a customer provided Vanquish 10.5″ barrel. These are for integrally suppressed builds but the design relies on porting the barrel to bring 115Gr to be subsonic and uses NO baffles. I wasn’t able to hear what it sounds like before doing the modification of adding an extension for the CMMG RDB system or if you wanted to do a ‘single shot’ / ‘bolt-action’ setup with a 5.45×39 bolt.
I will update later with more pictures once it has been assembled and tested by customer.
