Don't hold your breath on a SR/Hellfire mount. As a rule we don't want to make mounts that latch into ratchet/QD systems. The stacking can get a little funky, and we also see a reduced utility. The SR seems to be a really terrific mount system, and was designed for hard-use like full-auto. Stacking one of our mounts into that system wouldn't be ideal, as out mounts aren't ideal for the situations the SR was designed for.this is what I did.
338SR and DominusSR
if only A419 would make a sidewinder adapter for the SRs
I just changed my order from a SR to the CB Dominus yesterday. Now I am considering canceling the 1/2"x28 brake and going with the Area419 Hellfire system. I already have 2 Hellfires and would need 3 more adapters to swap the Dominus between several rifles. Also have a 30P-1 that I am considering the recore. I could slap an adapter on my Harvester and be set. Getting a serial number assigned next month. (Buying with a cert)I went the opposite direction, 338Ultra and Dominus CB, because Area419 makes sidewinder and hellfire adapters adapters and I didn’t want to be handicapped
to the TBAC SR brakes.
