TBAC Puts SPIRO-SR on Dealer Shelves With a Shorter SR v2 Mount Cutover

Thunder Beast Arms said the SPIRO-SR, the SR-mount version of its Haynes 282 low-back-pressure SPIRO gas-gun suppressor, is in stock for dealer and individual orders in 6mm/.243 bore only. The can uses the new SR v2 secondary-retention mount, roughly half an inch shorter than SR v1, and each unit ships with one SR v2 non-timed brake. Legacy SR v1 suppressors still fit SR v2 brakes, but SPIRO-SR will not mount on older SR v1 brakes. Mile High Shooting and Allen Arms are listed as stocking, so NFA counters now have a production low-back-pressure TBAC fast-attach SKU to quote during Form 3 and Form 4 traffic.
