Item # 261370 Style B&T-SD-SQD-M-45 UPC 840225716344 Condition New Manufacturer [B&T USA](https://www.kygunco.com/brand/bt-usa) Model SQD Caliber 45 ACP Weight 3 lb Action Silencer The suppressor mounts onto the barrel of the submachine gun by simply pressing it over the barrel. The spring-loaded retaining collar will snap down onto the 3-Lug attachment, automatically locking the suppressor into place. The suppressor will remain securely in place, until the operator wishes to remove it. By simply depressing the tab, the suppressor is free to be removed from the barrel and stowed or reinstalled. The all-new SQD-M offers modularity and customization not seen in another submachine gun suppressor to date. The SQD-M comes in one size yet offers a modular RBS-compatible section that can be added or removed based upon end user mission requirements, allowing the suppressor to remain in a full-length configuration, or in a compact configuration, should the user choose compactness over maximum sound suppression. Further, two endcaps are included with the SQD-M, one vented and the other non-vented. These endcaps allow the user the option of turning the RBS off in favor of a sealed system. If the ultimate in sound suppression is desired, the full-length suppressor with the non-vented endcap will provide this. Otherwise, the end-user can choose for themself the size and function requirements to best fit their mission. - Uses B&T’s SQD, or Super Quick Disconnect Tri-Lug Attachment System - Modular design allows for compact and full size lengths - RBS, or Reduced Backpressure System technology in all components - RBS can be turned on or off by way of included vented and non-vented endcaps - A purpose-built submachine gun suppressor offering four different configurations Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service.
