FPM Gunworks Whisker Biscuit Features The FPM Gunworks Whisker Biscuit is built from 17-4 stainless steel for corrosion resistance and long service life under repeated mounting cycles. A black DLC finish adds a hard low friction surface that resists wear from frequent attachment and removal of a suppressor. The 1.375x24 Bravo thread pattern is a widely used quick detach standard which means the adapter drops into an existing mount system without custom machining. Engineered as a dedicated QD suppressor adapter it is purpose built rather than a generic thread sleeve so fitment and lockup stay consistent shot after shot. At just 1.6 oz the Whisker Biscuit adds negligible weight to a host suppressor while adding only 0.40 inches of length which keeps the overall package compact. It is compatible with FPM Gunworks mounts Q Cherry Bomb mounts and Plan B style mounts giving shooters flexibility across several popular quick detach ecosystems. The black DLC option pairs well with blued or black coated suppressors and hosts for a uniform look while a raw H900 17-4 stainless option is also offered for shooters who prefer an unfinished high durability surface. This small part is an easy upgrade for anyone standardizing their suppressor mounting hardware for sale at GrabAGun.
