The GSL Multi-Cal suppressor is set up as a complete package to quiet everything from .22 caliber up to .300 Winchester Magnum (GSL part no. MC-100-SUP). GSL Technology ships it with two Bi-lock quick-detach flash hiders, one threaded 1/2×28 and one 5/8×24, so the can moves between a 5.56 AR and a .30-caliber bolt gun without tools. It is 7.75 inches long, 1.62 inches in diameter and weighs 15.6 ounces, with a High Temp Cerakote finish. GSL rates it at 32 dB of sound reduction. It suits a shooter who wants one rifle can to cover the whole safe.
