Summary 260mm in lenght, this supressor is available in two smaller pieces. It's designed to fit the 23x1 CW thread on the barrel. Can house an extended inner barrel (up to 10mm diameter) In case you want a shorter model, just shrink the Z size on the half without the barrel threads. Edit: Also uploaded 14mm CW and CW versions, so you can use anywhere you want. Edit 2: Added the V2, for the L96 (Mk98) with barrel support.
