The Otter Creek Labs OTB (Over The Barrel) Adapter is the plain one-piece mount for OPS 12, AEM5, OCM5 and OCM6 suppressors: no muzzle device, just the adapter that the can reflexes over. It needs a 1/2x28 barrel that is .75 inch or less in diameter with roughly 2.95 inches of exposed barrel from the shoulder. If you have less barrel showing, the Midway Adapter (1.45 inch) or PTB Adapter covers it; if you want a flash hider or brake in the same part, see the OTB Flash Hider and OTB Muzzle Brake. Raw heat-treated H900 17-4 stainless.
