Ever bought a Airsoft M4A1 Long Carbine 1(Like the G&G Raider L FOR EXAMPLE) and didn't want a suppressor extending the length of your gun? With the OBS Suppressor, you can now cover that long barrel with a suppressor that goes over barrel and threads onto it meanwhile covering the entire barrel and now you have a suppressor without having to have it sticking out so far! Threaded at CCW -14mm standard. It also fits into rail systems similar to that of the suppressor for the Honey Badger!
