if you dont know how suppressers work read this if u do them go down
suppressers are a tube with alot of gas chamber in them to capture gas an still let the bullet out
so i resently made one for my bolt action .22 i took a peice of PVC pipe and cut out some cardbord and stacked it up in the PVC pipe and put a bootle cap on the end to keep the cardboard in and taped it off then i put the end not taped off on the gun barrel so it works okay but you CANT used ammo that goes over 1250 fps i think becuase the bullet breaks the sound barrior causing a crack downrange that canot be avoided so use ammo that dosent break the sound barrior
