Thread: Tape

With a suppressor, no. Without one I always tape the muzzle. It not only stops water but if you poke the barrel into the ground in a fall it stops it getting clogged with dirt. Also stops loose debris falling down the barrel when you are pushing through the bush. Shooting with shit in the barrel will damage it.
I have done a lot of testing on the range shooting with tape over the muzzle and it makes zero difference to POI.
