Below is a pic of a Whisper upper I bought used. I have suppressed it, but it is making alot of noise from the gas block area. It cycles subsonics as weak as 175gr SMKs at 925fps no problem, as is. However, I taped a sheet of white paper to the inside of my free float handguard, and after shooting several rounds, noticed black streaks on the paper. Obviously, gas is escaping from around the block. It appears to mostly be coming out from where the gas tube comes out of the gas block. There also seems to be a little leakage in the front of the gas block. I plan on shooting supersonics through it as well, so I'm going to need an adjustable gas system.
My question is should I replace the cheapy gas block with a JP Adjustable gas block? Or should I replace the tube with a Fulton Armory adjustable gas tube and then seal off the areas where gas is leaking? My friend said to use JB Weld all around where the block meets the barrel and around where the gas tube goes into the block. I was thinking of 'sweating' the area with solder like you do when you are fitting copper pipes.
Any help or suggestions are appreciated!
