For one of my AR's it has always had a gas problem and so I picked up a JP Adjustable Gas System and don't have the tools to remove the muzzle break and get this sucker installed. Anyone got recommendations on a place to take it? For those interested I tend to like slightly odd ball stuff so this is a 16" AR15 upper from CMMG with a rifle length gas system. I live in the Arvada/Westminster area so close is always a good plus.
