Anyone using one? Some stands I use and could use are close enough to residential developments that high powered weapon noise could be a potential problem to the landowner and then my use of that area. I've looked into firearm suppressors of various designs and cost which would include having to machine my existing rifle or find some existing unit that uses some sort of clamp-on system.In any case they are expensive plus the permit cost. I'm wanting to find out if others using suppressors think their results justify the investment? Thanks!
