they have to cover their arse because they have no idea and can't predict what somebody is going to stick on the end of the rifle, or if that somebody is smart enough to turn down the gas and/or run a smaller jet.Well. Hey if it’s suppressed and breaks? If they give you any crap? Who’s fault is it? I mean is it ok to put an oil filter on the front? Lol that’s kinda like putting headers on a car and tuning it. Factory doesn’t have to acknowledge if that’s what caused the issues.
it doesn't mean the rifle isn't perfectly solid or reliable with a suppressor.
