    Supressor Questions.

    Hey all.
    Just a question, when you take the suppressor off and then put it back on to shoot, does it effect the bullets path?
    What I mean is if the suppressor is wound on slightly tighter or slightly looser. Will that effect anything?
    Or does it make no real difference?

    I wouldn't think so. What is of much more importance seems to be the moisture that can develop inside the suppressor if left on. This seems to increase the risk of rusting and pitting the barrel and suppressor. Someone much smarter than me no doubt will know how it affects aim. I have not noticed any change on my .243 or 7mm08, but we are not shooting any real long range stuff where any small change would be magnified.

    On my Marlin .22 if it's slightly loose it sags enough for the bullets to clip it and you notice it shooting about 2 metres low at a distance of 50 metres.

    The key issue with reflex suppressors (those that reach back past the muzzle) is to avoid having the rear bushing touching the barrel. If it does, you will definitely suffer a POI shift on refitting. Be certain that there is enough clearance cut to avoid this.

    A properly made suppressor fitted onto a barrel where the threads have been made right, the POI should not change when removing and reinstalling.

    However usually there is a POI shit between unsuppressed and suppressed, on many centrefire calibes usually c. 0 - 10 cm at 100 meters.

    Best Regards!

    Some of the rifles I've had & have do suffer from first shot POI differences when installing the over barrel suppressor, then they go back to shooting nicely

    Seems to be more noticeable than my unsuppressed rifles.

    I was always under the impression that they may change and mine certainly do because anything on Or touching the barrel is going to interfere with barrel harmonics?? Is this no longer the case. Those saying they shouldn't shift do they have experience to back this up?? Key is if yours doesn't change points between on and off then you are lucky. I was always told that once you have a Supressor you need to decide what way you are going to shoot. With or without. Remember they can also change the FPS.

    I may well be wrong on anyone of my points above thought but this is from my experience

    In any particular setup the only way to know is to try it out. Fire a shot, remove and refit and repeat. Mad chicken shitting and you might have an issue, I have one rifle that doesn't move much suppressor on off or even loose, but another shifts the POI down approx 200mm and right when can is fitted. Prick of a rifle as I prefer to shoot it can on at the range but useless for can off shooting as anything past about 175m it lobs left and over the shoulder.

    Suspect the can has a misalignment issue, the thing was back to Gunworks for a shell replacement a while back and now touches the outside of the barrel at the rear bush. Haven't been back to SI to get it sorted as they wanted the barrel as well...

    Thanks for all the replies guys.
    Im about to take the gun out to re sight it, so I might take it off and put it back on and see if it makes a change once its sighted in.
    Also, I was thinking of getting a new suppressor for my bush pig .308, obviously opening a can(excuse the pun) of worms but any ideas on what would be a good lightweight one?

    DPT, if you like modular. Theres a couple of other options, but I did see a Hardy pop and spit a shitload of crap back which is less than ideal. They did replace it no question but still rather less than ideal.

    With the screw on cans, it's either tight enough to stay on, too loose or jammed on to the point you can't get the f**ken thing off again. No middle ground unfortunately... The usual recommended tightening technique is run it up tight, back off half a turn then spin it back up tight with a flick so that it's on just past hand tight. Once you have the technique you can repeat it identically every time and that does help with POI changes.
