    Crush washer or shims

    Iím thinking again, been thru this in my head on the last build. As Iíve read and it somewhat makes sense. Is the crush washers do not align the MUzzle device perfectly and can cause slight accuracy issues..Iíd say not all the time, but maybe certain MDís?

    So for a non suppressor setup , ie: flash hider, comp etc..

    Crush washer or shims?



    Lol..ya Iím overthinking again...blame Alamo partly......that and just striking up conversation

    Its usually manufacturer specific, some call for a CW and some use shims. Which MD are you going with?
    The best way to survive a violent encounter is to be the one inflicting the most violence.

    Shims or peel washers are better in my opinion. That said a crush washer won't hurt at all. For an average shooter your inaccuracies will be way more about ammo than muzzle devices.

    Basically if you strapped down a gun in a vice and had perfect rolled hand loads you MIGHT see a difference but with off the shelf stuff it won't matter.

    I like to time everything, there is always a top and a bottom. They aren't cheap to start, but I really like the Accuracies-Washer system.

    Sometimes timing can get you different results. I didn't time my Griffin MD at first and with the can my POI was like 4 or 5 inches vs without. When I timed the MD correctly the POI shift went to about 1 inch.

    Basically read the instructions and if it says time it then obviously do it right.

    As you correctly pointed out with some MD it does make a difference.

    For the rack grade rifle with an A2 comp or something similar that should be timed, a crush washer. A lock washer for an A1 or similar. Shims if it's a precision rig that you're trying to squeeze as much accuracy potential out of it as you can. If the manufacturer has specific directions, follow them.

    I generally use these:

    But mainly because I have a whole bunch because GA includes them with their MDs

    Yes, they stopped making that style. They did just introduce another new style with their Explorr suppressors that is similar:



    I think I have a spare birdcage in .308 if you need it.
