    5.56 suppressor on a PS90 SBR???

    What do I need to know? Should I not do it? Are 5.56 suppressors too heavy to allow the barrel to move correctly? Will I get lots of blown cases out the ejection port as a result? Am I better off using a 5.56 mini vs full size? Will my stock crack and break? If so, how long can I expect it to last?

    Or should I ignore the internet rumors because they suppress fine with 5.56 suppressors?!?

    I have used an AAC Evolution 9, a Saker 5.56, and now a Gemtech SAR57 with no issues due to the floating barrel on the PS90 SBR.

    I have not heard of any members having any problems using a can on the PS90 SBR. Now the only issue I know of is with the FiveseveN because it does not like heavy cans, so I think that the weight limit is somewhere around 12oz for the can.

    Shoot it and have fun.

    I run an old Huntertown Arms 22 suppressor on mine - works like a champ - probably 500-1000 rounds through it. Honestly, they don't need much - don't think I'd bother with a 556 suppressor - just over-built and heavy. Love the platform because it is light, compact and intuitive. Matt

    Most people probably run 5.56 cans but as SD9 said, almost any can will work great and be hearing safe. My favorite may be a 3 lug 5.7 can...picture the GT can with a 3 lug mount.
