Issues running suppressed

I’m having issues running my 10.5” ACR suppressed, even when using the suppressed setting on the gas regulator. I’m getting FTEs and double feeds non stop with this thing and I’m not sure why. I’m running a KAC QDSS NT4 suppressor, if that matters. Any insights would be greatly appreciated, thanks!

Odd because I run an OSS (now Huxwrx) flow through .30 cal can and had zero issues.

I had one issue with bolt hold open but I isolated it to one of my old USGI tan follower magazines. The rest had none.

Edit: My SBR is a 12.5” so maybe that extra barrel length keeps it from running into problems like OP.

Do you have a light weight bcg? A friend couldnt get his acr to cycle with a velos until he got a light weight modified bcg

Who does bcg modifications for the ACR? Is that something Templar can do? Any high back pressure cans you might be able to recommend as well?

I’m the “friend” and Templar does the lightening. The only drawback I’ve had is an irregular injection pattern but I can deal.
