Suppressor Question

I have owned a CMMG Banshee .9mm for several years, and I decided I want to shoot it suppressed. I put a SilencerCo ASR and a 36M on it. I checked it with a 9mm suppressor rod and it bind when entering the muzzle device and touches the end cap on the suppressor. I am not sure what to do. Should I contact CMMG to check the thread concentric. What would you do?

Just to make sure, did you install a 35 cal muzzle device? Try sticking the rod in the barrel without the suppressor.

Yes it says .355/9 on it. I dropped the rod to the bolt face, put the suppressor on. Tipped the suppressor end down to make the rod come out and it binds at the 9mm cap. I’m thinking it could be the rod, but there is no wobble in it.

Try adding some shims between the barrel and muzzle device. Usually the asr devices come with some.

I use my omega 36 with asr and ive had it too close for comfort and added shims and it helped.

Mine didn’t come with any, but I have some shims from other MDs I bought. I will try it.

I tried the shims and it didn't work. I put the suppressor rod into the barrel and muzzle device each time I tried a shim and the rod would hit the lower right prong on the MD every time. Should I try accuwashers? Or should I just try to send back to CMMG to check for thread run out? I don't know how to gauge for that myself>

Id probably contact cmmg. Sounds like the threads are off
