Ruger SR22 threaded doesn't like suppressor

[bikemutt]

I recently picked up a Ruger SR22 threaded barrel .22lr pistol and took it to the range today for the first time. The gun was decently accurate out the box so I screwed the can on, a Guardian 22. It then shot 4" left and 4" high. I double checked, tightened things up, same outcome. Removed the suppressor, it shot to POA. Put it back on, 4"/4" same as before.

I'm pretty confident there were no baffle strikes after a post-mortem examination. And the accuracy with the can was superb, just not to POA.

I've shot this can with two different 22/45's, 4 different rifles in .22lr and .22WMR and never had it affect POI.

Any thoughts on what's going on here? Ammo was Federal standard velocity bulk. Ruger recommends standard or sub-sonic if a suppressor is used on the SR22.

Thanks.

I have no clue whats happening. I have the Twin Tech barrel in my SR22P, and have a SilencerCo SS Sparrow on it. POI never changes, and it shoots to POA. I would think baffle strikes would occur if things werent lined up properly. A simple eye check thru the barrel with suppressor attached should show if everything is good with alignment. I know its tough right now because of ammo shortages, but I would be interested to know how different ammo would react in your pistol. Aim low, and right...

You had it previously mounted on some pretty heavy guns, compared to the SR22. Maybe the lightness of the gun lets it react more to the change in it's center of gravity.

Same issues

Took my SR22 out for the first time today with my AAC Prodigy. Results were similar to yours, but off the opposite direction. I came home, started researching and found this thread. I've scrubbed my can & have rounded up several types of ammo to test with tomorrow. Like you I have several other hosts & have never had a problem. My thoughts are that it is the adapter from Ruger or possibly the barrel length/ammo combination. If it continues with other ammos I am going to try and get a new adapter from Ruger. I've already looked at the OEM adapter from Twin Tech and they say it will not work on a factory Ruger barrel. My last ditch thought would be to buy the Twin Tech barrel & adapter set. I will add new data as I collect. Bummer to hear others are having this issue!

The Next Day 8/18/13

Shot again with Remington & Federal subsonic. Same results. Shot without can and was dead on. For comparison & curiosity, put my Tactical Solutions compensator on the end and it shot close to those of my can, just not as far off. I then did some close inspection and found that either the adapter or the barrel threading is off. Still can't find a baffle strike in my can or a hit on the compensator. I put my gun with the can attached to a straight edge and it has a bow to the right. Put can on other hosts and shoots fine as usual. Contacting Ruger asap for new adapter or complete barrel swap.

SR22 Pistol Issues continued...

8/23/13

Received new threaded adapter today in the mail and attached it to my gun. Attached suppressor and had the same bow to the right. I've concluded that the barrel threading is off-center. Called Ruger again and they are sending me the mailing info and taking the gun back for inspection.

8/30 Update

Received gun back from Ruger today with new barrel. Attached everything & everything passes the eye test. Shooting on 9/1. Ruger's customer service is outstanding!

 

[baker75jason]

Shoots much better!

9/1

Shot with several types of ammo, with and without suppressor. Variations in accuracy between ammos, but overall is good. Definitely a barrel threading issue... can't say enough about Ruger's service time & help with this!

Ruger SR 22 Pistol and suppressor problem

Same problem here with brand new Ruger SR 22 pistol and Guardian 22 suppressor. SR 22 had vertical stringing without the can but grouped OK to point of aim at 10 yds from a benchrest for a short sight radius gun and cheap 25 yr old ammo. Installed clean suppressor and group shifted 8 inches horizontally and a few inches low. Also had several rounds keyhole. Disassembled suppressor and one baffle had a little lead shaving on it. Installed suppressor on MkIII 22/45 Lite and no impact shift or grouping change.

Guess I'll be exercising Ruger's customer service as well.

 

[baker75jason]

That's too bad... good thing is their service is high quality, so should be fixed quick.

Sounds like the threads are not cut correctly on the barrel.

I tried to put a suppressor on my SR-22 and it wouldn't screw on correctly. Haven't had time to troubleshoot the problem yet.
