 Product Description


This is our original 3 1/2" SR22 barrel that is ½” longer than the factory threaded barrel. This makes it easier to attach the accessories to the barrel and adds some muzzle velocity. It includes a (3/8”-24 TPI thread protector) but does not include an adapter to attach your suppressor to the barrel.

This barrel will fit Ruger SR22 model numbers 0360003603, 03604, 03606, 03607, 03611, 03613, but will not work on Ruger SR22 with 4 ½” barrel model number 03620.


Please note:

You will need to purchase an adapter to attach a suppressor to this barrel.

For standard 1/2-28 TPI thread suppressors use Adapter Part # (SR22TBA)

  1. Great product

    Posted by Unknown on May 15th 2017

    Dropped right in and now I can use my suppressor.

  2. Quality barrel, easy installation!

    Posted by Ron on Apr 19th 2017

    This barrel was ordered for an early model SR22. I was a little concerned about fit before I ordered but I needn't have worried. The barrel was very well made. The instructions in the Ruger owner's manual and the online videos that I watched were very easy to follow. Easy to remove the old barrel and replace with the Twin Tech barrel. Following installation, I shot the gun both without and with a supressor. There were no failures to feed, fire, or extract. Everything perfect. I recommend this barrel very highly.

  3. Super easy to install.

    Very easy installation. Shoots great. I'm still waiting for my suppressor to try it with that installed. Quality barrel.

  4. Twin Tech

    Posted by Kevin J Kelly U. S. Army MSG (Ret) on Nov 19th 2016

    Excellent product. Perfect fit, excellent accuracy. High quality. TwinTech rocks. TwinTech SR22 take down lever is a super product product as well. Alleves my fear of failure of the original inferior takedown lever. Thank you TwinTech for tacking the time make awesome products affordable. I purchased the SR22 with a non threaded barrel. When I got into suppressorrs, I thought that the SR22 was a perfectly sized rim fire platform to add a can to. I chose the Silenserco Sparrow for my rimfire can and it is an excellent product also.

  5. More Testing To Be Done - Think Its the Ammo

    Posted by Frank on Jun 26th 2016

    Picked up this barrel because I wasn't smart enough to by the SR22 with a threaded barrel. Crazy easy to install. Quality and workmanship are excellent. Value is superb. My ONLY complain and I mean ONLY is that prior to changing out the barrel, I had no FTF or jams in the stick barrel. Now with the new barrel, every time I take it to plink, I end up with a round stuck in the barrel that has not fire. This was not a failure to fire nor a failure to feed. The spend casing was ejected, a new round was loaded but that is where it ends. I have to use the tip of my knife to get it out of the barrel by the ramp. I am using Remington 22 LR Brass Plated Hollow points, High velocity (I know I know, hollow point for plinking...I found them for 7 cents / round.
    So, my slight criticisms are really unfounded as of yet because I need to use other ammo to determine. My guess is the problem is the ammo. Otherwise very confident the barrel will perform flawlessly.

  6. Excellent Fit

    Posted by Unknown on Jun 7th 2016

    The day after I purchased this barrel I ran 500 rounds through it. I was worried about feeding problems with an aftermarket barrel but I had zero. It is a very high quality piece. Fit and finish are excellent. Great product, very impressed.

  7. shoot

    Posted by Unknown on May 27th 2016

    it took about 10 min to install worked great upgrade

  8. Great upgrade for anyone who has a SR22 without the OEM threaded barrel.

    Posted by Mark Santos on Apr 20th 2016

    Easy installation. Perfict fit. My first shot group was tighter than my last group with OEM barrel, without any sight adjustment. The only thing better than the barrel was the customer service. All of my pre-sales questions were answered quickly and with the information I needed. Post sales, fast shipping!

    Great product, Great company, Great service!

  9. Threaded Perfection

    Posted by Edward Coy on Apr 16th 2016

    Thanks so much for this awesome product.
    Installation of threaded barrel take 5 minutes.
    Just what I needed.

    Super quick shipment.

    I've ordered secondary components since original order(captured SS rod and spring and 5 mag extentions for my SR-22).

    Hope your company turns its' eyes on Kel Tec and comes out with an aggressive line of products. If so I'll be improving my PMR-30.

  10. Quick Change

    Posted by Dave Roberson on Mar 30th 2016

    After ordering, the barrel came quickly. Installing the new barrel was extremely easy---remove one screw, remove the old barrel, install the new threaded barrel and reinstall the screw. Done!!! The video on the Twin Tech site was extremely helpful.

    I have put about 200 rounds through the barrel, both with and without my suppressor and had no problems with the performance of the barrel.
