 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. Excellent barrel

    Posted by Unknown on Oct 2nd 2022

    Barrel installed very easily and fit and finish were excellent. Changed to overall feel to the pistol making it appear to be more solidly built. Accuracy also improved. Have not had to check it with a suppressor yet because I'm still waiting on that to clear.

  2. Nice to have the ability to have a threaded barrel in an original SR22.

    Posted by Scott on Oct 28th 2021

    I've been looking for a threaded barrel for my original design SR22 for many years. I found Twin Tech, but they seemed to always be out of stock. Recently I saw they were finally back in stock and ordered one.

    I just tried it out yesterday and it was great. So nice to be able to have a suppressed SR22! Thank you.

    I will definitely be looking at other Twin Tech products in the future.

  3. ruger sr-22 threaded barrel

    Posted by Rick on Sep 2nd 2021

    I really like this barrel. It shot well with zero hang-ups. Installation was easy and it fit perfectly. It really made the pistol look great. I can't wait to add a suppressor. Buying the barrel was easy and they shipped it right away. I'll be buying fromTwin-Tech again.

  4. Awesome !

    Posted by Fabian R on Aug 28th 2021

    Bought my threaded barrel 2 weeks ago and today a had the chance to test out at the gun range and it work awesome , not only it gives it a cool look to my sr22 but I can feel the difference when shooting. Great price too. I recommend it.

  5. Superior SR22 pistol upgrade

    Posted by Larry Hemmert on Dec 20th 2019

    I ordered a Twin Tech threaded barrel, compensator and adaptor for my Ruger SR22 pistol. The upgrade to my pistol was definitely worth it. Money well spent. Now I need to get the ATF tax stamp and buy a silencer.

  6. Great barrel

    Posted by Unknown on Dec 9th 2019

    Quality product at a very reasonable price. Don’t have a suppressor on it yet but fit and finish are great (way better than factory IMO) and it works flawlessly. Install is very easy.

  7. Perfect fit for early model SR22

    Posted by Dave on Oct 3rd 2019

    I was happy when I got the call from my local gun store that my stamp finally came in for my Innovative Arms Slingshot 22 suppressor. It only took 11 months, lol.

    I have a Ruger SR22 that has been a great reliable little gun and had great potential as a suppressor host, I just needed to drop in a threaded barrel.

    I was disappointed to find out that most of the aftermarket threaded barrels for SR22 pistols only fit models made after a certain serial number range and mine is one of the older models.

    Luckily I stumbled across Twin Tech Tactical. I ordered their stainless threaded barrel for early SR22 pistols and a 3/8x24 to 1/2x28 adaptor.
    The fit was perfect. The barrel dropped right into my gun like a factory barrel. The adaptor fit both the barrel and the can as designed.

    I put about 100 rounds through the new setup this week. The pistol remained 100% reliable and there was no problem putting mag after mag through one ragged hole at 7 yards, which is all I really ask of this little gun anyway.

    The product is excellent, the pricing is very reasonable. Two thumbs up

  8. Looks cool and works great

    Posted by Unknown on Jan 16th 2018

    very accurate and easy to install will know more after a few hundred rounds but so far great

  9. quality product

    Posted by Unknown on Nov 27th 2017

    feed ramp was smoother that the stock barrel, shoots excellent 300+ rounds so far

  10. easy barrell replacement

    Posted by Unknown on Nov 2nd 2017

    product was very easy to install. have not had a opportunity to try out gun yet.
