Some time ago after buying a SR22 I found Twin Tech Tactical out of Texas that had a threaded barrel for the weapon. I purchased one and after many rounds 1000's through the barrel without incident and great accuracy. ~ On August 7, I received an e-mail for John Brady the owner of Twin Tech letting me know about a suppressor they are manufacturing and selling under the product name The Vortec. I am including the content of this e-mail so you are all aware of this new product available to us by a company that produces quality products. ~ E-MAIL: We are pleased to announce that Twin Tech Tactical has developed our own Suppressor. Our new Suppressor is called The Vortec. The Vortec is 1â€in Diameter and 5 Â¾â€ in length, it weighs 5.7 ounces and is rated for.17 HM2 .17 HMR .22LR and .22Mag. http://www.twintechtactical.com/Vortec-Suppressor.html ~ Weâ€™ve been developing the Vortec for about 14 months and have achieved an average decibel level of 114dbâ€™s with bulk ammunition. Weâ€™ve also done some side by side tests with some very well known suppressors with our friends at The Silencer Shop in Austin, TX. The Vortec fell within 2dbâ€™s on average, of one of the â€œHigh Endâ€ rim fire suppressor they sell. ~ Our suggested Retail Price on the .22LR Vortec is $285.00 which is about 50% less expensive than that â€œHigh Endâ€ suppressor. It is currently only available at http://www.thesilencershop.com/ , you may have to ask for it specifically as they havenâ€™t had time to put it up on their site. If you prefer to buy it from your local dealer, we are currently developing a distribution network with Class 3 Dealers nationwide, and you can ask them just to contact us.
