Sound Suppressors for Target and Varmint Rifles
What’s better than a 6BR? A 6BR that produces a LOT less noise and less than half the recoil of a bare-muzzled gun. Our friend USMA89 has a 6BR “Texas Tackdriver” with a trued Rem 700 action and Robertson Composites F-Class stock. Smithed by GA Precision, it has delivered tiny groups at 200 yards with 107 Sierra MKs. With sound suppressor in place, USMA89 tells us, it’s like shooting a 22 mag rimfire: “Shooting with a suppressor or can is a great experience. In fact, once you start shooting with one, it is hard to go back to normal shooting. The recoil reduction is amazing, cutting perceived recoil by as much as 70%. Think of a suppressor as the ultimate muzzle break that reduces sound to boot.”
The cost of a good suppressor ranges from $600-$1000, and then there is the $200 to Uncle Sam for the tax stamp and the 3-6 month wait. (Currently, 33 states allow citizens to own suppressors in accordance with Federal regulations.) The suppressor on this gun is considered one of the best, a SWR Omega. USMA89 adds: “I also use a SRT suppressor and am very pleased with it as well. The SRT costs about $300-$400 less than the SWR and you get the same amount of sound reduction.” With a quality suppressor you can get from 33 to 36 db worth of sound suppression.
Once you have gone though the hoops the government has put in your way (check your state laws also!), mounting is easy. Get a good gunsmith to thread your barrel (5/8×24 is the normal class 3 thread) and screw it on. In general suppressed guns barrels are cut shorter for balance. USMA89 explains: “I went with a 28″ barrel and with the can it is a little front-heavy, but the stock’s wide fore-end compensates for this. If this were a ‘tactical’ weapon, I would have the barrel cut down to at least 22″, maybe less. Most people that use suppressors will tell you that they shoot better groups with a can than without. This is because there is less recoil, less ‘dirty air’ behind the bullet, and (in many cases) you get improved barrel harmonics.”
