Threaded-Barrel Bolt Guns In 300 Blackout and 308 Win.
We pitted three well-made rifles from Savage, Remington, and Ruger to see which one was the best to use with a Surge 7.62 suppressor and some subsonic rounds. All could shhh-oot.
A few years ago, the incidence of factory-supplied threaded barrels on rifles was negligible, because most people didn’t have a lot of interest in changing their muzzle devices, including flash suppressors and sound suppressors. Sound suppressors, also incorrectly known as silencers, and more accurately called “mufflers” or “moderators,” just weren’t that common because the devices were regulated by the National Firearms Act (NFA) of 1934. In that law, Congress used its tax power to set up a tax-and-registration system for machine guns, short-barreled shotguns and rifles, grenades, mortars and various other devices, including sound suppressors.
Under the NFA today, a prospective owner must go through a months-long registration process with the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) and pay a $200 tax, in advance, before he or she can purchase a suppressor. Despite the difficulties posed by the regulatory system, suppressor sales have continued to grow over the last decade, and especially the last five years. Suppressor ownership is legal in most states. The exceptions are Hawaii, California, Illinois, New York, New Jersey, Delaware, Rhode Island, and Massachusetts. In the 42 states where suppressors are legal, they are allowed for hunting in all but Connecticut and Vermont, and states are de-regulating suppressor use every day, so this list may be outdated by the time you read this.
Concurrent with the sales growth of suppressors, manufacturers have responded by making the muzzles of some of their rifles and pistols easier to receive the devices. Thus, the growth of factory-threaded barrels, three models of which we recently tested, with and without a suppressor.
