Weight and length of a suppressor can certainly affect the balance of the firearm. Match-grade rifles and ammunition see the least changes. True of both precision rifles and carbines, several recent designs have almost no detectable impact shift. Suppressors constructed with titanium and high-quality designs minimize change. Heavy suppressors have a greater effect, especially on precision rifles. How much again depends on suppressor design, ammunition and weapon choice. Suppressors can cause impact shift when attached to the barrel of a gun. More Suppressor Effects Suppressors should neither be revered, nor feared. You are not going to see any real increase in accuracy, but neither will it degrade. Pistol ammunition just does not provide enough excess gas or heat to cause a problem. With tens of thousands of rounds through suppressed subguns, a quality suppressor has no effect on accuracy even when hot. Since most people do not shoot this way, accuracy is seldom an issue. Shooting a suppressor until it is red- or white-hot is going to definitely cause issues. Significant heat transfer may show a decrease in accuracy while hot. As long as they do not come loose and are installed properly, modern suppressors will do nothing less than enhance a shooter’s accuracy.Ĭarbines under sustained fully automatic fire, or rapid fire, can be more problematic. Less muzzle rise, less sound and less concussive effect also help a shooter improve accuracy. Standard deviation decreases, as a rule, providing consistency, and significant recoil reduction allows you to be more accurate. Modern designs have no adverse affect on the bullet. Velocity change is low to nonexistent and generally increases. Unless improperly installed or attached, suppressors do make shooting more accurate. There is very little downside to suppressing a subgun. Excess gas is minimal with recoil, all but nonexistent. Rifles specifically tuned for subsonic ammunition (such as the 300 Blackout) are similar. A can seldom affects the subgun’s reliability, is quiet and has little adverse effect on overall operation. Subguns are the perfect firearms for suppressors. I have not seen one mounted to a revolver, other than in old movies. Suppressors can be attached to revolvers, but much of the trapped gas just goes out the cylinder gap, lessening efficiency. Low-powered ammunition can turn your semi-auto into a single shot. Some require recoil boosters to ensure proper operation.

Suppressors lessen the recoil impulse required to make your pistol cycle. Rapid fire produces significant heat transfer to the weapon and can have an adverse effect on operation. Excess gas in the action can also affect reliability as the action can get fouled quickly. Adjustable gas blocks help but remain an issue. As a general rule, the shorter the barrel, the greater the effect on the gun’s performance.

Piston-driven systems are less susceptible, but can still be problematic. Increased back pressure causes increased bolt speed and can wreak havoc on function. Most have little effect on bolt guns beyond heat transfer and a sticky bolt that is hard to lift. Suppressors cause back pressure, although newer designs cause much less than what they once did. This will effect your weapon’s operation, and to which extent depends on the weapon and ammunition used, as well as the suppressor’s design.

Suppressors trap, redirect or alter gas expended from a discharged cartridge, both in front of and behind the expended bullet. Suppressors may reduce the report to safe levels, but they still make noise and often require hearing protection. Most supersonic ammunition makes noise that is louder than you think. Centerfire rifles with subsonic rounds are similarly quiet, but are never completely silent. Pistol-caliber firearms are pretty quiet, as are rimfires with low-velocity ammunition. How much depends on many factors: the length of the suppressor, its construction, and the type of weapon and ammunition used. This, however, is not entirely true, as they only suppress it. Perpetuated most often by movies, there is the idea that suppressors eliminate sound. Suppressors Are Not Silent Long suppressors are fantastic for precision rifles-the larger the caliber, the longer the suppressor. Here's the reality of how suppressors are used and what they can do. Author Photo Many perceptions surrounding suppressor effects come from marketing, blogs or the media making them suspect at best. Subsonic ammunition is a key factor in gettting the most “quiet” out of your suppressor.
