"Putting a suppressor on a gun makes it less accurate." That's the item of firearm lore our Smyth Busters, Brownells Gun Techs Caleb and Steve, tackle today. Is it true? Not exactly, says Caleb. Simply installing a sound suppressor on the gun WILL NOT affect the gun's accuracy. In fact, some suppressors, like Area419's Maverick, are made specifically for long-range precision rifles. If you had to thread a previously un-threaded barrel to mount the suppressor AND goofed up the thread job, then yes, accuracy can be compromised. But it's messed up because the misaligned threads have led to a misaligned suppressor. You'd get the same results if you installed a muzzle brake, flash suppressor, or compensator on misaligned muzzle threads. Use an alignment gauge to make sure everything is centered correctly. And if you're mounting a suppressor on your AR-15 / AR-308, heed Uncle Steve's warning to use shims to time it, not a crush washer.
