Ruger 10/22 Muzzle Spacer 1/2"-28 Thread Steel

Ruger 10/22 Rifles with a .600 long barrel threads require the use of a spacer to reduce the threads to the .400 thread length needed when using a suppressor. This prevents potential baffle damage from threading a suppressor too far on the barrel. It also prevents the barrel threads from protruding into the suppressor chamber, eliminating carbon buildup on the barrel threads that make the suppressor hard to remove. This spacer was designed by Ruger engineers to precisely fit 10/22 barrel threads
