Ate these barrels rated for full auto and suppressed? — 2 Answers
by fitforfamine, from AZ, United States Asked on May 6, 2022
The manufacturer does state that the Quarter Circle 10 9x19mm Barrels can be used with a suppressor but do not state if it is rated for full auto rates of fire. For that information I recommend contacting the manufacturer.
4150 CMV barrels handle all the full-auto fire you can afford to feed it, especially low pressure 9x19 caliber! 4150 CMV one of the most durable metal alloy known! Superior to carbon steel and stainless steel barrels! Owned several NFA Title2 transferable machine guns since early 90s. Haven’t worn out old school carbon steel barrel shooting 9mm in thirty years and beyond doubt you will not wear out 4150 CMV Steel barrel within 35,000+ plus 9mm rounds shot in full-auto mode!
