View Full Version : Gas System for 300

I'm at the point in my 300 build where I'm ready to grab a barrel. Looking at various sites, all I see are pistol and Carbine gas systems. Is there an advantage to this short of a gas system? I've heard that 300 expends it's energy at 9" of barrel. Does it have to do with that?

Longer gas systems have less dwell time after the bullet passes the gas port and may have problems cycling with sub sonic loads

So supersonic loads should cycle fine with a carbine system?
