Just received a 10.5" barrel for a 300BLK build. The barrel I received is for a pistol length gas system and I was expecting a carbine. The upper will be suppressed and on a full auto lower. Any thoughts on the pistol length gas tube opposed to a carbine length?
 
If you're shooting mostly sub sonics you'll be glad to have a pistol length gas system. If you plan on supers it could be either way. More powder options for subs with pistol gas system.
 
Blk will not cycle with a carbine length system on a short barrel. It uses less of a faster powder.
