I'm sure it does run just fine. Why do they offer mid and rifle on a 20" .243 LBC? Because people want it and either will work. Why do the stop offering mid length on a .243 LBC at 22"? Because it's not optimal. Several guys I shoot with who shoot the 6mm Fat Rat and V Fat Rat use it with longer barrels (24 to 27" and one 27" with a suppressor) and +2 gas with great results. You even see plus gas on .223 Match rifles. I'm not saying it is a requirement for a .243 LBC anymore than it is a requirement to use rifle length vice mid on an 18" .223 Wylde but I'm saying it might not be optimal to use the shorter gas path. Where is the gas port on an M1 Garand? Was it a terrible plan?
