I have a question that I was hoping could get answered. I am building a AR Pistol that's going to be chambered in 300BLK, that will eventually be suppressed. I already picked out a handguard, the Fortis Nightrail 10.5" (https://fortismfg.com/ar15-fortis-night-556-rail-system-10-MLOK). I noticed on Columbia River Arms website that they can build a 10.5 barrel for 300Blk. Since I'm afraid that since the handguard and barrel are the same length, there might not be enough clearance when I install eventually install a silencer. I figured I could request a custom barrel build that 11inch for my Fortis Nightrail.
And before anyone ask, I know they offer 12.5 inch, but that would defeat the purpose of doing the AR pistol build with a short barrel.
My question, has anyone built a 300BLK with an 11 barrel before. And what Gas system would you recommend. Should I stay with a Pistol Length Gas system like their 10.5 barrels or a Carbine Length since it's going to be over 10 inches
