I’m looking at ordering a 300 BO barrel for a Lima Six build and I’m totally confused about the gas block journal length needed for a Riflespeed block. 1” or 1.92”? Thank you |

I’ll be going with a .875 for a little more meat since I’m going to run an FRT. Depending on what I can come up with for a handguard, I’ll use between an 8” and a 10.5” barrel. I’m still in the beginning stages of planning though. |
