Yeah, that and the fact that that length put the gas block flush with the front of the handguard I used. I had to drill another gas port but the positioning of the gas block also covers and seals the original gas port. Kind of a win win deal. I could have welded the original port closed and then dressed it down by hand with a file but it wasn't necessary. Like 98 always says, don't complicate shiit with complicated shiit!😁
