.875 gas block and handguard clearance

[lazyengineer]

I will add - I'm not a big fan of the current fad of very long handguards. I tend to prefer an exposed gas-block for the sleaker profile, weight savings, and access for maintenance. While carbine handguards are too short to really do this comfortably; I find mid-length handguards are plenty long enough. The hardest part is actually finding 9" handguards; everyone makes much longer ones now.
