[ARCHIVED THREAD] - Gas block selection

Posted: 8/27/2011 9:12:49 AM EDT

I have a BCM 20 inch govt profile upper with standard front sight tower. I want to keep the current handguards, but wish to replace the tower with a gas block. I purchased a Vortex rifle scope to mount on the rifle. Any suggestions as to selection of a gas block? Thanks.

I have a troy low profile on my BCM upper. No complaints. I think I paid $30 or $35 from Rainier Arms
