I get how it goes on now. Sadly the wooden handguard I have won't work with the ring. So I will have to buy new furniture.
I really like that rail. Where did you find it? If things don't work out you have a buyer right here. :^)
Got it off the EE. This is my favorite style KAC 870 ras because it's so sleek. Just gotta buy new furniture for the gun to bring it up to par. Sage stock. I have a mrd for the rail. Maybe surefire foreend or just plain black or wood
