Just recieved the new 450 upper in 16 inch. My question is can I mount a standard back up iron sight on the gas block using a yankee hill 1/2 inch riser? will this make it level with the rear sight and give me correct aim? this is a link to the riser.
BTW I am using the magpul bus sights. Yes I do know about using plastic on the front sight block, but this is a hunting rifle, a few shots to sight in and put away so it will not get too hot.
Edit: Also how does the front round handguard come off?
