When that gives no complications you are ready for step two which is the upper handguard space but that is another story....
I've already done this and do not have any contact points under the barrel to the muzzle. That's when I noticed a tiny gap under the muzzle so I put the 0.005" shim under the tang and the gap (I have since removed the tang shim). The alternative would be to put a thinner shim at the action screw.

As for the handguard, I guess I can shoot it w/o the handguard and see what happens. If the groups were tighter, then I'd shim the handguard rails, shim the barrel band screws, and reinstall.
