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.
That's the wrong way, the handguard has a task also, compare it with a garden hose, when you hold that one some 8 inches from the end loosely the water goes everywhere, now hold it that same way some 2 inches from the muzzle and see what happens....
