Pull the muzzle device off and see how it groups without it. If the groups improve alot, that is most of your problem.
When you go to reinstall it use a accuwasher so it can be timed correctly and held on by some locktite and hand tight.
Also I would find a diffrent handguard. Any time you add parts to an attachment point your adding in more fail points. Find a matrix arms handguard it will be non indexing for the gas tube and no shims are needed.
