I'm thinking about sending in an upper for a front sight base chop and railed handguard installation. When this is done, does the muzzle device have to come off? I have a pinned Vortex flash hider on the 14.5" barrel. If it has to come off, can the flash hider be reused or would I have to buy another one for reinstallation?
Thanks in advance.
ETA- It's a Noveske N4 basic, but it does have the plastic handguards.
