Are there any Griffin armament muzzle devices that could be permanently attached to a 14.5" barrel to make it 16" OAL and are bayonet compatible?

The bayonet dual lok satisfies the bayonet requirement, but says it can't be pinned and welded: https://www.griffinarmament.com/dual-lok-bayonet-flash-hider-5-56mm-1-2x28/

The closed tine dual lok can be pinned and welded, but doesn't say it can take a bayonet: https://www.griffinarmament.com/dual-lok-closed-tine-flash-hider/

I know the Gate-lok version of the closed tine muzzle device can take a bayonet, but I can't find an adapter to dual lok for it.

Am I missing something? Or is my choice between SBR that can take a bayonet or pinned and welded with no bayonet? I know the bayonet is kind of dumb considering I'm putting a can on it but it'd be fun to have.

Thanks

I don't think there are because the bayonet mounts go over the barrel and that makes them shorter.

The devices were made for military applicability, so there was no emphasis on 16" permed length.
