Looks good. Now where do we go to get the grenades?
Even though the grenade launcher is legal in most US States (after a $200 tax, paperwork submitted to the Feds and local LEO), each explosive grenade is taxed and regulated the same way, so its really impractical for the average citizen. Most of the folks that run these type of things as a hobby utilize practice rounds (chalk) or buckshot loads, iirc.
