This kit is modelled on the real steel RONI version which converts a standard issue G pistol into a carbine length SMG. This enables you to have two weapons in one: a regular sidearm, and a carbine with this awesome kit! The 'barrel' on the APS carbine kit is a large bore tube so it does not obstruct the BB travel from your pistol in any way. This also comes with a detachable foregrip and a QD sling swivel.
Gun not included!
