US12650279 - Grenade launcher

A grenade launcher, comprising a barrel ( 10 ), a trigger mechanism base ( 3 ) and a breech ( 2 ) wherein the trigger mechanism base ( 3 ) is adapted to be mounted on a host rail interface ( 1 ). On the opposed sides ( 3 ) of the trigger mechanism base ( 3 ), guide rails ( 5, 8 ) are arranged for sliding mounting of the barrel ( 10 ). The host rail interface ( 1 ) is clamped between the breech ( 2 ) and the trigger mechanism base ( 3 ). The breech ( 2 ) is fitted with a cavity ( 11 ) that surrounds one of the guide rails ( 5 ). The inner wall of the cavity ( 11 ) is pressed to this guide rail ( 5 ) by a detent ( 4 ) that is insertable between this guide rail ( 5 ) and the opposed inner wall of the cavity ( 11 ) that is inclined in a wedge-like way. A pin ( 6 ) bears on this guide rail ( 5 ) from the inner side, the pin being mounted in a sliding way in a recess transversally in the breech ( 2 ) and fitted with a compression spring ( 7 ).
