37mm to 12gauge Cartridge Adapter

37mm Cartridge Adapter

These aluminum adapters will allow for the use of 12 gauge flares, blanks and signaling rounds in your 37mm launcher.  They are bored to a depth that will not permit the loading of a full sized shotgun shell.  They WILL seat ALL of the 12ga. signalling rounds and blanks.

NOTE: ATF takes making a firearm without having a license very seriously. Using real ammo with these adapters thru a modification of them can create severe criminal liability. Be aware.
