Use these pieces to convert your Retaliator to use short darts with a 17/32" brass barrel.
The back of the pusher uses the o-ring from the old Retaliator breech. The front of it uses an o- ring from a Caliburn or TC pusher (McMaster part #9452K21)
Pick one of the barrel adapters based on barrel length. I used 5.5" of 17/32" brass and the _Long adapter. Brass slides into the adapter, adapter slides in the barrel lug part of the Retaliator. See pic for how far it should sit but you just want to make sure there is clearance for the darts and the pusher has room to seal in the barrel
_BarrelIndexer is to keep the brass straight in the Retaliator faux barrel.
