The basic QLoader will fit any marker with a feedneck.
Theabove kit comes with the additional elements for an X7 fitting, QLoader sell fitting kits for specific markers and a 'CMS; custom mount as well.
To fit a QLoader you need the following solutions:
1)Feed the hose:
Into a fedneck,
or direct into the breach with a custom solution.
With the Delta either you use the feedneck or you need a solution to direct feed into your breach
2) Mount the QPod receiver - the standard receiver shown is designed to attach with the silver ring fittings to a round vertical grip.
If you dont have a round piece to mount on then you can make/modify a rail mount with a round piece to accept the mount or have a rectangular block* to insert into the QPod receiver.
A CMS receiver can be bought from QLoader which allows you to mount to almost anything
* The pictures below give an idea of a custom mount with a 'rectangular block'
