You'll need to remove the AT plug and the roll pin that blocks access to the countersunk Allen screw that hold the trigger unit..the drop in reg can be slid in from the front when the fill valve assembly is unscrewed..
Does anyone know how to remove the rear breech screw from the trigger assembly of one of these guns
I want to fit a Huma reg to it
Cheers

Thanks
I assumed there was something preventing access
Does the roll pin need to be drilled out
Can't remember exactly but I think the Allen key will go through the hollow pin and screw will draw it out.... have a look.
