Can the front sight be moved back so a moderator can be added?
It certainly appears to be movable.
Echoing the question from Ryan, and more: Can any one tell me what inserts are compatible with the front sight? What sizes are the front and rear apertures as delivered with the rifle? Does the Air Arms Front Sight Inserts, 4ct item, item # Air Arms Front Sight Inserts,..., offer larger or smaller inserts? I need to see more of the target, so would like a larger front aperture.
What rear sight did your 2078 come with, peep/aperture/diopter or open notched blade?
I received mine yesterday evening, and it came with both! (neither attached to the rifle).
How is the CO2 tank filled? Does it take 88 gram cartridges, or does it have to be filled from a separate reservoir with a hose and connector?
This one uses 12g capsules. If you want to bulk fill, look into the ar2079a. They make an adapter for the 88g.
Can any one tell me what inserts are compatible with the front sight? They are supposed to be a copy of an old auschutz design. Where to acquire?
