I fell in love with the helical mag concept of Calico weapons, but have been somewhat let down by the design execution. The Liberty carbine has always been a bit off to me, with a mag butt in my cheek and a horrendously long reach to the grip. I have begun a series of design changes, the first of which is to make the magazine into the cheekpiece, as below.


The next generation will most likely be completely new, placing the mag in a bullpup type configuration, although custom 75rd mags may be needed to keep length of pull manageable. This will keep the barrel closer to sight line.
Third generation will be an NFA weapon, with shotgun secondary.

And before anyone else gets to it.......
