I've recently purchased a Kalibrgun Carbon Fibre Tactical 2 Cricket. The magazine loading can be a little tricky but you can purchase a Magazine Stop from jb3dpd.com.

He prints a large number of items for various guns and he also sells on eBay.

This is the Mag Stop and my new Tactical 2. The Mag Stop will fit all the Tactical 2 range.

I've also purchased a barrel band, cheek piece, sling swivel plug and decals.
