Mod Cricket .25 standard 17.5" ST barrel shooting MK2 at 890fps

Just love how this power mod turned out and like to share the info:

This one has a long forearm stock with Huggett shroud. 28.75" OAL. standard length air tube.



OEM hammer spring was only limited to 840fps, without adjusting the reg pressure and only installing the brass / spring guide weight made all the difference. 



got little more air volume by milling the spacer inside the regulated air chamber.
