This pic is a little cluttered, but you get the point.
Magpul PTS PRS in FDE
Leapers illuminated 3-9x40 scope w/ high riser (I have better rings on it now though).
Element brand Noveske 12.5" RIS
Replica AFG in FDE

ARS MASK cylinder head
G&P Explosive piston head
G&P white piston (5 metal teeth)

*Running on an Elite 9.6v 3300mah battery*
*All other parts are stock, however few that is*
Performance: 25rps @ 400fps (very consistant, only +/- 1 on chrono)
I am currently testing a flat hop mod for better accuracy, but Hunterseeker's "patches" may be the better route.
