Both the CS3 and the 180R feature versions of the GammasCore bolt system: the 180R with the OP-R Core operating at around 120 PSI, and the CS3 with the OP Core operating in a range from 95-105 PSI. The lower pressure in the CS3 is partly due to its slightly larger body, allowing for more volume in the valve chamber.
Planet Eclipse has released their latest gun, the 180R, the follow-up to the 170R. Although the 180R is quite similar to the 170R, it has been tuned up and tweaked to make it more user-friendly. It launches in a hand-full of colors grey/blue, grey/green, grey/orange, black, and Pred camouflage.
The successor to the popular 170R marker and features one main improvement the, the OP-R Core drivetrain. The OP-R core, is an improved GammaCore with a lower operating pressure.
