ICS CXP MARS Carbine 3S EBB.3 burst and diagnostic gearbox version.Bought during lockdown and hardly used.Some marks from use but as expected.Incredible consistency as shown,chronoed today with .25’s which equates to around 345 fps on .2’s.Unmolested apart from a mod to the stock to allow a bigger battery to be used,doesn’t affect use.Only selling as I just bought a Krytac and hate to see my guns laying dormant.Original box but nothing else supplied.Postage and all fees are included in the price,obviously collection or a meet will earn a discount.
