UPDATE 23JUL2011 245k rounds: After a brief break from airsoft (JAN-MAY), frogfish and I finally got her back up and running. The stock Cyma CM02 gearbox has a screw post at the top-front of the gearbox that is slightly too big to allow the hopup to mate with the feed tube. A bit of filing solved this issue. Internal parts are all stock Cyma V3, minus the Element poly piston, alu piston head, RealSword Type 97B stock spring, and G&P hop rubber. Chronoing 330fps w/0.25g bbs, hitting targets at 205 ft.

I've had nothing but good experiences with my Systema Magnum. Maybe it's this new batch of "Energy" motors that fail?

UPDATE 12DEC2010 243k rounds: after a brief but intense 4k round firefight, through which the gun functioned flawlessly, I began experiencing a very peculiar issue. The ROF would vary wildly from the 1100 RPM it was spitting out (with a new Systema Energy motor) down to maybe 60 RPM... then it would stop firing entirely for a couple minutes. After a brief rest period, it would go through the same cycle of 1100 RPM -> 60 RPM -> only the boxmag motor would wind. Since I didn't really feel like looking into the problem at the time, I switched to my new Inokatsu GPMG, which functioned fl

UPDATE 13NOV2010 239k rounds: finally back from the sandbox! Ran the pig in a couple light firefights, nothing too serious. The gun would occasionally stop firing, which I found odd. I figured I'd wait and take a look-see before the games next weekend. UPDATE 20NOV2010 239k rounds: I found that my wiring harness has a nasty short in it due to the wiring rubbing up against the inside of the receiver. I'll be ordering another new "high voltage upgrade kit" from Redwolf shortly. In the meantime, I'm anxiously awaiting the delivery of my Inokatsu MAG58, which is due in tomorrow.

UPDATE 02OCT2010 234k rounds: my girlfriend ran my pig a couple times over the past few months while I've been away. She reported no issues whatsoever with the Inokatsu gearbox and installed SRC M140 spring. Also had a custom rig made by Ferro Tactical: Specs are as follows: - Split front - Mesh pockets for flotation panels - 2 pistol mag/multi-tool pouch - 2 small GP/beltfed tool pouch - 4 M60 100rd 7.62 link pouches - 4 elastic smoke/bang/flare loops Will review after some hard use.

Same here. Thanks for putting in the hard work!

UPDATE 25APR2010 230k rounds: ran the CM.02 gearbox on Saturday, which chronoed at about 250fps with 0.25s. No issues to report there, aside from the rather silly 1200rpm cyclic ROF. Threw a SRC M140 in my Inokatsu gearbox with the TM piston and Prometheus piston head, then ran that Sunday. Chronoed at a healthy 390fps with 0.25s and dropped the cyclic ROF to a more reasonable 850rpm. No issues to report, aside from the fact that the gun is now incredibly loud versus the previous within-reason loud. I have found an issue with the Arktis rig. It isn't really suited for carrying the weap

UPDATE 17APR2010 220k rounds: the Inokatsu gearbox is not playing nice, unfortunately. Got a new bushing set for it, but now the sector gear is wrecked. I have a CM.02 gearbox from an old AK build I did a couple years ago, so I had that put together with my old Guarder piston and Promy POM piston head. Said Cyma gearbox usually chronoes at about 330-340fps with 0.25g bbs, but it's only getting 220fps with 0.25g bbs in my pig. Not real sure what the problem is, so I'm taking it to my airsmith tomorrow night to have a look-see. I may just throw in my SRC M140, accept the fps loss, and run it

An addendum to the above update: I forgot to mention that my power spring had a slight kink in it. When the airsmith handed it to me, I poked the upper part of the spring, which promptly fell away from the remaining spring. That might explain my power issue from before. Said airsmith is now in custody of my weapon and will be fixing it this weekend while I'm on leave at home. The next update may not come for up to seven months, depending on when I deploy.

UPDATE 13APR2010 206k rounds: installed the following: TM piston (next to last tooth filed) + Promy aluminum piston head Systema M120 Inokatsu high-voltage wiring harness The airsmith tearing down the gearbox noticed nearly no wear on the Guarder piston or stock gears. The only part that had any signs of use was the Promy POM piston head, which was most definitely still serviceable. One of the stock bushings had been worn into an elliptical shape, but the gearbox was still running well. Said bushing was replaced with another from a TM FAMAS that was lying around. After adjusting

Pic of me yesterday holding down the western side of the town. Wasn't feeling too tactical at the time, hence the lack of cover or any real discipline.

UPDATE 10APR2010 205k rounds: installed a Systema Magnum short + Systema chrome-moly pinion, Promy 363mm EG barrel + Guarder clear rubber, and the 250V 30A fuse + fuse box from my Ino upgrade trigger switch kit. Everything performed flawlessly aside from the Promy barrel, which didn't seem to jive with the weapon for some reason. I snagged the barrel out of a broken JG fullmetal M4 to replace it, which ended up working perfectly. While muzzle velocity remained about the same (275fps w/0.25g Fidragon bbs), the Systema Magnum motor bumped the cyclic ROF from the 700s to a consistent 1000

UPDATE 27MAR2010 170k rounds: boxmag began misfeeding every tenth round, causing me some concern. I disconnected the bb feed tube from the gun to discover a sliver of wood being pushed into the receiver's bb tube. Once removed, the boxmag fed flawlessly again. I also wore out a hop rubber, which I replaced with a KWA Gen 1 rubber (all I had on hand). UPDATE 03APR2010 182k rounds: Blew a fuse during the first firefight of the day, melting a hole in the glass fuse container. Tried a 15A replacement, which immediately burned out. The same happened with a 20A fuse. Frustrated, I

A little video from this past Saturday: Myself, my girlfriend and assistant gunner, plus my buddy taking care of business. They hop up and cover my sector when my sh!t overheats.

Here's a couple pics from the weekend:

UPDATE 19MAR2010 160k rounds: overheating problem is still present, although it only made itself known after a 12k round firefight while I was laying down multiple 1000rd bursts. Weapon chronoed at 265fps with 0.25g bbs, which leads me to believe that there may be an airseal issue since the ROF has stayed mostly the same and therefore spring degradation is not a likely culprit.

UPDATE 13MAR2010 142k rounds: wore through a hopup rubber, replaced with KWA first gen M4 hop rubber (all I had on hand). Gun is shooting well again. Overheating problems seem to be gone, although I still plan on replacing the motor again just in case. Carry handle through carabiner method of carry takes some getting used to, but is quite effective and safer than having the weapon slung parallel to the ground, flagging everyone. Low round count for the day is due to 3 other AWs being on the field, lightening my workload.

About 25lbs loaded.
