The PTS Centurion Arms CM4 C4-10 ERG airsoft gun uses an ERG (Electric Recoil Gun) system that is based on the latest generation KWA AEG 3 system. The ERG simulates recoil via a proprietary Kinetic Feedback System. When used with the proprietary ERG magazine, that is switchable between 30 or 120 round capacity, it is capable of an electrical auto cut-off when the last round is fired. If you are willing to forgo the cut off, the ERG can still use any normal AEG magazine such as the PTS EPM for AEGs. A quick change spring system allows you to easily customize the fps/m/s of the gun to your specific needs. Included as standard equipment for the CM4 ERG, are PTS highly popular proprietary design Enhanced Polymer Grip, Enhanced Back-Up Sight, Enhanced Polymer Magazine and Enhanced Polymer Stock.

"This aeg is truly amazing. Always have an expectation on KWA product but this aeg, KWA made it really nice.
Very realistic feeling, color of the rifle and weight, robust feeling (no wibbling what so ever, but you can feel some movement in the rifle due to the blow back sysem) is really close to the real rifle. Power is really good, shoot around average 385~390 FPS and it reachs 70m and max range is more than 80m if you control your hop up well.

There is one downside which is the hop up system. I mean you cannot get any hop up from this aeg so you need to switch the whole inner barrel, hop up rubber and bucking as well. Which cost me extra 60~70 bucks. But once its fixed you are good to go.
Very accurate and you can shoot all day with this aeg. Just let you know you can't put mosfet nor titan in this aeg...just to enjoy as it is(u know there in't much room for upgrade on KWA's product)
Not the quickest responce but if you don't need crazy like full auto like with semi auto, it is really great aeg.

In conclusion this is not for the game, but for the personal trainning.

Anyways, I really love this aeg.

"Very durable gun, love the full metal. Has pros and cons.
Pros: durable, rugged, very realistic feel and look, comfortable in the hands. Recoil feels great when slinging bbs.
Cons: lower fps(even after checking compression, various bb weights, and cleaning) bolt catch latch broke first day. Very very difficult to get factory muzzle brake off. Heavy, but expected. Will lock up and jam every now and then, throw on full auto, get a round or two out and then flip back to semi and you are good. Hop up is not very responsive to changes.
Overall a good gun and a good purchase. Be aware of FPS problems and occasional jamming. Did okay in the field for first time.
