The new KWA AEG3 RM4A1 Carbine is the first model in the new 3rd gen AEG family. This updated ERG model now shares the newest features of the recently introduced AEG 2.5 system, plus simulated recoil with KWA's patented Kinetic Feedback System. Highlighted by a Switch Life Extender to minimize the wear and tear on trigger contacts, the AEG 3 combines ultimate AEG rifle with a more cost-effective training solution to provide players and professionals the best airsoft experience. Additional features include magazine cutoff compatibility combined with a quick-change spring for users to customize their KWA AEG rifle to their own specifications.

This updated ERG takes the professional airsoft training M4A1 model to a new level of performance with a one-piece full metal alloy upper receiver, a new rotary hop up and a PTS Enhanced Polymer Grip for added comfort. Rear-wired and Li-Po ready, the RM4A1 can still handle the extra power of LiPo batteries. The RM4A1 is also equipped with a reinforced metal gearbox utilizing KWA's unique 9 mm ball bearing bushing combination and case hardened, upgraded precision metal gear sets. Heavy duty spring and a new high-torque motor are matched for optimum results. The KWA RM4A1 Carbine was engineered to outperform, offering ultra high performance and training simulation straight out of the box.

Product Information:
I am a huge fan of KWA products and have been running their AEGs for about 5 years now. I had the first RM4 and loved it. I ended up selling it, and then buying this newer version. Love this gun. The recoil is very cool, especially on full auto. But for me, its the last shot cut off that I really like. Makes reloading a real challenge!



Pros:
Recoil is cool
Last shot cut off is amazing and adds a whole new aspect to playing. Especially if you but the mags on 30 rounds.
Rear wired! The old RM4 was front wired which somewhat limits your possibilities.
Price!!! At $279 this gun is a steal...
Great weight, good accuracy out of the box. Good internals full metal externals.

Cons:
Plastic handguards. Almost guaranteed that you will spend more money to upgrade the front end. But it also helps keep the cost down.
Hop up - its proprietary, which is nothing new to KWA. I have mine flat hopped, but it was a bit difficult to do. I had to actually turn the stock bucking inside out, and sand it down. I could not get the "modify flat hop" bucking to fit for anything...

Product Information:
This is the best balance between realism and playing airsoft! I have owned a lot of AEGs and I own the KWA LM4. Both have their pros and cons. This gun gives me the pros from both and not really any cons. First off the KWA ERG system kicks pretty damn good! It isnt crazy hard, but enough for you to grip the gun down a little more to get your shots on target. Next is KWA has been on the market for a while and has excellent internals. They shoot accurate out of the box and have a great rate of fire. However I did install a r-hopped prommy 6.03mm for better range. Out of the box I think this gun was maxing out at about 220 feet with .25g BBS. Out of the box it comes with the ERG k120 mag. So you can choose 30 or 120 rounds. The magazine has a follower to load every BB and when the mag is empty it will cut off. Letting you know it is empty. When you reload, you have to hit the bolt release to get the gun to fire again. However if you use regular AEG mag, the auto cut off feature will not activate. The gun is a bit heavy but overall I love it!

Pros:
Great felling "recoil".
Great trigger response and rate of fire.
Rotary style hop up unit.
Adjustable mid-cap out of the box.
Uses regular AEG Mags.
Last round cut off feature.
Durability KWA is known for.

Cons:
Weight

I think the ERG system will add a little more weight but KWA bodies are just heavy like no other! Idk why but I have taken a fall on this gun onto a pretty fat rock and it just gashed the side. I thought by body would have cracked for sure. So what you are paying in weight you are making up for in durability.

KWA Ronin RM4 lower with Ronin VM4 2.5 upper
I have a KWA Ronin VM4 2.5 lower and two swappable uppers of different lengths. Would using this RM4 3.0 lower with a Ronin 2.5 upper still produce the kinetic recoil?

Staff Answer:
The recoil is produced by the gearbox, so swapping the lower receivers (and the gearbox that's included in that part) will indeed give you the kinetic recoil.

Staff Answer:
Yes, but you will need to replace it with a different mock gas block to hold the handguard in place, or replace the handguard with some kind of free float rail.

Blowback
Why is there no blowback system on this gun? Is it because it wouldn't work in conjunction with the Recoil system?
