The RM4A1 ERG Recoil Feedback AEG is an amazing product from KWA, utilizing their patented KFS (Kinetic Feedback System) to simulate the recoil of an actual firearm. It is designed around the concept of being a potential training/simulation weapon, and has many features that compliment this idea. Alongside its felt recoil, produced by a weight in the stock similar to a buffer in the real AR platform, it also features an electronic and mechanical cut-off produced by using the RM4 magazines that utilize an extended follower spring. When reloading using these magazines, you will have to use the bolt release on the side of the weapon to "release" the bolt, allowing the rifle to fire again. These magazines can also be switched between 30 and 60 round capacities by a simple switch hidden inside. And if you are not partial to this feature, this AEG is compatible with TM style M4 magazines as well, while retaining its recoil. This gun is designed for the output of an 11.1v LiPo battery and features an internal quality that represents this, with the KWA 3GX gearbox, a rotary single piece Hop-Up, 2G bucking, low resistance wiring, and KWA's well known reinforced gearbox internals that allow this weapon to be reliable under the heavy load, while still producing a respectable 14+ rounds per second fire rate. This rifle is also backed up by KWA's 45-Day manufacturer warranty.

5 of 5 Satisfied Customer April 15, 2021
Reviewer: William Jenkins  
I ordered this airsoft rifle from a competitor, whose website indicated they had this rifle in stock. After a week I received an email from them alerting me that they did not have the rifle in stock. I immediately checked their website, which still indicated the rifle was in stock. After a few more exchanges with no progress I cancelled the order. I then checked the Airsoft Rattle website, which indicated they had stock. I immediately called them to confirm, which they did. I placed the order and the shipment was out the door that same day. I had my shipment within a week. That is terrific customer service! Kudos to Airsoft Rattle for knowing how to service their customers.
