The Skirmish ECS CA4A1 EC1 M4 RIS is Classic Army's entry level carbine. Utilizing Classic Army's nylon fiber allows for a lighter weight platform while ensuring playable durability in a cost efficient package. The CA4A1 EC1 M4 features a high rate of fire along with a 300rd high capacity magazine so you can put more BBs on target faster than you can count. It also features a 7.5" quad rail system for attachments of lights, lasers, bipod, or forward grip. Front and rear flip up sights are included with plenty of rail space for you to mount a scope. It has a quicker change spring system so that you can quickly and easily upgrade or downgrade your spring once you remove the gearbox from the receiver.

Internally, the gun has a 9mm bushing gearbox, a brand-new electronic control system, inline mosfet protected trigger contacts, 6.03mm tightbore barrel, and a quicker change spring system. Program the electronic control system to shoot at 3 to 5 round burst. Additionally, the ECS has motor protection and low battery detection to help protect the airsoft gun in the long run. It will shoot 330-350 fps using 0.20g BBs and 900-1000 rpm using a 9.6V battery. This model comes with a three prong flash hider that has threads on it to attach a QD mock suppressor. Additionally, there is a flat trigger preinstalled that allows for a quicker trigger pull and response from the airsoft gun.

Product Information:
Bought this gun as a loaner for friends to use. I bought in the California store and they had a special discount available that isn't available online. I an surprised now how good this gun is for less than $200! Super accurate and pretty high rate of fire. It can handle an 11.1v!! This gun is probably the best bang for your buck that you can get!

-Programmable trigger
-6.03mm barrel with rotary style hop up unit
-Great trigger response and rate of fire
-Accurate and good range. About 200ish feet

Absolutely nothing wrong with this gun! Recommend this gun to anyone! Beginners or experienced. You will not be disappointed!

Product Information:
Great gun for beginners, I started with this gun ad had it for a little over a year and i love it. It shoots great and comes with a battery and charger when I got it. Does not look like that the case any more. All i had to do was buy BB's and my gear and i was ready to play.


Hop up replacement
I bought this rifle last year for my first AEG. I need to replace the hop up. How do I know which ones will fit this rifle? I want the best replacement money can buy.

Staff Answer:
Finding the right hop up is a lot of trial and error. Do some research. I would try a MAX hop up or a Pro Win to start with
