"Its an amazing beginner to intermediate M4.

I have been constantly using this rifle for target practice and field play for the last year, and it has held up spectacularly. The rifle can last all day on a single battery. The fire rate and trigger response is amazing. The plastic buffer tube can be annoying, but it isn't horrible. I have been able to use this rifle for up to 200 foot shots with ease. When paired with good bbs and a good optic, this rifle is absolutely amazing. I highly recommend it for anybody looking to get into airsoft.

"Read this before you buy.

I bought the "Black M4A1 | 350 FPS" version.

I used this gun twice on the field and both times it served me well. One of those two times it jammed on me, but the fix was super easy.


-Super high ROF (17 rounds per seconds with 9.6v)
-Pretty accurate
-Easy to adjust hop up
-Trigger response is okay
-Made of polymer, but it's super high quality polymer
-Some metal parts
-Can hold down full-auto for a long time without gun or battery heating up
-Lightweight (could be a con for some, I like the mobility)


-ROF on semi-auto is limited to about 6 rounds per second
-The included magazine's bottom screw kept unscrewing itself and now I can't use it
-Battery connecter is small tamiya instead of deans
-FPS is a little lower than what advertised (for my model). Maybe it's because I shot it alot before I went to the field causing the spring to wear down.
-Tight squeeze for a 9.6v butterfly to fit in the battery space without pinching the wires.

The last con I mentioned actually is a HUGE problem. The small tamiya connector is so fragile that if you're not careful with the wires, the wires will break off the connector, causing the gun to click and heat up when you try to use it. To fix it, the wires would need to be soldered back on the connector. If you don't know how to solder or you don't know anyone who can solder, avoid buying this gun.

Other than the wires attached to the connector breaking off partially, this is the BEST beginner gun out there and would HIGHLY recommend for anyone starting airsoft. Remember, you may want to stay away from this gun if you can't solder.
