"RIC FLAIR WOOOOOOOOO! That trigger though! I bought 2 on sale for 90 a piece for spares and they both do work! For the price, I was not disappointed!

"First a Correction:
Received mine with a rear wired small tamiya connector. This was a great win for me.

* I am so impressed with this AEG! Price aside, the performance of this M4 is on par with the Lancer Tactical Gen 2 Pro-Hybrid offerings.
* The Microswitch Trigger is the shining star internally.
Because of it being rear wired, taking the handguard and off and punching out the pins on the front sight assembly is a breeze. I was able to have a cost effective 14" M-LOK handguard which is a perfect length for this one piece outer barrel.
* I am very content with the polymer elements of this AEG. My first M4 was alloy and found myself wishing I had something lighter. I ended up with an ARP9 and found I lost serious range. Length of the inner barrel is 14", and effective range is not a problem. Swapped it out with a 6.01 steel inner and a maple leaf bucking with matching tensioner and I didn't find enough of a difference. So I went back with the lighter brass inner barrel and love the feel of this.

- The only con I could find is the regulation flash hider is affixed with strong glue and a solid pin. It takes cutting if you want to be able to remove it in order to remove the front sight assembly. So pick up a fresh orange tip.

"Great weapon for me so far just as a fun gun to shoot in the back yard. Very accurate and feels all around well made. For $80 price range this would be a perfect fit for anyones first AEG.
