"It's been 8 months since I bought mine. I got the half bronze sa-e20 version and it is absolutely beautiful! Lightweight and reliable. With only minor upgrades (bucking and nub), I was able to hit targets up to 200+ feet away with ease in 0.30s!The S-Mag is a wonder and feeds perfectly, and the ease of maintenance is awesome.

-Effective and precise at a considerable range out of the box.
-A lot of battery space on the crane stock, tight fit with the mosfet, but duable. (I personally use a 11,1v 20c 1200mah stick lipo on stock tube).
- lightweight
- Fits all the mags that i have tried on (P-mags, epm and epm-1, standard 300 bbs polymer highcap).
-Easy maintenance and access to internals for cleaning.
-Easely upgradable.
-M90 spring out of the box for cbq fields.
-2 high quality mid caps

-The pins can rust, but they are replaced with stainless steel ones. 
-Trigger jamms if semi-spamming (fixable with gears or another mosfet with active brake). 
-The spring is noisy and vibrates a lot, making an annoying sound, but it is an easy fix.

SOLID Aeg for the price. If you want a good mid tier AEG look no further!

"Had this gun for almost a year now, i only play outdoor and this gun absolutely shreds. My only complaint is some parts of the metal on bolts start to rust but, the performs of the gun makes up for it. if this is in your price range i would definitely recommend.

"had this gun for months and the only issue that occurs is when you finger bang the trigger too fast the gears wont engage and you will have to switch it to full auto, shoot a round and then the gun will be fine again but a simple gearbox upgrade or HPA will eliminate that, looks beautiful and feels pretty similar to a real AR I would def recommend if this is ur price range and need a gun for indoor and outdoor play(the easy spring swap is a game changer)I would def recommend. PS The mags it came with and mlok grip are also 10/10 some of the nicest airsoft accessories I have 0 bad things to say about them whatsoever.
9/10 (rated relative to price)
