[Set] Airsoft Replica EC-901 Advanced Edition (upgraded gearbox) - Black [E&C] + 220rd Enhanced Grip Polymer Magazine for AR-10/SR25 - Black

I bought two of these.
The spring inside stuck after the second use on both mags, even though I was careful not to overfill, and used only BLS premium BBs.
Then, after trying to unstuck it by shaking one of the mags, the spring flew out and the mag disassembled itself as if the bolt and nut at the bottom were not placed and tightened properly. The other mag is still in stuck position as I didn't want to risk a spring in my eye bc of shaking.

Overall, the plastic seems fine, but the final assembly seems poor.

Writing this review after my first game with this replica, I was using 0.32 g bbs and right away I could tell this replica is very accurate, and I was able to snipe many people at a decent range. I absolutely love how the stock and barrel look, which is one of the reasons I picked this rifle + I like the fact that you can only use semi auto, and I can tell you that it didn't disappoint me. Keep in mind if you want to buy this version with this kind of stock to insert the battery you need to unscrew the stock every time which is a little annoying. Of course, being a large rifle with a large stock means your aim speed with it won't be very fast, which is something to keep in mind.

Het is een super fijne replica die netjes schiet ben hier dan ook zeer tevreden mee enige min punt is dat je je batterij in de stok moet stoppen waardoor je de hele stok er af moet draaien op dit moment heb ik een storing in de replica (waarschijnlijk de trekker die dood is) maar naar wat mail verkeer word hij op dit moment nog nageken door taiwangun en gaan ze met een passende oplossing komen

This was my first E&C replica and I have to admit I was apprehensive to what I was buying as I am more used to more expensive brands.
This gun has exceptional quality and finish at a much lower price, and is very true to the original 'real steel' version in terms of physical details as well as being semi auto only. This may be a drawback to some but attractive to those looking for an authentic representation that is true to form and function of the real rifle.
When testing the gun initially I used 'Blaster' .28g BB's with a Vapex 7.4v LiPo and fired a string of ten shots through my chronograph, the FPS was surprisingly very consistent with the widest variance being 1.1 FPS!!
Accuracy was exceptional out of the box too as I was able to land the rest of the maybe 30 shots in the magazine of the same .28g BB's on an A4 page at 30m, and this was all without having to adjust the hop.
One feature I was very impressed with was the lateral adjustment screws on the hand guard, these are two well concealed screws at the front of the hand guard that can be loosened/tightened respectively to 'push' the outer barrel left or right which adds a great amount of lateral adjustment to align the barrel with the iron sight or an optic.
The only drawback I can see with the replica is the battery installation where the entire buttstock must be removed but I can live with this for such an excellent rifle.
Thanks to all the people at Taiwangun for a very professional service too.
