[Set] BY-817 Short Barrel - Black [Double Bell] + 160rd M4/AR15 Mid-Cap magazine [Fuxing]

I really like the externals, very solid and very clean looking. Honestly that's all I cared about as I was gutting most the internals and building a solid ssg. The gearbox had some excellent compression pieces that are similar quality to maxx, with the cylinder head being something I'd change. The gearbox was pretty beefy and felt very solid but thats all I can speak on how structurally sound it is. The gears and trigger contacts were what you'd expect and nothing too exciting, but I was surprised to see 8mm bearings instead of solid bushing. I still can't say I wouldn't change them or not if you're doing internal work but they seem good enough. My main problem comes from the gearbox shell, specifically where the spur gear is. You will need to remove material from the shell to use your own gears. Now this may only be with rocket 13:1s or all but this can be a minor annoyance. More than likely you have a rotary tool/dremel laying around to easy solve this problem yourself. All in all this is a very solid body to use with some surprisingly good internals for the price tag. I would get this for a cheaper alternative than the VFC version, but if you don't plan on upgrading it then don't expect similar performance out the box. Think of it like a stock king arms or maybe the tier below cyma's platinum line. Other than my small gripe, I would recommend this gun.

That rifle became to my favourite one after the first shots.
I think the best about it is the iron sights. In flip down position they just not disturb you, and if your red dot or collimator have an issue, you can just flip them up, and they enough high to comfortably aim without breakin your neck.
Another good thing is the two side mag release button, which could make the mag change more tactical and quicker in any situation.

There were two probelms: one of them was the dust cover, that made by really weird plastic and most of the time it did not opened if I wanted to change the hop up's position. Other one was the rear iron sight. It have been curved really bad, maybe by the cheap carboarding, but I zeroed it anyway, it's not perfomed really well on longer ranges.

This magazin metalic qualitate is very good.Grip is so gud in my hand. It has a good weight, but not compatible with my Double Eagle M904A replica. Constantly slips out of it. But my friend to Cyma replica perfect fits.

This is absolutely amazing AEG, especially taking into account very affordable price. One of the best value for money acsilable on the market if you seaexh for AR/416 platform.

Pros:
+ Good quality of metal body
+ Light weight metal quadrail (comfortable balance)
+ Rotary hopup
+ Stable performance 1.48-1.5J
+ Bolt catch/ release function
+ good internals incl.metal head and metal sealed nozzle
+ well- built overal & very affordable

Cons:
- stock pad is plastic. No rubber pad.
- easy to scratch- paint quality is not perfect
- High cap mag instead of mid cap in the box
- No Mosfet or at least mictoswitch (fair due to low price)

I played with this gun on the weekend. It has good accuracy and absolutely universal. Can be used in the forest and in CQB.
I definitely recommend it both for newcomers and for advanced players who want to make a custom-built.

well you say 160 but actually its only 95
ive tryed to put 100 in and actually broke the mag so the bbs just got stuck, i opened it to see whats goin on and well , you lied, thats whats going on :/
with the mag open ive put all the bbs i could fit in and counted them, 95 is the exact number off bbs you can possibly fit in one of these and that is 65 bbs less than promissed, i feel disapointed because i bougth 3 of these.

very solid replica, good metal construction, works perfectly fine with 7.4 and 11,1 v baterrys altho the conector type is mini tamya i made a quick change to t-dean and it works just perfect.
no sling atachment point but still easy to fix and that even depends on the sling you have.
the plastic parts are solid the metal parts are good, there is just a lil issue with the sights but if u put an atachment like a red dot also fixes that.

The hole where the bb’s come out of is too small so wont fit fully in the gun(cyma cm.612)Was able to send them back for free bit would have to order a different mag and pay double on shipping, because i dont get a refund for the shipping or discount for the replacement order even though this mag is recommended on the product page. Stay away from this one and order a different magazine!

AEG really solid and well finished. Budget friendly and above average chronograph values.
The only flaws are a ris with a little bit of play (easily fixed) and mine arrived without the motor height adjustment screw.

Silent-play magazines offer a seamless gaming experience with ample capacity. Their durability ensures prolonged use, making them an ideal choice for enthusiasts seeking a reliable and high-performance accessory

The gun is amazing, came in one piece nothing broken. And work amazingly, very responsive trigger when using a 7.4v lipo. Only down side is no sling attachment points, you have to buy a sling adapter plate. Aside from that all around great gun.

I bought 3 pieces from this magazine for a DE-M923G. It fits perfectly into place. It is solid, strong and has a good weight, so it is more realistic. It dispenses the balls well, so far I have not been disappointed with it. 100% how I will buy again. More expensive than cyma magazines, but worth the price.

i buy this to my cyma CM.621 and it perfectly fit. this magazine works perfecly, the feed is good and fast.
I have no problem with the material quality. is durable, i droped sometimes and still works.
I recommend it, but only strictly for Cyma replicas because I heard that it doesn't work so well with other replicas.

Avoid this product unless you have the option to test it on site physically on your replica! I tried it on a Double Eagle M908A and it didn't fit at all. The metal shell of the magazine is not pressed very well and this makes it a bit thicker than standard this makes the magazine to stuck in the magazine well. It's so thight that you have to put a lot force to move it very little. I also tried it on a friend's replica G&G Predator CM16 and the result was the same.
