[Set] Replica DMR E6902M - Black [Golden Eagle] + Scope 3-9x40 with high mount rings [PCS]

Replica ist equipped with an Ares Style ETU, does not accept Gate/Perun/Jefftron Style ETUs.
The Gearbox is a Custom V2 Long in the Sense that it can only accept Normal Lenght Cylinders. So Installation of SR25 Parts (19T Sector and Piston) is not possible.
Externals are nice and Mags are cheap.

I’ve been using this 3-9x40 scope with high mount rings on my airsoft rifle for a few game days now and overall it does exactly what it’s supposed to do. The glass is surprisingly clear for this price range and target acquisition at mid-range is comfortable even at lower zoom settings.

The 3-9x magnification range is actually quite practical in the field — I mostly run it around 4-6x and only crank it up when I really need to confirm hits at distance. The included high mount rings make installation easy and give enough clearance for comfortable cheek positioning, even on standard RIS rails.

Build quality feels solid enough for airsoft use, the body doesn’t feel flimsy and so far it has held zero without any noticeable drifting after multiple games. Adjustments for windage and elevation are responsive and predictable, nothing overly stiff or loose.

Overall it’s a simple, no-nonsense optic that won’t compete with high-end glass, but for airsoft skirmishes it delivers reliable performance and good clarity for the price. Definitely a solid upgrade over basic iron sights or cheap red dots.

Cool scope woud recommend.

“The 3-9x40 scope is fantastic for airsoft sniping. Crisp, clear optics at all zoom levels, and adjusting the magnification is smooth. Holds zero well, even in intense games. Great value for added precision!”

Upon having this DMR for over a year and using it as my primary replica, I decided to rewrite my first review, but as I can not do that, I'm writing a second review.
Standard V2.5 gearbox does not fit without sanding inside of the lower receiver and drilling a new hole for the main back pin in the gearbox.
Lower receiver body is of very soft metal, fire selector is awful, stock wobbles more than on most of AR replicas, but the front part of the stock is somehow so tight so you can't fit electrical tape or velcro tape to the buffer tube to stop wobbling. Stock is large and can take almost any butterfly battery, yet is made in a dumb way so you'll have a problem with wires. Mine also disassembled on its own since the glue break which is holding plastic part which has an adapter for rubber back pad.
Pin on the dust cover doesn't do s**t and it's made of the cheapest plastic.
Magwell on the rear side has groowes so you can not fit a vecro tape when plastic on mags gets worn of. Of course my mags stopped feeding, I've managed to solve it by using maxx 2nd gen chamber (1st gen also had feeding problems on this replica, haven't tried 3rd gen) and putting few layers of duck tape from trigger guard to the magwell. Looks ugly, but it managed to push the magazine a bit to the front so it feed more or less properly.
Motor is useless so ht motor is a must. Screw threads are plastic in pistol grip, of course one of them worn off.
front rail is nice and heavy, but slightly larger than normal picatiny rail so naturally some grips and other attachments don't fit.
Outer barrel developed a wobble which is obviously a big no-no for any replica, especially DMR, I found some thick rubber pad, cut it so it fits inside the rail and use it as stabilizer.
As I mention before, selector switch is horrible. Gears for right selector are bad and give that cheap filing when using it, also barely noticeable click after some time so I replaced the spring inside selector switch and changed pin to a ball, I also deepened the holes on lower receiver for more noticeable click.
Gears are s**t, very loud with that wining sound, but you cant change them because mosfet works in combination with magnet on the gears. Also you can't change the mosfet because selector switch is propriatery and works specificaly with that mosfet. Not sure if different selector switch would work or fit. I managed to pull out the magnet somehow and put it in a spare sector gear which helped a bit with the sound.
Also, spring guide does not have a ball bearing.
Upon assembling the replica its very important the way in which you assemble it, otherwise nozzle won't be align with the hop up chamber since gearbox and body don't fit snugly as in some other replicas. Assemble it like this: Back pin, trigger pin, fire selectors, buffer tube and finaly pistol grip.
I drilled holes in gearbox for 2 more additional screws in pistol grip since with attachments my replica is 5.5 kg, and only 2 screws holding the pistol grip is too few for such a heavy replica.

Final verdict:
Does it work well? After many upgrades yes, I've had hits in game at 90 m with 2.3 j and 0.43 g bbs.
Would I buy it again? NO! That middle (recce) model I like the best in terms of looks, however considering the (very) low quality I would go with 417 assault E&C replica instead.

The scope is very clear. The adjustable zoom works really well to. Setting it up on your airsoft is very easy to. Then adjust the rectangular sight according to your airsoft bij 2 screws hidden under the aluminum caps. Full aluminum, top quality for a small price.

Buy this on sale. I use this on AUG(au-1g j.g. works)
Looks really cool and awesome. Very good materials and zoom.
Plus:
+price
+materials
+strong mounts
+hexagon and small cloth for wiping lenses
+clear image

Minus:
I don't see minuses for this things, for now:)

I would say that a scope is essential for sniping, and this one is amazing. The variable zoom feature is amazing because the enemy can be in different distances, and the zoom feature makes it easier to engage the enemy. It is sturdy and doesn’t rattle, the windage is easy to adjust.

4/5 nothing special but still amazing

Jg or Golden Eagle replicas generally have a decent quality and some proprietary parts of body as well as internals. E6902M is no different. Gearbox is V2.5 by dimensions, however it has a proprietary cylinder head which in total length is 11 mm longer than standard cylinder heads so the cylinder is a standard V2. Airseal is decent, although for a more serious dmr role I definitely recommend nozzle with better airseal (preferably with an o ring). Piston does not have metal teeth so that would be also a needed upgrade. It's incredibly easy to lock it to semi-only: just sand a part of tappet plate which engages microswitch on the left (back) side of gearbox. Problem with my replica is factory shimming, it was to tight and gears have not moved freely as they should so I recommend paying few euros extra for taiwangun service of relubricating and reshimming if you are not comfortable doing it yourself. Also V2.5 is easy to install instead of factory gearbox. Gearbox does have a quick spring change, however lower reciever construction makes it imposible with out removing gearbox from the replica. Motor does not have a nedymium magnets.
Does not have a working bolt catch and as usual with almost all AR-based replicas, stock is a little wobbly.
Body quality is superb.
With normal V2.5 gearbox and decent shimming it would easily pass for 5/5 stars.

The product is perfect value for money. Adjustable focus, easy to mount, gives a clear image. Note that it does not magnify, but adjusts the focus, so close objects are blurred.

Ár-érték arányban tökéletes a termék. Állítható a fókusza, könnyű felszerelni, tiszta képet ad. Arra kell figyelni, hogy nem nagyít, hanem fókuszt állít, és emiatt a távoli objektumok "közelebbinek" tűnnek, de a közeliek homályosak.

Scope is great, it helped me a lot in airsoft games I love sniping and fast moving airsoft games so I bought this scope for my m4 from Taiwangun it super good lens are clear and have great zoom. I hope for this review helped someone who want to buy one.

Scope is compleatly clear, has good eye relief and has adjustable zoom 3-9x it is really useful if you want a closer look on someone, if they are on your team or not. Scope can be adjusted down to 0.1MOA that is 1cm at a distance of 100m. I highly recomend this scope for a sniper, this is a super budget friendly option.

Good one with this price.!!!!!!!!!!!!! 5 Star

A budget sniper scope, that is good looking and great for this price. The zoom on it is simply amazing. Build quality is wery good, and is very easy to mount.
Simply an amazing budget scope to start with!!

Very good gun for an affordable price. It has 3 - 9 x zoom. I use it on my sniper rifle and am really impressed. So far minimum scratches on the outside paint and the lens is clear. It also comes with a protective lens cover so it doesn't scratch during storage.

Amazing scope for a good price! I use this on my Cyma Cm702 platform and I could not be happier. The scope comes with two ring mounts and a bag of hex keys to install it. The scope is not too heavy so it does not add significant weight to the gun (which is an important thing for me).

[Color]

Painted black aluminium, doesnt seem to scratch easily.

[Quality]

Very nice quality and the protective caps help alot!
The magnify is really nice, a bit of difficult to set it up with the screw and unscrew but you can work around with some 3D prints!

[Use]

Overall nice usage on a sniper rifle!
5 STAR for sure !

A good scope for a low cost. The lens goes from 3 to 9 and everything in between making it a great scope in many situations. It comes with a protective caps with also will cut your costs. It does have a yellow undertone but makes the targets beter visible under darker situation.
