VFC gas block fitted after much swearing. It's not a direct fit and took a bit of filing, bashing etc to make it work.

Battery extension printed and fitted.

sorry mate, tell your wallet I'm sorry!

I agree. Normally when I review airsoft guns there is usually some soft of negative point but I'm finding it hard to find anything slightly wrong with the DE I just reviewed. I think that if all the DE models work as well as this then the big boys are going to have to step up to compete.

I forgot to mention I used 4 differnet brand/type of magazines and didn't have any feed issues with any of them. Supplied mag - good Hicap Pmag - good Midcap Emag - good Lonex fast mag - good

lol..that teaches me for rushing

So I tested the AEG today using various weighted BB's and the results are: 0.2g upto and including 0.28g no problem with hop or overhop 0.3g upwards don't hop. I'll probably run 0.28g BB's until I get around to S hopping the inner barrel. If you buy 1 and want to run heavier BB's then you will need to look at another hop rubber/bucking/hop unit to run the heavier BB's. I also tried to measure the inner barrel as I'm curious to see what the inner diameter is however I ran into a couple of snags. The first being the flash hider. The grub screw that holds it on and the flash hider actually have thread lock on them. I wasn't expecting this for such a cheap AEG and is something normally seen on high end AEG's. I had to end up press fitting a star drive bit into the grub screw to get it out and used set of pipe pliers to get the flash hider off. This sounds like a negative but its not. It just means the build quality coming from DE is pretty high. You can see on the picture below the red residue of the threadlock on the inside of the flash hider. Once I got the flash hider off I used my calipers to measure the inside of the inner barrel and got a weird reading of 7.4mm as I pushed the calipers in further it got smaller 6.4 until I couldn't fit the calipers in any further. It turns out the inner barrel has a taper for the last 15mm of the inner barrel. Again this came as a surprise on such a low cost AEG. I haven't stripped the gearbox yet but I did find this good photo on Taiwangun showing the internals. I've pretty much set on this layout for now (apart from a 3D printed battery entender which is printing as I type this). If anyone is interested it's now £104 on Taiwangun and this is a mental price for such a good little AEG. I'm tempted to go buy one of the longer models as I think this whole series from DE could be very good value for money. *EDITED as I don't know which way a red dot goes on a rifle

I did a quick field strip and found tha the gearbox is a quick spring change version but it's anything but quick change if you don't have a very long 4mm allen key. I had to jury rig something to get it out. This is the offending bolt. I wish they had used a normal star headed bolt. Getting the spring out is easy one you get the stock pipe off. I swapped my spring for a Modify S90+ and now I have an FPS of 310. I might try a S100 to see if I can get close to 345. The hop unit is plastic but seems good enough for the job. I'm going to try a few differnet BB weights tomorrow to see how it handles up to .36g

don't know yet as I haven't stripped it that far. it's on my to-do list

A brief history of the RS Honey Badger. Developed in 300 BLK ammunition for the replacement of the US SOG MP5 SD range however it was never adopted but AAC and then Q went on to refine the Honey Badger and offer it to the civilian market. Currently the range includes an SBR, Pistol (actually an SBR but with brace instead of stock) and lastly a suppressed model. The Double Eagle M904G. Double Eagle is normally a name I have shunned as they have made some pretty bad, low powered airsoft guns over the years and it would take a lot for me to even consider buying anything from DE. When I saw the new M904G from DE appear on the Taiwangun website I almost overlooked but I thought I’d have a closer look at it seemed to be a good external copy of the real Honey Badger. After looking into DE’s offering a bit more it got my interest when it claimed it had an adjustable trigger, Mosfet as standard and claimed to be able to binary fire out the box. For info Binary fire is the latest crazy in the US RS market where you get 1 round fired when you pull the trigger and another round off when you release the trigger. I have a mate in the US who has built an SBR in .45 with a binary trigger and it’s mental to fire. Another selling factor for me was the price. DE are offering various models and the M904G can be had for £106. That’s right, an AEG with mosfet, binary trigger, hair trigger and adjustable burst fire (1-5 rounds per trigger pull) for 104 quid. It’s either going to extremely crap or extremely awesome at that price. So after ordering and waiting a few days the AEG has turned up. It’s packaged inside a nice box with foam protection. Inside the box you get the AEG, Hicap magazine (300 rds), cleaning/unjamming rod, a wind up key for the magazine (also has the standard wheel on the bottom to wind if you want), a spare Deans connector, a Deans to Mini Tamiya connector, a decent manual and a Mosfet setup guide. The rifle is made of polymer apart from the outer barrel, Flash hider, Gas pipe, Fake bolt cover, sliding stock rails, part of the magazine catch, charging handle and the nuts and bolts holding everything together. The polymer used is very thick and has no wobbles, creaks or thin spots. Overall it seems rock solid and will take a lot of abuse. Looking in a bit more detail, starting from the front and working back, the flash hider is a metal copy of the Q Cherry Bomb flash hider which has threads on the outside to take a Q flash hider (Thunder Chicken or Trash Panda suppressors) however I don’t think anyone makes an airsoft version of these so if you want to fit a suppressor or another flash hider you an as the flash hider is held on with a grub screw to the -14mm threaded outer barrel. The metal outer barrel has a low-profile gas block fitted and is surrounded by a M lock style rail system. The top of the rail is full picatinny and is held on using a unique clamp system which relies on a nut to hold everything in place. The clamp system seems to be made of metal and also seems rock solid. The upper receiver is in the honey badger shape with cut-outs for the sliding stock. There are also some trades for the FALCON fire control system which is the name for the mosfet inside the gearbox. The dust cover looks to be metal and is spring loaded. The charging handle is a raptor style one and when pulled back makes the dust cover flick down however the fake bolt cover doesn’t lock to the rear so you need to hold the charging handle to the rear to adjust the Hop up. The lower receiver has a fake bolt release, metal receiver pins that are locked in place with allen headed screws, a DE trademark, an extended mag release button, plastic selectors and a very well textured and ergonomic pistol grip. The trigger is plastic but doesn’t have any flex when pulled to the rear. The trigger guard is designed for gloves and is moulded into the lower receiver (just like the real thing). The stock is in the honey badger style and inside is the battery wires which have a deans connector as standard. The Deans to Mini Tamiya in the box allow you to use a battery with a mini Tamiya connector if you want. The sliding stock has 3 positions but if you wanted to extend it more then cutting slots into the metal rails wouldn’t be an issue. The sliding stock is spring loaded so when you press the 2 side buttons to free the stock it pops out slightly making it easier to deploy. The stock cap is more like a cross between a stock pad and brace as it has a cutout on the lower part and there is a little lateral movement but nothing to panic about. There is also a sling loop at the point where the stock meets the lower receiver. The AEG comes with a set of polymer iron sights and these seem to be a copy of the IMI Defense polymer flip up sights. The sights have working elevation and windage adjustments and lack the IMI trademarks. Let’s move onto how it fires. So attaching a 7.4v Lipo in the stock tube you hear the mosfet beep to let you know it’s good. Out of the box it is set for maximum trigger pull, safe-semi-auto but after a couple of minutes following the supplied mosfet programming guide I had it on a hair trigger, with binary fire and burst set to 3 bb’s per trigger pull. Resetting it back to standard takes about 5 seconds if want to start again. With the 7.4v fitted it really is a snappy firing AEG. So snappy that when I fitted a 11.1 Lipo I didn’t see much different in semi but to be honest all this goes out the window anyway when you have the binary trigger set as when you spam the trigger in Semi there are BB’s flying all over the place. It’s awesome. Mine is firing too hot for UK sites so I’ll need to change the spring out for something a bit lower in FPS. I’ll also mention that the hop unit is a rotary designed one and looks to work well with .2g’s and I’ll try it out later with some heavier BB’s to see what it can handle. Part 2 will be a strip down and there is very little I want to change externally (unlike me) and all I will do to this one is fit a holosight and look at possibilities for fitting a tracer. Initial impressions are that it’s ridiculously good AEG for the money and I’m looking at Double Eagle in a new light. Here’s a size comparison of the 904G next to a ARP 9.

I'll have a review up in a day or 2. initial opinion is it's fantastic. DE have been terrible for years but this is their attempt to enter the better quality low budget range and so far they have knocked it out the park with this model. it's almost at the price point that if you get a few games out of it and then it breaks, chuck it away and buy another but so far the quality doesn't look like it will break anytime soon. my only gripe so far is the space for the battery isn't great 7.4v 1300Mah LIPO fits but I want to run something bigger so I've already designed a battery extension which will be free to print.

correct...they have a few different models and the longer the rail the higher the price but the internals are all the same.

Double Eagle M904G. 106 quid for a ridiculously good little AEG. Hair trigger, Binary firing and 1 to 5 round burst option on full auto. Think ARP 9 but better.

yeah it fires 40mm moscarts. inside the RPG is a long black tube that you load up and once fired need to pull the tube out to reload.

Resin 3D printed Gas plug installed until the VFC one gets here from Japan.

added the rest of the trademarks currently 3D printing a fake gas plug as I'm impatient.

naa they are Pmag grips. Not seen them on sale for a bit but they do add extra grip when removing the mag.

While waiting for the VFC gas block to tuen up I decided to have a go at doing the trade marks. I also added a end plate sling point. Trades were cut on a vinyl cutter and then spray painted. Once almost dry the vinyl is pulled off to leave the trademarks. The the whole thing is given a coat of matt varnish to stop them wearing off.

it's out of stock on octagon https://www.octagonairsoft.com/product-page/toystar-metal-body-for-k2-aeg-air-cocking but it might be worth talking to 707 arsenal as they might be able to get you one.

That looks good. The K2 always reminds me of a cross between an AR10, a M16 and a FNC. I'm tempted to build a K2 as well and I see that you can get a metal upper and lower receiver for the K".

AK5C RPG 26

I swapped the pistol grip for a VFC 416 pistol grip and I can confirm that it fits and the motor has no issues turning over the gearbox. I've swapped back to the DB pistol grip as I prefer it. I've now fitted a Gate Aster to mine and it wasn't painless but it's now fitted and working. The Aster has a hole in the centre that is used to secure to the gearbox using a screw with insulating washer. The gearbox shell has a raised post and the original trigger contacts are secured to the gearbox shell with a screw using this post. The Aster hole doesn't fit over this post. You have 2 choices, 1 is to remove the post and 2 is to enlarge the hole on the Aster. I went for option 2 and increased the hole size to 4.5mm. Drilling a bigger hole in an Aster is going to invalid the warranty so don't do this unless you are brave or stupid. The gearbox shell has some extra gears on the outside, similar to a Dboys PDW, and you need to correctly align them when rebuilding the gearbox to make sure the Ambi selectors work. When re-assembling the right hand side selector it should look like this: The left hand side should look like this: Inside the gearbox you will find steel gears, 8mm bearings, vented cylinder, plastic toothed piston and the rest is all standard V2 stuff. Everything is an OK standard so I'm not going to change anything until it breaks but being a V2 you can go crazy with upgrades if you want. I mentioned earlier that the Magazine release screwed into the button but this was wrong. It actually uses a small grub screw to hole the button to the post. It's the first time I've seen this design and it seems to be durable. So that's the review for the Double Bell BY-813S. Here's a comparison of what I started with to how it looks now. The only thing more I will do is fit an enchanced charging handle latch and fit a VFC A5 gas block when it turns up. My conclusion is that this is a good budget AEG which works fine without modification however it's easy to upgrade and being a standard V2 gearbox you will find loads of parts available to make it a very good AEG. It's a sub £200 AEG and is the same standard as a CYMA, DBOYS or any of the other budget AEG range. If you are after a HK416A5 replica then this isn't a exact match but it's cheap enough that you can buy the parts needed to make it look a lot closer without breaking the bank. This is the second Bell replica I have and both work fine so I'm now happy to go and buy another if a model appears that I want and I know that with a few upgrades it will preform very well.

yup..its the 1 or 4 mag version

I spent a bit of time earlier making the DB 416A5 look more like the real thing. I painted the stock pipe, trigger guard and fire selectors I sprayed the fake bolt cover gun metal. I removed the outer barrel extension and added a 1 inch extension and added the original flash hider. I cut down the inner barrel so that it fits inside the new outer barrel size. The Brown paint looks lighter in the photos than with the Mk1 eyeball. Next up will be fitting the Gate Aster and I'll get some photos of the gearbox internals as I go along.

feel free to post what you want on this thread. the more info the better. I cranked the gearbox open after I spent around 2 hours trying to figure out how to get it out of the receiver. The hold up was removing the selector levers. Normally you have allen bolts holding the selectors to the side of the gearbox and on this model this is the same however there are fake plates over the top of the allen bolt that have to be prised off to allow you to unscrew the allen bolt and remove both selectors. It took me ages to figure that out since there are no manuals available. The motor is an unbranded one and spins easily by hand so this rules out anything fancy. It does the job well in the stock setup and looks to be well made. The gearbox outer shell looks to be well cast and because it has a quick change spring it comes apart easily unlike the older generation of V2 gearboxes which had a tendency to thown parts far and wide when you separated the 2 halves. Inside the gearbox everything looks to be decent quality. The compression is good, there is a selector/delayer chip already installed and the piston has the first tooth removed. Shimming seems fine, grease isn't overly done and my only gripe is the anti reversal latch is loose in it's hole making it fall over when you are trying to put the gearbox halves back together. The selector plate on the left hand side is metal and I think it has 7mm bearings but I need to get my calipers and double check.
