Unfortunately mine didnt come with a manual so i have no idea if the sleep mode is an actual thing or if its just a quirk of leaving the mag in the gun for a while. 
also sample of 1. probably a good idea to wait for a variety of reviews XD

not tested that yet but ive fired 3-4 mags through on one charge so far with no signs of slowing down. When I initially stuck it on the charger I only left it for 10 minutes and I got one or two jams where it couldnt quite cock itself but after an hour of charging I havent had a single jam from this charge
Once there are spare mags available unless you are using it as a primary in cqb I dont think battery capacity will be an issue 

yeah just tested. About 4 mags is where it starts having issues. so around 64 clean shots and then it every now and again slows down slightly. Still runs but it just sometimes has to take a moment to recock itself. So treating this as if it were the gas capacity of a magazine it is still perfectly fine for a sidarm with the one downside of being more difficult to top up if you are out on a milsim or something. 

On another note the gun seems to have some sort of sleep mode. If I leave it with a mag in for a long while it will take half a second after shooting to actually start recocking itself. I only get this occasionally so im not sure what to make of it yet

MOV_4203.mp4 Yes I know that I had the safety turned off when I did that little demo. I am the dum but yes I can confirm the left side safety does nothing to stop the gun from firing

So ive seen these around with very limited information. Seems to be about 200fps, holds 17 bbs and has the battery in the magazine. It works on a system similar to the gbls das or some of the older guns that preceded that and some newer nerf guns. That meaning you get a mechanical trigger that releases the sear on the piston and then the motor automatically kicks in to recock that piston and make the slide cycle.
 
Probably a bad idea to be an early adopter but ive always liked aeps and this just seems so cool ive ordered one. Ill post more once I have it. No spare mags available anywhere at the mo but its only been out for 4-5 months or so and less than that in the uk.
 

oh. Ive gotten it apart. there are 3 pins in the frame holding the chassis in but you can actually take the slide off like any normal pistol. just punching out the slide release though you do have to make sure it is not cocked first. Internals look very robust, ill post pics later. notably the catch surface, the teeth on the slide and some of the other wear parts seem to be seperately replacable with screwed in inserts. 

Edit: also i was wrong. Left hand safety is entirely aesthetic, right hand is the working one

So I just got mine. Fairly stiff prime by hand but it is surprisingly snappy. Trigger is quite nice if fairly light. Safety feels a little cheap and despite being on both sides the safeties are not connected. Both of them disconnect the trigger but you are gonna have to pick one and leave the other off. I dont tend to use manual safeties anyway so this isnt really an issue for me. Not the first clue on how to disassemble and there is no manual in the box. had one or two jams due to not charging the battery fully meaning the gears didnt quite make it all the way around but racking the slide spun the gears and put it back into manual and with a proper charge ive yet to have any issues. Range its pretty good for a sidearm, around 200fps on a .25. It feels a little on the chunky side but Its been a while since I had the raptor so it may just be how the actual grach feels. It isnt noticeably fat like the old 1911 aeps. it looks as it should. 

EBB pistols have come on a bit by the looks of things. Does look and sound rather snappy.
 
 

Patrol base already have them in stock. thats where I bought mine. https://www.patrolbase.co.uk/cyma-cm-136-grach-ebb-mosfet-edition

Same issue, just I didn’t send mine back and still have it 😂

I would assume(possibly incorrectly) that most m4 uppers will fit.
 
HuttArmories usually has plenty of kit for sale & at decent prices.

bottom half of the belt feed mech is getting there though I still need to build in a way to attach the box mag / mag adapter. Still tweaking the hpa adapter but it now only seems to leak from the bolt holes, the top half is entirely sealed so it may just be a matter of getting a metal one so I can better seal the threads. Decided for the vn mags ill be mounting it so they come in at an angle just below the feed ramp on the side so that the hanging belt can hide the end of it. should also mean I can get lower to the ground. I had a beaten up old tm g3 bipod and the hk21e bipod seems to use the same latch mechanism so i just chopped it a little shorter and made a new block for the top of it so it can slide into the handguard caps. 

So in all my various dealings and buying and selling ive ended up with about 30 magazines for the kj works m93r rebranded by si. Minor problem is that noone seems to have one. Ive never seen one in the wild and no one wants to buy the mags. Secondly ive always wanted some sort of little sub machinegun as both a sidearm to my lmgs and as a nice light gun for more compact fields. and so I decided to build one. Ive made a new nozzle to work with these mags but it uses glock rocket valves and piston heads. It blows back already but obviously I cant test feeding or fps yet. Either way I didnt really expect to get it this far but it just worked first time I tested it XD. Im probably gonna go for something like a vz23 with a simple metal tube upper. Eventually a beretta mx4 storm may be on the cards since these are beretta mags. We will see how it goes.

So im working on a hk21 machinegun project. The base gun is a we g3 and i plan to hpa tap the original mag and hide it and the fitting inside the box mag. Anyone run a lot of gas blowback full auto around? Any advice would be appreciated as apart from testing guns I got to re sell this is my first experience with hpa.

Yeah Ive seen that one though since im basically modifying a rifle its closer to their colt lmg or hbar builds

Was watching this last night & the last 10mins or so made me think it might give you some other options...
 
 

You posted this just before I was about to put an update on XD.  So originally I was trying to use the original mag and hide it inside the box mag which would have lead to a much larger box mag than reel steel. I was also considering chopping the mag in half and splicing it smaller until @The_Lord_Poncho Made a suggestion that had somehow entirely slipped my mind "3d print one" And so I have designed and printed a new bottom part using the top half of the original we magazine, no modification needed. To be clear this will be sent off to be machined or printed in metal before I use it but I have tested it by pumping it up very slightly with my hpa pump (while wearing safety glasses) and it does infact cycle the gun just fine though it leaks around the bolts even with o rings which a metal version will hopefully fix. Did also have to remove the paddle mag release to get the connector in a good spot. 
 


having it this short also opens up an interesting possibility. I think I am going to add onto the bottom of it a dovetail or something similar and while I will make a box mag to use I am also considering a magazine adapter for vietnam style short m4 mags. With the belt feed mechanism and a short length of dummy 7.62 the mag would be barely noticeable and id be able to run the gun without the need for a box mag. Obviously Id need to get myself a supply of vn midcaps which are hard as hell to come across right now but I think this could be a great way to use it. If anyone has any suggestion's for some other 100 or so round midcaps that would be small enough to not be noticeable Id appreciate any ideas.  

Also 3d printed a guide to mark out the holes on the handguard and started drilling and cutting them into some 40mm aluminum pipe. The raised ridges on the handguard will be 3d printed additions and all of the small holes are threaded for m5 bolts so I can swap the ridges out for rail sections and the offset foregrip when I get around to modeling and printing it. 
 

 

Looking phenomenal!
