A more interesting proposition might be using the thermo plastic that gum shields use so a user can trim and shape to their own face? Maybe make it with in-moulded mesh for the mouth. TBH the cheap mesh masks are pretty easy to re-shape and tweak to the users (unless they have the face of Gonzo!) and stuff like DeltaFacePro is so light and comfy I am not sure there is a gap in the market.

I have the Cyma Krinkov AKS-74U and a stick 11.1v LiPo (AK speck, 19mm dia?) will fit all the way through the wooden hand guard, I also owned the "Tactical" version and again the battery would slide into the front grip / gas tube area. Obvs the CM040 is a different beast but it might work. It currently runs a 7.4v lipo (120mm x 14mm x 18mm) that slides in easily (Ooh Matron!) and leaves plenty of room for the Gate NanoHard Mosfet. With a M115 spring, 16:1 gears, short stroked 3 teeth and a SHS High Torque motor it is a little monster Full auto isn't crazy fast but the semi auto trigger response is great (even with the horrible v3 trigger)

2nd hand Cyma CM041 highspeed stripped of the dark green / black camo paint. Re-shimmed gears, already short stroked 4 teeth on the sector gear so took 4 off the rack to prevent PEM. Wired in a Gate MERF mosfet to the rear (loads of room in the stock) new air nozzle (worst part of any Cyma!) and threw in a Maple Leaf hop rubber and nub. G&P front end with LED torch, I have some 2mm lexan coming to make a lens protector for the inevitable CQB shoot out 🤣 Shooting 340fps (+/- 2fps) on 0.20g and 19rps on a 7.4v I could run an 11.1v but I don't need 27rps!

I have booked Spartan woodland on the 18th as not fast enough to get anything else! Can't wait for StrikeForceCQB and UCAP VENDETTA to re-open later in the spring for some close up fun.

A lot like this! 1😁

Best way of filling any gas mag is in 1s bursts. Fill for 1sec, stop, wait a couple of seconds then give it another 1sec burst of gas. Keep doing this until full. Should be able to top off the mag that way! Give that a go and see how many shots you get from 12x 1sec fills

Do you mean run both motor wires out the "back" of the pistol grip thus avoiding the red wire crossing the pinion shaft (hehe he said shaft)? Might be enough room then for the 4 wires at the back of the gearbox and just the hot-glued out the way signal wires going to the front part.

I am planning to fit a Gate MERF mosfet to my Cyma MP-5 High Speed. The gun will be rear wired with the battery and mosfet in the fixed stock. Being a v2 gear box there isn't room for two 16AWG Silicone wires (motor) and 2 thin signal wired in the gearbox shell, especially around the motor entry point. I usually use these larger diameter wires to keep the resistance down, although this came stock with 18 AWG and an extender section to make it front wired...so I guess it was suitable? My plan is to use 18 AWG wire from a Deans connector at the back of the gear box to run the power wires to the motor and have room for the trigger contact signal wires. The MOSFET will sit in the stock up near the back of the receiver (I can always pop the stock off if i need to change settings / get at it) This will keep the thinner wires to a minimum. There will be a Deans connector and enough 16 AWG silicone wire from the other end of the MOSFET to the battery connector which I can grab from the open end of the stock pad. I am guessing the larger diameter wire will be better (less resistance) and there is loads of room in the stock so it seems silly not to? I had forgotten how much I hate v2s!

Sooo that was a cursed build! Gate MOSFET seems to be happy now, but the +ve "wire" on my 11.1v Li-Ion gave up because it was made from a thin piece of tin foil...and we all know what happens to that it you bend it 3 times FPS were still all over the place and misfeeding every other shot. Then, for no reason, the piston jammed and the piston head gouged a chunk out of the cylinder....WHISKY TANGO FOXTROT?!!! Luckily I popped an order into AK2M4 and had a new cylinder, piston head and 2x Cyma pistons waiting for me when I got home. I rebuilt it all stock (including the dodgy blue air nozzle) and it ran fine at 330fps, consistent (+/-4fps) and no misfeeds using the old 7.4v LiPo from my M4. I put in the SHS high torque motor and tested again. Quicker response and still feeding / good FPS. I then swapped out the gears for SHS 16:1 short stroked 2 teeth, the other Cyma piston (again -2 teeth) and the o-ring nozzle. M115 spring gave me 345fps on average hopped for 0.28g Super snappy in semi-auto, full auto is ok but I rarely use that. I think the feeding issue was due to the Strong Tappet Spring wasn't as strong as the stock one and 13:1 on 11.1v might have been taking the piss a bit 🤪 Safe to say I never want to take it apart again for at least 3 years (but if I do I will be damn quick at it!)

Please don't watch it but "SAS: Red Notice" had the blades kitted out in reject kit from the local airsoft site rentals bin 🤪 Shockingly bad film with some well known actors in it (who probably got new agents after that 💩show!)

Yep, one of the first things I checked. Just had the shed wired for power and light so good excuse to test it

So, an update: The "error flashes" were actually "11.1v battery" - totally user error. There were no lights in error mode, but I pressed and held the button to reset it anyway. This seemed to let it cycle a couple of times then nothing. I checked the gear box for jammed tappets / pistons off the rails / random shims - nothing jammed and all moving really smoothly. I rebuilt the gearbox without the cylinder / piston / spring or tappet just to check it span the gears on their own with zero resistance - exactly the same, couple of cycles then only a green LED when you pull the trigger. I am going to fire off an email to Gate EU as this MOSFET is under a year old and not even skirmished yet. Thanks for all the suggestions and lack of "obviously beyond help, sent it to me for a tenner" comments

Just changed it back to 16:1 gears, std motor and M100 spring....still doing the same. Even with the motor cage off the GB when I pull the trigger the motor might click once but that is it...wondering if the MOSFET is borked?!

Ok, I am a bit flummoxed. Having time on my hands I thought I would put some high speed gears and high torque motor into my AKS-74U and short stroke the piston to make it a snappy CQB gun. Before I started tinkering all I had done to it was shim, replace the nasty blue air nozzle and hard wire in a Gate NanoHard MOSFET. It was putting out about 335fps +/-2fps and 18rps with an 11.1v stick battery. Today the package from the great Peter at AK2M4 arrived so after lunch I stripped down the AK and started to fit the parts. The rack and sector gear were short stroked by 4 teeth (it has a very short barrel so no need for the volume) a Rocket M115 spring and the SHS High Torque motor fitted. Now for the weird stuff, initially it was putting out about 280fps....but after 10 shots this started to drop and ended up around 110fps! I opened the gearbox again and added 8mm spacer to the back of the spring as a stop gap measure to see how it effected the fps. Now it will only occasionally fire, the MOSFET is bitching about "too much current" When I pull the trigger the green led on the MOSFET comes on and then fades out again, no movement from the motor. I guess it is sensing the trigger contacts but then cutting the power once the Amps get above a certain level (and before the motor turns over at all!) Any ideas before I fit a new piston rack and re-fit all the old parts?!

Worth mentioning that if you want no fogging, face and ear protection and certified lens's the Dye i4 is worth every penny. My first airsoft purchase (as playing loads of CQB) and you can get them in camo / subdued colours if you are not a speedyboi 🤣 Only possible downside is needing to raise your optic a bit higher, depending on platform (MP5 amd AK are not an issue)

Yes, those are the ones.

yeah, not been doing much lately. With the dark nights and weather I have not been cycling to the office (on days I am in!) and runs are loooow on the list. Now my lower back issue has resolved its self (for now) I need to get back into some running in the evenings and some bodyweight / dumbbell exercise other times. Literally my Trevail 5kg plates every time I go into the shed:

I have been running Bolle Tracker II's for the last few years with FogStop (FaceBook) or ReVision antifog wipes. DeltaMike face pro is great and can be used with ear protection. I have Honeywell set, active protection / amplification and comms input....plus half the price and ACTUALLY WORK vs Earmor! EdgarBrothers stock them. Ear pro is a good idea because being shot in the ear really, really hurts and tinnitus is a bitch. Outdoors might not be an issue but a Mk5 going off in the 2m x 1m concrete cell you are in is another matter!

The outer barrel set you linked to seems to include the adaptor ring?! Might be worth emailing / calling Firesupport to check...they are really helpful.

Glad I could pass on some useful info

Adding the "silent fill" o-rings will limit the amount of gas you can get in the mag as it can't vent the air already in there. Top tip I learnt only the other day is to fill a mag in bursts. If you want a 6sec fill do it in 1sec bursts and wait a few seconds between fills. Oh, and Badabing is UK based so no 30deg Arizona heat helping the gas pressure 😁

Probably 1.5mm thick? Sturdy but doesn't weigh a tonne. Finish is painted rather than blued like E&L's....but hey, they are 2x the price. My Krinkov has a nasty beat up and rusty finish thanks to some sandpaper and water / orange acrylic wash so probably not a good example 🤣

I have had two CM045s and can confirm that the receivers are stamped sheet steel.

For the money current Cyma are really good value. I have had a couple of the CM045 (AKS-74U Krinkov) and NegativeAirsoft is impressed by the current Platinum M4 range. I have seen good, in depth, reviews of the Blue and HighSpeed versions of the MP5. Prices are between £150-250 so would leave you money for some extra mags, chest rig and batteries.

I have just done some work on my AEG and I had forgotten how horrible stripping and working on a M4 with v2 gearbox was! Now short stroked 3 teeth, new motor and M110 spring. Not going to open it again until it fails!
