ak2m4

I had teeth snap off my spur gear on my specna edge. I've ended up getting a new zci shell from ak2m4 with all new Gears and internals 
 

Excellent! Well found.  AK2M4 ships out very quickly and has them in stock as well (https://www.ak2m4.co.uk/internal-parts/misc-internal-parts). 

Sorry not a clue what they put in Rapax from stock.  Best way is to give the current readings together with a pic of the stock spring and if possible thickness measurement of the wire.  Otherwise grab an XT M100 and test and adjust.

Purchased as a project for £50. I've 3D printed some wood furniture for it and I'm mostly happy with how it turned out. Printed in walnut 30% wood PLA, 1 coat of walnut wood dye and 1 coat of teak wood varnish. 
 
Internal upgrades:
 
- Perun V2
- Maple Leaf 70 degree rubber
- Tomtac 6.02 barrel. (Brilliant barrels for the cost. Apparently they might be rebranded ZCI?)
- ZCI closed cylinder
- XT cylidner and piston head 
- M130 spring
 
FPS is a solid 430fps with semi locked via the Perun. The plastic receiver sucks but I'm on the hunt for a G&G magnesium reciever to replace it with.

Can't beat Airsoft and Sex Toys 🙂
 

ordered from them about 2 months ago, was listed as in stock, waited 3 weeks, emailed them two or three time, they replied we're waiting for it to come back in stock. Waited another 3 weeks, still nothing.  Politely asked for a refund.  Was ignored for another 2 weeks before I asked Paypal to step in, then got refunded.

 

To give you an idea Maple Leaf lips are 1.9mm long, whereas most are around 1.2mm (I think, need to check, got all measurements round here somewhere).
 
Also the aperture of the Maple Leaf is wide enough to park a bus, ok so wide enough to let a BB fall through without any encouragement, whereas standard buckings a BB will sit on top of the whole waiting for a little tap to proceed.

Ditch the Maple Leaf for now and try just a regular bucking for now.

Sounds to me like either the o-ring on the piston head is too small for the cylinder or the vents are clogged up stopping the oring from being pushed out.

Will do that... Might have to be done in stages.  Have a mad week with work, plus SWMBO is flying back at silly O'clock Thursday morning so have to hide our arsenal that she doesn't know has built up over the last year 😎
One thing springs to mind, is that the gearbox locked up and I freed it by releasing the anti reversal latch through the motor housing...  Pretty sure the problem had already occurred by that point though, and the gun does cycle and operate OK visually with a decent puff of air coming out of the nozzle when the barrel is taken off.

A small nick in the oring generally wouldn't cause it to not fire, maybe a small drop in power.  You're going to have to open it up, could be something super simple.  Open it up, post up some pictures or even better a video.

I've just fitted this kit into my specna arms E07.

Excellent consistently.

Bank of Scotchland were doing internet banking on it before there was an internet.  I shudder to think what security it didn't  have back then.  5p a minute (that could buy a Caramac bar!) daytime rates, on top of BT call charges, I'm surprised it ever got to 90,000 subscribers.

Site looks pretty legit, I think I'd be more worried about thread compatibility.  When I used to sell these mlok and nsr rails I had nothing but issues with them.  In the end I was lucky to stumble across a manufacturer who did a barrel nut with 2 different threads. 

from what I understand he used to have a good rep..... and then things started slipping. I think it was dave oakfield/renniks (of maple leaf tactical for those old enough to remember!) did a big post about him about a year ago and how he hadn't done the honourable thing with quite an expensive PTW A2 (memory is fuzzy, could have sworn it's Jtac) leaving him quite out of pocket etc. I don't know if that got resolved.
 
Unfortunately this is the sort of thing you hear every now and then, someone is good, they get a good rep and to keep orders flowing in their prices stay the same, they get flooded with orders and can't cope. They either increase their headcount etc (which is a massive gamble as employees generally aren't as good), they up their prices etc. or stuff slips. 
 
Some unfortunately just try to soldier on, work all the hours, barely make any money, good service turns to bad and suddenly they're in super deep and stories like this start coming out. I reckon most of them aren't doing it with the intention of being bad, just that real life happens and they get overwhelmed or lose the passion for it and have an honest intention of "I'll get that sorted next weekend"......next weekend become the one after etc. 
 
I don't know the specifics for Jtac or the situation there, but it's a name and a company I personally avoid based on what I have heard. 

Ok so I figure in fairness I will name the tech and give the story so there's some context.
Back in March last year I contacted John Boycie Turrell formerly Jtac custom. I had dealt with him for parts and never had any problems or issues. I also knew he did a lot of work on kwa rifs before and wanted someone who knew their away around them. All was fine and the rif was posted away and received. He did mention it might be a few weeks as he was going away for a couple of weeks on holiday. No biggie I was happy to wait a couple of weeks.
 
So towards the end of May I chase it up and he hasn't had a chance to look at it due to a new job and 60 hour working week.. I figure life hits and leave it there
 
Late August comes round, I haven't played in months as I'm down to 1 rif and it's time to chase it up again as no communication. At this point I'm informed he hasn't been able to look at it and has passed it onto another tech named Adam and he should have been in contact. So he will chase it up. I should point out that at no point have I been asked if that's OK or even asked if I wanted it sent to another tech.
 
Work jumps in for a bit and come mid October I send John the 1st sort of message indicating I'm not happy and would like my rif back. So far this other tech who I only know as Adam has made no contact with me. Once again promises he will chase it up.
 
It then transpires Adam hasn't touched it, I'm invited into another conversation with another tech Jimmy who offers to sort the rif out for the cost of parts only if any are needed. In an a bid to get the rif sorted and home I agree.
 
So December 9th comes around and I have heard nothing so I message Jimmy to see if he has seen the rif. Guess what. He hasn't received it. I know Jimmy's last name, but I'm not mentioning it as he is a blameless part of this saga.
I chase John again, tell him I just want the rif back now whether it's in 100 pieces or 1 and I will sort it myself.
I'm told he will get it back from Adam and get it sent back to me. Along with comments about how he hates letting people down and life gets in the way.
I'm still trying to be nice at this point as I want the rif back and like a fool I trust people further than I should.
 
December 30th cones around. A slightly sarcastic 'I guess there's no sign of my rif being returned then' message goes off.
I'm told there is and it will be posted UPS on Tuesday(January 3rd) due to the postal strikes etc. So a little spark of hope flares.
Tuesday comes and goes I wait until the Friday and chase it up. Message gets ignore.
 
At this point I start to genuinely believe that the rif has gone, or sold or something. I had a few friends including my Mrs tell me i wouldn't see it again.
A combination of bad work life, some pretty crappy normal life stuff combined with not playing airsoft due to only having 1 unreliable rif. Has all combined to have me pretty low and heading towards a depression spiral at this point.
 
So Monday comes (January 9th). Probably due to me being a Moody git all day the Mrs says send him a more forceful message or resign yourself to never seeing it again.
So I do, effectively asking why I haven't had the rif back, wanting answers and closure due to it affecting my mental health. A couple of hours later im asked for my address, email and phone number. I'm then sent a photo of a box with a UPS label on it that looks suspiciously like the one I originally posted. 
Sire enough 2 days later it arrives home (hoooray) and its the same package I sent away, it hasn't been opened, not even the plastic wrap on the outside.
 
I have tried to give a full, lengthy view of what happened as I don't know if this 'adam' tech exists and if so whether the full blame lies with him or with John.

Wow, that's a shit story, please please name the so called tech that's monumentally fucked you about so that nobody else gets suckered by him, maybe you should be thankful that he actually didn't open it, he sounds like a 'tard. 
As for the rif itself, sounds like you packaged it very very well, good job too, if you've opened it up found no exterior moisture or any signs of oxidation on the alloy parts, then I wouldn't worry too much, it should be fine to use, or at least be in the same condition you sent it off in. 
Hope that helps

All good explanations.  This time last year the £ was trading around 1.35 vs the $, today it's 1.2.  When you have to purchase a 20 foot container that small increase is gonna hurt.  

We'll know it's bad if the DFS sale ends! 😂

Times are hard for everyone, including airsoft retailers; their operating costs have gone through the roof while sales have decreased, partly through unavailability of stock due to lockdowns in China and the lingering impact of logistics issues.  Already tight margins have been squeezed to the point where offering discounts is not viable.
 
 
 
 

Be interesting to see what you get, I've done several nozzle tests recently, with o-rings against those without, good seal nozzle at retracted and extended point vs one with no seal and the fps was always the same.  A lot of other variables of course and no 2 setups are ever the same.  Let us know how you get on.

Only 1kg, would only be £3.95 via Royal Mail 24 Tracked service.  
 
My guess is in order to simplify their website backend shipping function they just use a single shipping weight.  It's a pretty lazy way doing shipping but very tempting as it can cut a huge amount of confusion.  Took me a few hours to get my head around how the shipping worked and I had to "fudge" the system in order to get it working as I wanted.  So many work-arounds.

Airsoft companies have been over charging for years sadly.  Some do it to try to get the customer to order more items in the attempt to justify the shipping etc.  I actually subsidise 90% of the shipping fees in order to retain customers.  £12.99 is very high for some BB's, what was the total weight?

It is not a question of could it be fixed, its a question of should it be.  Spend some money and get a decent 7.4 Lipo and a good balance charger

Can't beat Airsoft and Sex Toys 🙂
 

Been testing this for the past 4 weeks and so far hasn't broken.  It's a fully mechanical ETU with 4 micro-arms.  I've always been a little sceptical of these type of FET's due to the unreliability of the switches but this one is proving pretty decent so far.   I'm organising a small test of these with 10 or 20 regular players later this week, hopefully will see if they last the distance and how serviceable these are.  Price should be around £35
 
Will update the thread with the findings.
