@RostokMcSpoons found one, it's OD is 2.4mm, I'll message you direct

let me have a quick look this afternoon and I'll send you some over, I'm sure I'm got loads which will fit 🙂

@RostokMcSpoons I don't really, I have some longer ones which seem the right OD but from experience I've noticed brands use all sorts of different sizes. Maybe someone can measure one?

@Rogerborg I noticed a site the other day doing calendar months as well. Always wondered if maybe a site would "credit" a visit that you made to another site, if you asked nicely and showed proof. Never heard of this happening before though and wouldn't be in the interests of the site.

Multi-site UKARA sadly isn't recorded. @Tommikka The system I was working on last year had a workable solution for multi-sites that was even partly developed however my developer seemingly disappeared into the ether'net 😞 Just haven't had the time to pick up on it.

It's 9" sadly. It's an NSR, has a steel barrel nut. Tried it on my aeg uppers that I have lying around and nothing fitted. You're welcome to try it out to see if it fits yours. I'll message you.

the barrel nut is most likely aluminium which are subject to getting munched up. I do think it's milspec indeed: https://www.reddit.com/r/airsoft/comments/4jdldi/tipmann_barrel_nut_thread_size/ I'll dig out and test the NSR one I have.

If Tippman does use GBB threads I might have a 7" NSR rail kicking around, I'll see if i can dig it out

A chap I know runs this store: https://www.aliexpress.com/store/912499189 I imagine nuts are AEG spec, Tippman use real-steal / gbb thread right?

LVOA kits are an acquired taste, even moreso at 16", I still have a new 13.5" for sale somewhere that I could never shift. Will probably let it go for £50, sick of looking at it 🙂 Maybe you should split the items?

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.

From what I've been told the fet the ss4 uses is the same / very similar to the ChiLuns, it could be that the one of the micro-switches is failing. Had it happen to one of the test ones. Maybe email and Nov support and they might put you in touch with the guy who does the UK support.

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.

yes, even something 0.5mm can cause issues. what's the length of the stock and new nozzle? have you tried fitting the old nozzle?

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.

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.

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.

I don't think it will work since barrel nuts are all different

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.

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.

Ahhh you're in Sweden, sorry assumed you were in the UK. Forget what I said about the fps issues.

What brand was the M120? Was it stock? What FPS / Joules were you getting with the M120? Were you running it as a DMR? as a M120 should push you way over the legal limit As @Terry_Rist said most likely the motor is spinning the gears too fast for the sp90 spring to cope. Moving to a 7.4v battery should fix the issue but seems like you've perhaps got some fps issues. Anyone remember if Arcturus short-stroke their gears on these cheaper end models?

I think the problem is GBB makes up such a small % of sales so most are reluctant to stock parts which is a shame. Back in the day when I was into GBB everything had to come from Hong Kong but at least you could get it all from 1 store 🙂

@Rogerborg Thanks, and yes making a loss. However my postage fees are due to rise in the new year when I switch to more of a fully tracked system. I might still keep the cheaper large letter sub £20 sub 100g rates, not made up my mind yet.

They have a fairly active FB page, seems pretty decent. The mine part of the site looks a little sparse, I'm guessing they aren't allowed to build any structures inside?
