Low fps could it be cylinder related?

Epic thanks for this. Next job on the list 😄 -

That was before being cleaned and lubed up. Was wetter than Gemma Collins mouth in greggs What’s the correct O ring size for the piston and cylinder head ? -

It’s a weird one as I grabbed the old gear box that came out of it and serviced it fully. When I opened it up the tappet plate looked different. It has a moon shape on the tail end and there is a delay chip however the nozzle is shorter than what I had in the eon gb. When I fitted it all back together (with a clean inner barrel and bucking) I got 335 fps and 1.28j (no hop applied) 🤦♂️🤷🏻♂️ I guess this is an easier problem to fix the the latter lol images are of the gb that came with the gun when I brought it 2nd hand -

So the paper moved a fair bit so I’m guessing air is escaping 🤦♂️ IMG_3676.mov -

Yeah fair point. Not done anything to it since I brought it off a seller. I think it was thrown together with bits from the Airsoft fair -

Awesome thanks I’ll try this. if there is a leak does that mean I should fit a delay chip or slightly longer nozzle? -

When you say timing do you mean when the nozzle moves forward and locates the bb into the feed lips before the piston sends the air down? Sorry if that’s a stupid question also where should the nozzle locate to when it enters the hop again? I am not getting any miss feeding when the gun fires bbs fly so I think the retraction etc is ok -

Probably length as it’s the same I used previously with a health fps. Maybe too short? What other lengths are there for an m4 v2gb? -

Tbf I don’t think it’s over 400mm however I’ll check once I’m back home. Based on my poorly calibrated eyes I’m guessing between 350 to 370 in the past I’ve had similar platforms with nozzle related issues but I fitted an O ring to make sure the hop was as tight as poss to the gb/nozzle and the fps dropped 5 points 🤷🏻♂️ -

So it’s a V2 gear box, Maple leaf 60 degree bucking, no delay chip, 13:1 gears, 18000 ASG motor, Rocket v2 tappet plate, SHS nozzle 21.4mm, Gate EON protector cylinder head, EON Power hybrid cylinder head. Hop unit looks like a basic rotary unit but it was what come with the shell/receiver when I brought it second hand. The hop unit I used to run when fitted to the inner barrel, wouldn’t let the upper receiver fit all the way into the lower Reciever (this one has happened to me twice now so I’m wondering if some how I’ve made a school boy error when putting the upper back together) I’ll get the measurements on the inner barrel and some more pictures later -

This is the cylinder. I managed to find the invoice from when I brought it. I’m taking the gun apart this avo so I’ll measure the inner barrel -

useless picture I know but the only one I have currently. I think it’s about half way down to two thirds of the way -
I’ve found a home for a gear box I had to take out of a polycarb body that broke. It’s got a M105 spring, eon piston head, cylinder head etc. The inner barrel on the previous gun was was under 300mm and I’d get a good 300fps on 0.25g. This guns inner barrel is over 300mm and I’m getting 215fps on 0.25g 😱 Ive checked the compression on the cylinder and nozzle and piston and it’s spot on. is it possible the cylinder port needs to be further back so I need to buy another one? or could it be something else ?

Cheers. I thought that might of been the case 👍

I’ve just swapped a v2 gear box from a king arms m4 into a lancer tactical m4. Both v2 gbs. all went ok until I went to fit the upper reciever back and it wouldn’t locate all the way back by 3-5mm. i swapped the hops over no change. When I remove the hop and inner barrel it locates perfect. What am I missing apart from hope?

Fair point. I’m gonna try make is at close to a m249 as poss. I’m cheap skating the golden eagle 6669 tbf lol

Evening - has anyone ever moved an m4 over to an lmg. If so what did you do to modify it? sounds random but I’ve got an itch for an lmg build but have m4s to play with

Chaps and chapesses Ive got the HPA engine working on my mates gun but I think he will need a better mag. It’s mid cap DE stock one. I don’t think PTS do one. Anyone know of a good place to try or is it possible to upgrade a mid cap spring?
