Afternoon So I’ve had a gun come my way (fk why) which has been converted to HPA. It’s using a Titan Bluetooth2 trig unit and a Pulsar-S open bolt HPA engine. When you fire it the bb dribbles out the barrel (after you tilt it forward). When I put my finger on the barrel as I pull the trigger the airflow felt weak. Turned up the flow on reg not much changed. I changed the timings on the main valve(db) from 5ms up in increments of 5ms to 25ms and nothing changed. It’s not the Pulsar S with a purple nozzle it has the silver/beige noz. I read that it could be a problem with the feed lips. I did a quick check to see what the resistance was like by dropping a bb in and pushing it through. Tbh there wasn’t much there. I did the same with a spare hop I had which had a maple leaf bucking and there was a difference. I’ve swapped the hop and bucking over. I now have excellent air flow coming out per shot but now no bb is coming through the hop. I was wondering if the maple leaf lips were a fraction to long as I’ve had this before on an aeg I tweaked. anyone ever done any similar works that could guide me ?

Yeah that’s got the issue more under control. I need to get the power down now to 1.44j as I’m a bit hot at 1.62

Yeah I’ve got options. Once that’s done I need to get the power down a tad and I’m then sorted

Yeah true. Found a 690mm on the links above so that will do

Cyma Dragunov SVD. It’s got a 695 inner barrel 🤦‍♂️

I did use a 11.1v son gonna try a 7.4v tonight No optical controller pretty basic insides tbh Ok I’ll try the battery and when I’ve exhausted everything I know that is an option. I’ve tried the take it out try again several times however it did it before I took it appart

Awesome thanks for this !!

Afternoon - I am looking for a inner barrel with a length between 650mm to 695mm and a bore of 6.05mm minimum. Any suggestions on where to try as I’ve googled the nuts out of it and can’t find what I want 😊

Evening all so My CYMA CM.057B (Dragunov SVD variant AEG) randomly is firing out two bbs with one trigger pull. It was doing it after game day one with zero modifications done. I’ve checked the bucking and this is in next to new condition. I have added a M120 spring and on .25g it’s achieving 1.6j. I’m using cyma svd mid cap mags as the hi cap that came with it broke on day one and I thought originally that may have been the issue. I’ve seen about drilling a 6mm grove into the top of the hop to help hold a bb in place but is this a legit solution ?

Awesome thanks for this!!

Hi - I’ve got a cyma .702c I’m looking at for a mate and he needs a new bucking rubber. I’ve not seen one like what’s on there but I’ve only ever worked on aegs. Anyone can guide me on the right one please

7.4v buddy Mid cap mags 0.25g as I’m waiting for 0.4g to be delivered 7.4v i have a high cap what come with it and two cyma mid caps that I brought. All do the same bucking us in good order however it is the one that came with the gun no other mods done just a new spring and the prob was there with the old one also Lmfao 🤣 it goes pew but two bbs come out one like the first splodge on the wife’s jubblies the second like the third haha

Morning folks - I’ve got an SVD variant from cyma. Every few shots it throws out two or three rounds together. Looking at the cylinder it has no ports and I’m wondering if it’s causing a vacuum. Anyone else had similar issues?

I guess not the worst suggestion

Evening folks ive gone a splashed some dollar on a classic Army micro mini gun. Yep it’s a nice toy but then it dawned on me………………….. how on earth do I chrono the dam thing does anyone know how?

Got it all sorted and it’s a beast now 😊

It’s a nuprol defender. It’s got a six inch poly hand gaurd that splits into a top and bottom halves. The top half has forks which locator in a grove where the barrel nut (I think that’s what it’s called) site. The forks tho are crap and the tangs snapped hence the need now to replace.

Not sensor related, piston head came off 🤔🤦‍♂️

So in the end I went back to the original gear box and the issue persisted. however it looked like the nozzle was coming back to soon so I removed the delay chip and boom back up to fps as before. There are the odd inconsistencies but it played well on Sunday until the end of the last game when the Titan brought up a fault I’m yet to investigate but guessing it will be sensor related

So I am looking to replace my plastic hand gaurd with a metal one but I’m not sure if it’s as easy as a like for like swap will I need any parts other than the guard?

Cheers. I opted for the delete as the pictures related to solved issues mostly so I’m now back fully charged haha 😛
