Supporters Airsoft-Ed Posted September 21, 2013 Supporters Share Posted September 21, 2013 I dunno if many, or any of you will be able to help on this, but I thought I might as well start the quest for more information somewhere.As some may know, I have a custom SR25 - Mine is modelled off the A&K URX version and as the more gun savvy of you will know, some SR25s use a long gearbox and standard hop, whilst others use a longer hop and standard gearbox. They have to use one of the two to get over the added length you get from using a 7.62mm receiver instead of a standard M4/16 type 5.56mm one. So I have a few questions: Forgetting the P* FE for a moment, would it be possible to fit a regular V2 and long hop/air nozzle to my SR25, bearing in mind it's built for a long g'box and regular hop?In short, are the major internal components (hop and gearbox) from the two types of SR25 interchangeable? Second question, is there a long style P* Fusion Engine on the market? Or is there ever likely to be one? I'm pretty set on saving up and getting a Fusion Engine in my SR25 somehow, so I'm trying to figure out if getting a standard Version 2 style FE, a longer air nozzle and a longer hop, would work, or if it's going to have to use a specialised FE. I've emailed The Grange about it this morning as well as asking via Facebook, so I'll see what comes from that, but I'll also probably stick something on Reddit, since most of them are yanks and will have wider access to P* stuff. Anyone know anything? Link to comment Share on other sites More sharing options...
geoffreym Posted September 21, 2013 Share Posted September 21, 2013 Check out a person called bingo airsoft, he's your best bet. p.s. I was thinking about putting a P* into a Socom Gear Barrett to make an awesome sniper rifle, the principle is great , making it work might be a bastard though.

Supporters Airsoft-Ed Posted September 21, 2013 Author Supporters Share Posted September 21, 2013 Just done some digging. People seem to suggest that G&G hop units and nozzles will fit the A&K, and P* actually make a specialist nozzle to fit the G&G SR25, which means I ought to be able to get a regular V2 Fusion Engine, G&G hop, P* G&G SR25 nozzle, air tank, regulator, control unit and then it's just a case of experimenting with various hop combinations and getting a murderously expensive, epic tightbore. Fusion Engines are £450, the control unit is £20, the air tank is £50, the nozzle and hop are both £30 each, the barrel will set me back around £100, experimenting with hops and nubs will be about £50 or so... I'ma set a budget of £750, and I'm going to aim to have it done by around 2015 lol. Link to comment Share on other sites More sharing options...
Supporters M_P Posted September 21, 2013 Supporters Share Posted September 21, 2013 Don't forget the cost for the regulators and air hoses etc Link to comment Share on other sites More sharing options...
Hudson Posted September 21, 2013 Share Posted September 21, 2013 I've got an A&K SR25 too, and had the idea of using a normal V2 gearbox with the G&G hop unit; but when I tried it I couldn't get them to marry up properly.*Theoretically* They should do, but in practice it's another story. :/ Link to comment Share on other sites More sharing options...
Supporters Airsoft-Ed Posted September 21, 2013 Author Supporters Share Posted September 21, 2013 Damn, that's bad news for my plan... I'ma have to borrow a V2 g'box and see if I can get it to fit. The Grange say they'll custom fit it for me either way, but I'd rather it just fit... Link to comment Share on other sites More sharing options...
Hudson Posted September 21, 2013 Share Posted September 21, 2013 It'd probably fit with a bit filing/cutting. If you're interested in the hop unit to try it; I'd sell mine. Link to comment Share on other sites More sharing options...
Supporters sp00n Posted September 21, 2013 Supporters Share Posted September 21, 2013 i take it the gearbox and hop are further apart? if so why not just change the air nozzle to a longer one? Link to comment Share on other sites More sharing options...
Supporters Airsoft-Ed Posted September 21, 2013 Author Supporters Share Posted September 21, 2013 i take it the gearbox and hop are further apart? if so why not just change the air nozzle to a longer one? I will need to do that, I'll need a long hop and a longer air nozzle. P* sell air nozzles specific to their FEs, designed to work hand in hand with the G&G SR25 hop units. So if I can get a standard M4 gearbox to work in conjunction with a G&G SR25 hop unit and air nozzle, then I'm onto a winner. Well, I'm not, 'cos it's so expensive I'll have to live on the streets for a millenium, but it'll be worth it in the end lol. Link to comment Share on other sites More sharing options...
AK47frizzle Posted September 21, 2013 Share Posted September 21, 2013 Is it really worth having a fcuking expensive hpa gearbox where you will have a massive tank and a dangling tube on your back? Or would it better to have a super high speed trigger response aeg gearbox? You could always go for a Madbull CO2 aeg gearbox. Link to comment Share on other sites More sharing options...

Or would it better to have a super high speed trigger response aeg gearbox? You could always go for a Madbull CO2 aeg gearbox. A p*s trigger response is quicker than pretty much anything you can do with a traditional gearbox and endlessly more reliable. The tank and hose would be no less of a hindrance than a single point sling- heck, you could even attach it to a sling to keep them in the same place. As for the madbull CO2 gearbox, it's madbull so it's probably not great and also they're not mentioned often- if they were worth it they probably would be, and they aren't as consistent. P*s are so good a large number of US sites have imposed lower FPS limits on them and other penalties. Link to comment Share on other sites More sharing options...

And.... do you just buy another tank or can you refill it with a even more fcuking expensive compressor? But yeh, I guess pneumatic powered devices are more reliable.

Supporters NickM Posted September 21, 2013 Supporters Share Posted September 21, 2013 You refill the tank from diving cylinders, if you are doing it right really you would need 5 or 6, but seeing as paintball already runs HPA you might as well go to one of their sites for a fill from empty and have a single diving cylinder you can use to top up from. About four of the guys on my team are thinking about getting P*s and it was the filling issue that was stopping us, but clubbing together to rent a cylinder for the day isn't that bad, £15 for a day from a local dive shop. Or buying a cylinder is the other option but at £170 then regular testing costs and filling charges that's probably not sensible. Would be better if more people were doing it and sites got behind HPA setups. Link to comment Share on other sites More sharing options...
Supporters Ian_Gere Posted September 21, 2013 Supporters Share Posted September 21, 2013 I did a post somewhere, it has most common air nozzle lengths I was thinking we need a database of nozzle lengths a month or so ago.

And.... do you just buy another tank or can you refill it with a even more fcuking expensive compressor? But yeh, I guess pneumatic powered devices are more reliable. Filling the Air tank can be super cheap. My uncle has an old Soviet PCP air rifle,and he has a little pump for it. The pump can be attached to a scuba diving tank or a paintball air tank,which P*s use. PCP air rifle pumps are usually pretty cheap. The P* engine is super reliable,very little moving parts and simple mechanisms,much less maintenance needed than a normal AEG. Ed,you can also get Daytona gun kits for a little bit cheaper than P*s,but I don't know if they can fit SR25s. a Daytona gun kit is basically a HPA powered GBB,with epic recoil and next to zero cooldown.

Supporters M_P Posted September 21, 2013 Supporters Share Posted September 21, 2013 I think Daytonagun closed down in the last year at some point. But they can fit SR-25s as far as I know- there's a guy on a few other forums (arnies, zeroin etc) who has one in one- G&P I believe though it could be ares, one of those two though for sure.

Unrustle_Thine_Jimmies Posted September 21, 2013 Share Posted September 21, 2013 EDIT;Saw a few older arnies threads and a world airsoft news page. Closed. Damn shame. Some other guy in the US is making some stuff based on DG kits,a company called OPForce or something.They seem a bit shady though. Link to comment Share on other sites More sharing options...
