Well, I've been out of the game for quite some time. I'm re-kindling the fire of Airsoft Sniping now out in California and well. I'm having something of a problem here. The problem being that I have incredibly low power it seems long range. I'm lucky to get maybe 20-30 feet before the hop up almost shoots it down. I've tried adjusting in large increments both ways and have yet to receive any justice to the problem at hand.

Here's what I'm shooting, essentially:
- Laylax APS Cylinder
- Laylax APS Piston & Piston head
- Laylax APS Taper Cylinder Head
- Laylax APS Spring Guide
- Laylax Reinforced Bolt Handle
- Laylax PSS2 Zero Trigger
- Laylax Power Accuracy Cup
- 400mm 6.01 Edgi Barrel Ported
- Promethues red Hard bucking
- Big-out H nub
- Laylax 150 spring (About 500FPS)
- PSS2 Aero Chamber

Long story short it's got the upgrades, almost $1000+ worth, but I'm not getting desired range right now. Or any for that matter.

I've also got a PDI Hop up at my disposal here that I could try and switch out, but I don't think it's the hop up unit itself, maybe just an adjustment I might have done incorrectly. Worst case scenario I take it to Airsoft extreme in San Diego and they charge me some rediculas rate and tell me more is wrong with it than it really is and I walk away mad but with a working weapon.

Thanks again for any help I can get here,

Change to the PDI chamber, and check the bucking for ANY slipperiness.

Also, check the bucking itself for any rips or tears, the nub could be coming through the bucking, that would remove most of the hop.

Definitely will give it a try. I don't know man, the PSS2 Aero Chamber worked amazingly for me last time I had it, but maybe it's time for a change back to the PDI. I'll edit this post when I've finished doing that.

I am assuming that you had the rifle stored while you were deployed?

You may want to check the rubber on your piston, cylinder head, and your bucking.

Over time they will harden and shrink a little bit. This could cause some serious compression problems with the rifle.

I am sure that the spring wasn't compressed over the storage time. But you may want to think about replacing the spring all together.

But I would start with a good lube and see what happens.

Hm... Well I've got even more great news, so as it turns out this rifle being as old as it is a bit more is wrong than expected. Anyone know of some great sites to get some of the harder things to find? I'm looking for some replacement screws for my Zero trigger to mount to the upper receiver, as well as a new screw to mount the mag catch to the barrel.

Also, I need a new outer O-Ring for the PDI hop up as well.

If anyone could provide me with exact sizes/spacing for these pieces as well that could help. I'd like to have this piece back in action soon, so I know if anyone can make this happen it's ASF.

 

[woogie]

I would head to a hardware store man.

Get a pack set of various o-rings. That way you can find the one that you need, and have a few extra for other things.

And then head to the small bolt section, and find one that is a little bit larger than the one that was in there. I would also look at getting a small tap and dye set. Find out the size of your bolt and tap your reciever.

Many places will have those litlte drawers that you can buy single bolts in. I know lowe's and hope depot have these. Take your trigger mech screws and go searching.

I've been there before and done that. The problem is I find myself having to custom grind the screws down as well as do other things like stretch the holes out. My problem is mainly the mag catch one. For those who own an APS-2 they know what I'm talking about, the problem mainly being that sure the size fits, but the head is usually too big, and doesn't allow the mag to seat in there 100%, which leads to dry fires.

I'll make a short video or something and put it on Youtube describing what's going on, along with a small video of what's happening when I shoot and I'll have it posted up tomorrow. When there is actually daylight out.

I was going to edit, but I switched out the PSS2 Aero Chamber for the PDI Hop Up. I used the Big out H nub and installed it correctly, but here lies a new problem. Maybe some tweaking can help:
So when I shoot what seems like any angle higher than 90 degrees (Dead straight) the weapon doesn't fire completely, get kind of a dull sound. All the works happen properly, but the only downside here is that the bb doesn't eject. I rack the spring back again and then it shoots relatively fine. The only problem that I'm having here obviously is the occasional misfire. Anyone experience the same thing/know how to fix this?

Thanks,

It sounds like the bb is not getting into the chamber properly. I would check the cylinder head for any discrepancies, and then make sure that your mags are in the gun completely - that has happened to me when I got some snow on the mags and they did not get into the well completely. ALSO, check the o-ring in the PDI chamber that goes around the cylinder head and bb - if that is in the dumpster, that would produce such an issue.

 

[mosin]

Are you talking about the outer O-Ring? Or the one on the inside there? Because if you're talking about that outer one then that ripped on me a few days ago. Also, all I'm doing is dropping the bb's in one at a time when the bolt is locked and then I push it in. Do you think that's the problem there?

 

[Cheese Man]

I mean the one that is inside the actual chamber. What are you using to retain the arms?

Also, when you fire the second time, when it works, do 2 bbs fly out, or is there just one?

 

[mosin]

To answer the questions:
1. Right now I'm not using anything, but I plan on using a rubber band to hold the arms down. I know that you should have an outer O-Ring but I tore mine (As said earlier) but I don't know how the pressure would be a problem.

2. I don't re-rack a new bb unless the first was already shot. So to answer the question all I do if it doesn't shoot is rack a dry round (Air) and then I'll usually see the distance I was looking for, along with power and (once it's tuned) accuracy.

 

[Cheese Man]

I have no clue. Could you post pics of the chamber, the side that the cylinder head goes in, as well as the cylinder head?

 

[inthetallgrass]

By a PDI repair kit from X-fire. Also the PDI hop up should come with a mag catch screw.

Quite the necro post there. :-/

And the PDI repair kit does not come with a mag catch screw, it least not in my experience.

I just bought an APS-2, I'm going to be installing basically all the same parts as you. I will see what issues I come across when I go to install mine. It sounds like everyone has listen most the things that could be wrong.
Have you relubed your gun since you got back? The cylinder head could be damaged and cause it to be not shooting enough air. Something could have gotten into the gun aswell. The hop-up could be the flaw. The bucking could be getting old(er) than it was when you left, causing it just not to work anymore. Those are my opinions.

 

[aydonmill]

When I changed to my PDI chamber I found out why my stock hop-up wasn't working... The hop-up arm clean snapped in half, this could be why the hop-up doesnt work.

 

[hoggie]

Okay, I have the same upgrades as you, and i'm getting like 225+ range. Check the bucking, clean the barrel, look at the sear set, check the BB, check the cylinder head, check the beginning of the hop-up unit, and inside it. Dust, grim, animals, somehow could have gotten into it.

 

[aydonmill]

Yeah definitely need to watch out for those animals
