Well, since I decided to start finishing up modifications to the APS I purchased used. I thought I'd start a thread to keep track of just where I screw it up!
When I bought it, it already had installed the following;
-First Factory 3-Element NEO Piston
-First Factory - PSS2 150 Spring
-First Factory Zero Trigger
-Guarder Ball Bearing Spring Guide(9mm)
-Guarder Taper Cylinder Head
-Guarder Stainless Cylinder
-Guarder steel bolt handle
My plans to install in near future ((as parts come in));
-510mm 6.03 tight bore
-PSS2 130 Spring ((drop FPS so it stays in regulation limits with the tightbore))
-PDI APS Adjustable Hop-up
-Guarder APSIISV Barrel Spacers
Now, to accomondate the inner barrel, I will have to increase the outer barrel length. I have two options, I can;
-get a simple one piece extension milled ((one peice with threaded ends to match barrel diameter
-build a custom silencer mod for the front
Those two ideas I am debating and going to look more into the logistics of both, but at the moment I am leaning at a cleaner look with the simple extension.
Now, while I'm looking into all this, I've taken the APS down, and found that there were some screws slowly coming loose. After wrapping teflon on the larger screws and some locktite on the smaller the screws should stay in place. This as solved the issue I had with the bolt locking drawn.
Stalker has pointed out one idea to me that I've already started on now, and thats filling the hollow stock. There is a good little ring to the gun when fired and so I am filling in the empty space with expanding foam.
Now all I gotta do is wait for it to cure and then I can cut out the excess and refit the barrel. Once that is done I am going to record the sound to see how much different it has made. ((already recorded pre-modification)).
Okay, I got a before foaming video for the sound of the APS before filling the stock.
This is the before:

And this is the After:

There is still a healthy 'thack' but that ringing is gone.
- Silencer Mod -
A quick idea, based on yet another of Stalkers ((This guy is making original thinking hard to claim I tells ya.))
Lead to a walk through of Home Depot. $10 later I had the materials needed to make a quick silencer up for the gun ((Sorry for large pic))
1 piece 1 1/4" aluminum pipe
1 piece 1 1/4" shower curtian rod rubber ((pounded into the end and hole drilled to cap))
6 screws
- Paint -
Two coats of OD, and a bit of ghillie work to create the above look. Ghillie still in progress.
- Inner Barrel and Hop Up -
Okay, first, beer, LOTS AND LOTS OF beer with advil required for this damned mod. Also, that little spring that comes with the PDI Adjustable hop up that they say to tape and put on the top, yeah throw it out and later drill a hole and tap it for a small screw, MUCH EASIER!
The above aside, I installed a 550mm 6.03 tightbore inner barrel that I picked up off ASC here, as well as an adjustable hop up from Redwolf. I chronied it after getting it out to a range that I could test the range, for once something was right and the gun shot true at 100 ft. I'll tweak the hop up a tad later on, but it shoots just fine for now. The FPS came out to hover at 440FPS which was a relief as I had expected a MUCH higher FPS out of the gun than this.
Anyway, the whole reason you guys clicked this link,
- MORE PICS! -
And of course, what it started out as. . .
The bi-pod that was on there is for the armalite, as I intend to get a pivot bi-pod for the APS to paint up and stick on.
Final appology, sorry that my camera sucks :P. It couldn't picture the 416's and 249's that should have been strewn about.
