The "Stop being lazy and finish my SPR" Thread

[Herz]

(Forgive the horrible writing, It's 9:35 and I've not slept in a good day or two :p I'll come back and edit this to look a bit cleaner soon.)

Well, After an ungodly long Hiatus from Airsoft it looks like I've caught the bug again.

Just recently traded off a Paintball gun for a KWA M4 and decided to dig out all my old guns and gear.

There she was... The money pit itself.

09 Classic Army M15A4 (Back when they just got the new gearbox's and did a solid 380 fps out of the box with all the fancy workin doodads like the charging handle) With a swapped front end in favor of SPR Mk12 Mod 0 furniture. A 6.03 Prometheus TB, Firefly bucking, Guarder hop-up and an Ajax STS System.



SPR on the top, New KWA in the center and my old CA CQB Seal on the bottom.

So, With even more searching I started feeling out and finding the rest of the bits.

Guarder infinite torque up kit (SP150... Yaaaay)
Systema Magnum Motor
Infected Airsoft Mosfet
King Arms 8mm Gearbox

My apologies for not snapping any pictures of this process, But no access to a decent camera and me being in a bit of a giddy rush. I forgot :/

So for the past week or so I've been fiddling around slowly preparing the gearbox for this monster, Slowly shimming to perfection and breaking in the gears.
Running the Magnum on an almost dead 8.4v until it was broken in (Along with breaking an old pinion driver trying to remove the Magnums pinion... Yay.)

Then, Thing's slowly neared completion up to the struggle of this morning. Forcing an SP150 into the gearbox after a good greasing of gears and other bits. Wishing I had more hands as I had to struggle to keep the spring guide from flying out and fit the CA M15 trigger spring back inside the gearbox (I swear CA... I wish you designed that slightly differently.)

Alas! The gearbox was complete and together. Ready to go out and test fire after such a long wait.

"Vree-Vruuuuh... Vree-Vruh..." Look's like the battery might need some charging.

-Sometime later-

Vree-Vruuuuh... Vree-Vruh..." Still the same problem... Just half turning the gear's slowly half the time until it fires.

I tore the stock and grip off thinking maybe I had the shimming too tight, Maybe the motor was adjusted too high.

Playing around pulling the trigger from different angles I noticed the motor would only spin half what was needed at certain angles and if I sloooowly sloooowly pulled the trigger it would make its full rotation and fire the spring perfectly.

Then it struck me... I forgot to clean and redo my contacts while the gearbox was torn down.

Welp. Bit of a let down but it looks like I'll be diving back into the gearbox sometime soon to give my contacts a cleaning and see if they need replacing.

Hopefully I'll be updating this thread soon with progress and eventually statistics on how the rifle performs.

Stay tuned!

What battery were you using when you tested the gun. With that big if spring, you may need to use a 11.1V or a 10.8V to get the spring to move...

[Herz]

Nah, It's an old Intellect 9.6v 3600. It's doing alright to keep up with the Spring. If I hold the trigger just right I can get a row of shots since I can make the contacts connect. Had the same problem using different motors/batteries with the contacts so I just need to tear it down and give it a once over to see whats going on. Most likely just needed a clean or the contacts bent back I hope.

[Fridge Gnome]

That might be it, but I would try a new battery. I had a problem with my G&G firing a few shots and then stopping. It ended up being something with the battery.

[Herz]

Nah, Just turned out to be the contact having issues connecting from the trigger. Pulled the trigger contact out, Flipped it around and put a tiny little spacer in the back. No issues at all now and a slightly shorter trigger pull ^_^

Of course... Only real issues being the plastic safety latch on the gearbox broke which I need to fix. Along with the screw for the mag catch deciding to strip itself. So those two bits and the SPR should be done for good.

So far the gun has no problem nailing an owl statue situated in our garden a good bit away from the front of the house with .28's. A few stray flyaways here and there but I figure with a bit more work here and there and she should be right as rain. (not to mention needing to zero my scope in. Tired of aiming high and far to the right.)

I'll give the gun another once over, See if I can square away a seal issue I'm having with the air seal nozzle and see about getting those parts needed.

Unless of course someone has a spare CA or clone mag catch and gearbox safety they'd be willing to let go cheap? :p

[Fluffy Boy 32]

[Herz]

Aye, sadly I only have .28's handy for right now Pending on if I splurge or not on an ambidextrous mag catch I'll prolly order a set of better BB's to run.

Thankfully with the .28's I'm punching through coke can's and accurately hitting a coke can sized target situated in the garden. Should be able to double or get a better grouping once I stop being lazy, Fix my problem's and finally zero my scope in. (Aiming high and to the right is getting veeeery old)

[Herz]

Bit of an update, Guns all back together and firing like a charm.

Only issue now is to find a gearbox safety and shes all set


Spent most of today zeroing in the scope and testing her out. Hella windy but still accurate.

Couple of better pics of her









Gonna try and hopefully get a couple of vids up pretty soon of her in action. Hopefully I'll have the barrel and bucking broken in by then :p

[trevorst]

My WA is looking good with those grips

[Herz]

[Herz]

Figured id bump this up. Guns still as strong as ever. Just lacking semi only, wiring my mosfet and some redone wiring.

Should have more info and vids up soon. Still havent fielded this gun either.

[Herz]

Safety fixed, infected armory mosfet wired up with xt60s and semi only enabled.

Should have a few pics up soon aslong as a small tutorial on wiring the mosfet and my semi only mod if needed.

Now to just order some r hop patches to replace my firefly bucking >.>

[Herz]

Super disappointed in the Infected Armory Mosfet. Replaced it with an Extreme-Fire SW-Panther and couldnt be happier! Retired the IA Mosfet to my MP5.

Now for a scope riser to get a better cheek weld and eye relief then some work on r-hop.

[ShawnB52]

What didn't you like about the AI mosfet? And I assume both the AI and the extreme have active breaking?

[Herz]

The IA is perfectly fine for a milder build. It had issues with the Magnum motor and torque gears.and just overall slowed down the trigger response.

Now its been shown on most forums IA mosfets are like this, but mine was bought before this was proven. Much much happier with the Panther.

The Ia Will do fine with mildy built AEGs but it seems to suffer with higher end builda.
