HPA retrofit on ACP/2: Install

Ok, while everyone says it could be done, i haven't actually seen anyone do it, so here's some pics.

For parts we have:



Dummy 12G from Palmer's Pursuit

90* macro fitting

12" macroline

1 penny

Custom Product rail

Custom Products on/off ASA

HPA tank...more than likely a 13/3000 or 22/3000





First thing i noticed with the dummy 12G is that it was very well made. It's solid, not hollow and just has the 1/8thNPT fitting and a hole from the fitting to the nozzle drilled into it. Has some feel to it so it's not cheap eventhough it only cost $15.

The problem however is that it is slightly shorter than a normal 12G due to the top being flattened

http://www.pix8.net/pro/pic.php?u=11130S5RAi&i=1058337



Not a big deal. Here;s what we need for install. The 12G, a penny, and macro and a fitting

http://www.pix8.net/pro/pic.php?u=11130S5RAi&i=1058333

Simply slide the 12g into the gun and postion the fitting hole on whatever side you would prefer

Next, put the penny in on top of the 12G. You'll notice it fits perfectly in the bore and is thick enough to make up for the small smount shaved off. You could prob make something but pennies are cheap and easily found. Make sure you use a copper penny (pre-1982) as they are softer and won't corrode like the new zinc crap. Put the cap on and tighten it up

Next, screw in the macrofitting. You can see it's a tight fit to the side. If you have access to a mill, you could prob enlarge the window slightly by maybe 1/8" for a little more room

http://www.pix8.net/pro/pic.php?u=11130S5RAi&i=1058338

Finally bolt on the rail/asa or whatever combo you will be using. I had to get longer screws for the rail to reach the threaded inserts on the ACP. Unsure of the side though. I beleive they were 10-32's but not sure. This setup is off my other paintball gun. Since i can only use one at a time with the HPA, i decided to just use my existing setup. If i ever want to play with the ACP as a secondary, i would convert back to use the 12G cartridges anyway.

Final shot. I used the 68/4500 just for testing. It's way too heavy to play with flipped this way. If you flip it with the tank as a stock, it does feel nice. A grip attached to the weaver rail would help and you would then have a sort of machine pistol. I'll be ordered a 13/3000 soon.

I've taken shots with it already. It's leak free, and just by the sound and by viewing it in action, i could tell you the velocity is definitly higher than with the cartridges. DO NOT shoot anyone like this until you chrono the gun. SInce work will keep me away from playing this month, i don't know if i will be able to get it chronoed anytime soon, but definitely be aware of it.

Now, i just need a hopper adapter

Actually if you flip it around, it's not bad. You just need a forgrip that will mount to a rail and you could have a mini-carbine.


But there is no need for a tank that large when you have a 10-shoot clip. A 12/3000 is all you would need

I am doing the same thing, for the puncture pin do you still have the o-ring? Cause mines gone and now its leaking like crazy. I'm going to try again with a couple pennies to lock it in though. Do you know what size those o-rings are?

I don't think mine had an o-ring at all. I'll need to check though
