So this was in a lot of stuff I recently picked up. I realize there are probably only about 5 of these still in existence, but just for fun I wanted to rebuild it and see if I could get it shooting, which usually isn't too hard with an old STBB as long as all the parts are accounted for. I was also kinda curious about the makeup of it having a VM style feed and what appeared to be a Kingman style grip frame. So in the spirit of MCB and documenting old crappy paintball guns, here is a quick breakdown. I am confused on the name of this gun. Is it The Edge or the PG-1 Pro? Is PG-1 Pro the company? If anyone can clarify that down below I would appreciate it.
First off, bolt takes 015 orings, bottom tube and plugs all take 016 orings. The body plugs are actually the same thread as a tank valve, but they use 016 orings because they don't neck down to a 015 oring like with an tank valve. There was a little gasket between the frame and body, but I just replaced it with a 009 oring and it worked fine.
It is all metric screws. Mostly M4 or M5, nothing hard to find though. It didn't have a cocking handle and I had a little thumb screw in 8-32, so I did rethread that from what I think was M4.
After fully rebuilding it, it did surprise me. It was shooting 315 on a 800 psi output HPA tank with the velocity nut flush and the stock barrel with pretty small paint(.670ish). So I took another tank I have set at about 650 output for use with my Armson Semi and it cycled just fine with that and velocity was right around 300. I don't currently have a lower output tank set up so I couldn't test it at an even lower pressure. At the lower pressure it did have an issue cycling with a 3D printed detent. The 3D printed one was significantly stiffer than the rubber one it came with and was rubbing on the bolt causing it to not re-cock.
Bacci has one on his site in really nice shape and it appears maybe it came with a foregrip and a standard Spyder style bottomline (metric). This one didn't come with a bottomline so I grabbed a spare and put it on. barely fit, but good enough. And it is the Spyder screw pattern on the bottom of the grip even though I didn't snap a pic of it.
Takes VM barrels. tried a couple different ones without issue.
Also, takes VM style detents which is pretty obvious. Every oring in the gun was hard as a rock and fell apart and overall the gun was pretty dirty. But the detent it came with, although covered in all kinds of muck, was in perfect shape. It is just like a VM detent, but it is made of a rubber that seems very similar to the rubber used for a Spyder style detent. Wish all VM detents were made like this.
This is the little gasket that was between the frame and the body. It was still in ok shape, but it was kinda hard to get it to stay in place and the 009 oring just fit perfectly in that little hole, so I went that route instead.
The lower frames between a Spyder and the PG-1 are similar as far as internal components. I didn't remove all the components of each to compare side by side, but from just looking at them, It appears everything should be interchangeable. All the pins and the safety are in the same locations. The trigger and the sear look identical. The way they attach to the body is different so the frames themselves aren't interchangeable, but the parts inside seem to be.
Inside the body, its kind of a modified Spyder. The hammer is the same as a fat Spyder hammer, the bolt is similar, I replaced the cup seal with a Spyder cup seal, which worked just fine. The big difference is the valve, which is bigger. the lower tube is about 3/4" all the way through unlike a Spyder which has that step down at the valve. Front valve chamber is pretty big as you can see by the size of that spring. also means the front plug is bigger diameter than a Spyder, so you can't use a Spyder LPC on it, nor do I think you would need to.
PG-1 internals on top, Spyder on bottom. The bolts are the same up to the air inlet hole, you can see that the PG-1 bolt is quite a bit longer. This one was caked in old paint and it corroded the bolt significantly. Still worked fine though once cleaned up and got some fresh orings. But one of the oring grooves has some significant corrosion as you can see below. It also has an additional groove between the front of the bolt and the air inlet which doesn't really seem serve a purpose as far as I can tell, so I just left that one off.
