2x 1/2" pipe coupler
8" of 1/2" pvc
8 1/2" petg thick walled
Small tubing roughly 1/2" like barrel tubing. (barrel to Mavrick)
thin wire (mav AR spring)
Hack saw perhaps.
Stepping bit that goes up past 1/2"
As for internals the gun is still pretty much stock. I have relubed the plunger with silicone lube and also sealed the top of the plunger tube to the body of it. No structural reinforcements were done because everything internally was still stock.
Externally I hacked the front of the plunger tube down to about 2"
Knowing that I was going to be using epoxy I wanted to give the adhesive some area to grip onto so I used my pipe cutting tool and cut some grooves for epoxy to sit in and get a solid grab.
I also scored the hell out of the coupler as well. I wanted to make sure this wasn't EVER going to go anywhere. I've had plumbers goop fail in the warm weather and didn't want to deal with that.
I didn't get a pic of the building of this part but let me discribe what I did.
After a couple test shots I found that the gun liked to suck darts in. So to prevent a dart getting sucked into the plunger tube I made a stopper.
To build this I took the end of a barrel cut from the turret on the mav that I had left over when I went to petg on it. (Yeah I save random parts) I used about 1 1/2" and cur some groves into it. in one of the groves I drilled two small holes and threaded an AR spring from a MAV thru it and wound it tightly around the outside of the tube. I used some hot glue to hold it all in place while I snipped the excess wire. Then I pressed the tube down into the original barrel of the BBB. a little filling of hot glue around the outer lip gave it a firm seat and it isn't going anywhere.
I also didn't get pics of the barrel building but heres a quick how to. Take your 8" piece of PVC and use the stepping bit to the inner diameter of it. drill it out only a little to make a slight slope in the end of the PVC.
Now take the PETG tube and along the length every inch or so wrap a single go round of electrical tape.
Now take a lighter or some heat source and heat one end of the petg you want to flare this out slightly.
Cover the exposed parts of the tube with plumbers goop. Now the side of the PVC that you tapped and the end of the PETG that you flared out is going to be the side of the barrel that you load darts. So slide the petg into the PVC accordingly. I reccomend twisting this as you go so the goop can get a good seal on every side of the petg. this will help strenghten the whole thing and keep the petg from shattering inside the pvc if you hit it on something. It makes the barrel more accurate as well.
When you get the petg slid all the way in you will have some excess goop to deal with. Clean that off without allowing it to fall into the barrel. If you get it in the barrel you are finished.
Now on the other end of the PVC you cna toss a coupler on there for looks as well it will help protect the small about of petg that will most likley be sticking out the end of the barrel.
While I had the shell of the gun open I decided to do a lil by way of cosmetics as well.
I don't like the front sight of the BBB as most people don't. So I hacked that off with a hacksaw. Now I hate he hole that leaves in the gun so I make a panel to cover that.
This part is rather simple. Take some thin acrylic or polycarbonate sheet that you can cut with shears and cut a panel the right size to cover the whole area. and then cut that again right down the middle. Take some plastics cement/Weldon #16 and put a little on the outsides. with the two halfs of the gun shell toghether glue and hold in place till it dries. Then take the gun apart and apply some more cement on the inside edges so that it gets a nice filling. When this dries it is as much a part of the gun as anything ever could be. after it dries you will want to take a hobby knife or utillity knife and clean up the outside edges.
And thats it for the modding. All thats left is paint.
And heres the end results.
It gets pretty decent ranges. I guesstimate about 70-80'
