Ok, so I wanted a cheap, fairly durable springer to back up my X-bow, so I swung by Target and grabbed a BBB. Here is what I wanted to increase: efficiency, range, and durability. Some of these ideas originated else where, but I’m bringing them all together along with some new stuff.
Materials:
” PVC
5/8” PETG
OMC’s PETG
Hot Glue
Super Glue/Fishin' Glue
1. Open ‘er up and take out the orange barrel piece, and cut down the barrel piece, like in the picture. You can cut it down further, but wait until later in the mod to do so.

2. Create the coupler: Since I’ll be using OMC’s PETG I found some 5/8” PETG that works nicely as a coupler when sanded out a little bit. So sand out the bigger PETG and then nest it in some ” PVC, like so.

3. Glue you coupler into the side of the orange piece, I’m using fishin’ glue, but super should also work.

4. Fill the orange piece with hot glue around the outside of your coupler, make sure it is flat and level with the PVC.

Here is a picture of the barrel in the coupler with a dart

and without dart:

Here is the barrel nested in the coupler:

5. That is the mod, from here you can do some appearance work, add a new spring, reinforce it, or a paint job. I did THA's spring replacement and reinforcement mod and cut off the front scope. I also plan on adding a removable stock in the future, and some more appearance work.

And thats it. What do you guys think? Good, bad, ugly?

I like it but......... Inline ! Inline!

BBB's are really cool guns to have an incline on.

I think I'm going to try your mod and put that inline on.

I like the seal. Nice variation.

What kind of ranges do you get?

Thanks for the compliments so far.

I don't think you could really put an inline clip on this thing unless you have super skinny darts.
I've been messing around with inline clips on my X-bow, but haven't really figured out something that works for me yet. I need to PM Carbon.

I didn't really have time to get good accurate distances. I was able to hit my garage at about chest level from ~70', but I think I might be able to squeeze a bit more out of it.

OMC's petg is 9/16", it fits slightly tighter than 9/16" brass.

Beautiful mod right there. Very clean looking, but you should have filled up the dead space with hot glue like Joeyagrl's big bad sexy mod.

The chances of one person taking a bomb on a plane are one in a million. The chances of two people taking a bomb on a plane are one in a trillion. So if you're scared of a terrorist attack, bring a bomb on a plane.

If you would have read the mod, or even looked at most of the pictures, you would have seen that I did.
