[I’ll get a pic. Up here when it’s done]
It is an Airtek 2000 integrated into a Big Bad Bow, alike to the Crooksbow but with some improvements:
-You don’t need to grow two more arms to operate it.
-The way I did it maintains the front handle (my preferred method of cocking the BBB).
-Pump relocation allows it to be more compact.
-I can take off the breech easily.
-It’s purple.
-It didn’t cost whatever the Crooksbow sold for.
*Credits* Forsaken Angel’s Angelbow write-up helped with the BBB portion and the Crooksbow is kinda what this is based off of… also Tatumbull’s AT2K thread helped with the 2K protion. You have been credited, congratulations..
I admit this isn’t as easy as Maverick AR removal, here’s a list of the materials required to duplicate this:
-Big Bad Bow
-Airtek 2000 (with shell)
-(2) 1/2” PVC elbows (one of mine was threaded but it doesn’t make a difference)
-1/2” PVC
-¼” Vinyl tubing
-1 or more tubes of epoxy putty
-1/2” CPVC
-1/2” CPVC elbow
-9/16” Brass
-17/32” Brass
-19/32” Brass
-PETG
-Amazing goop
- (2) Ace #49 springs
-Hot glue and hot glue gun
-Small piece of wire
-Paint
On to the mod
Stock BBBs like this one are increasingly hard to find, this one I got from Venom213. It was in good shape when I got it, just a little rust on the screws.
Taking it apart is simple; remove the screws out of the front half and pull the orange cap off the back sight, then remove the screws in the back as well.
The internals lain out:
I’ll start with the barrel part; I cut the stock barrel down to 3/8ths” and then drilled a small hole through both sides at the base of the stock barrel and super glued a piece of piano wire through it as a dart stop (I use a similar setup for my other two BBBs).
Then I put some weird ½” PVC coupler on with 5 min. Epoxy, I had to sand it down a little to fit.
I replaced the stock spring with 1 AND ½ Ace #49 springs (the other half went into another BBB), the same length as the stock spring.
I’ve used epoxy putty and washers to reinforce the spring rest on BBBs, I think this one has Epoxy.
I put it all back together at this point ad gooped 12+7/10ths” section of CPVC to the rear bar thingy, I had to dremel the screw post that was in the way out of existence. [Didn’t take a pic of this..]
The breech, Layout of the parts:
List of stuff in the pic:
-1/2” PVC outer layer (8+3/4” long, a cut 2” long ¾” from the end to 2+3/4”, another cut 4+1/2” long from 2+3/4” to 7+1/2” [Initially I wanted the PVC outer layer to cover the Brass when it was extended but ranges were unsatisfactory, so I cut it down])
-19/32” Brass (cut the same as the PVC)
-9/16” Brass main barrel, 8” long
-9/16” Brass stub, ½” long
-17/32” Brass stub, just over ½” long (not shown, it was a later addition)
-½” CPVC section, 1+½” long, cut to fit over the 9/16” (sideways)
- ½” CPVC elbow
[My original breech design sits at the side, it didn’t work…]
Putting it together was simple; goop the stubs together. Then goop them into the back of the 19/32” piece (the back being where the coupler attaches) and goop that assembly into the PVC so that they match up and wait for it to dry. After it was dry I slipped the 9/16” piece in and gooped the CPVC chunk to it after test fitting the movement and making sure it was correct.
On the BBB:
I could have stopped there with a decent primary that hit 70’, but I decided that I wanted a great primary…
The AT2K portion everyone knows what an AT2K looks like stock, so I won’t post a pic of it. I took and 2K and made it look like this:
(Tatum’s 2K thread helped a lot with this) Basically I took off the goo-gauge, replaced the tubing (in this case from a magstrike), replaced the handle with a ½” PVC elbow and some ½” PVC and removed the original air output thing.
I cut the turret down to near it’s base and put some PETG on the back for the air output, did the basic airflow mod, then I put 1” pieces of 17/32” Brass into the turret stubs and gooped 6” of PETG over that.
The shell had to be cut to do what I wanted to do with it..
^Why such an odd cut?
This was all really straightforward to me:
-Put the two on a flat surface
-Apply Epoxy putty
-Wait for it to dry
-flip over and add more putty to the joint
Result:
I cut a PVC elbow to fit over the end of the pump,
And a chunk out of the other half of the 2K shell so that when I screwed the other halves of the now attached shells, the tubing went through the shell so that the pump was on the outside:
I then Epoxy puttied it all together (while staying on the lines of the two halves):
Then I rigged a trigger for the AT2K, meant for the tip of my index finger and maximum opening of the valve.
At this point I tested it, This is what it looked like:
