I love single shot spring guns. They are more simplistic and usually more reliable than most air guns I've ever used. But I think that it is safe to say that air guns have far more versatility when It comes to potential. Distance potential, ROF potential, and integration potential. The thing I love about springers though is the fact that no matter what size the springer, It always has a faster priming time than air guns. But enough comparison, they become great when paired together. A pump shotgun as my primary, and a 2k as a back up shot.

Cosmetics are a very important thing to me in nerf guns, so I always look to keep a very clean look with all my mods, so after some thinking I found the perfect way to integrate a 2k into/onto a pump shotgun.

Things you need-
- pump shotgun
- airtech 2000 internals
- a dremel
- your favorite type of adhesive
- 3/8" tubing (I'm not 100% sure, because I did this mod a while ago)
- hot glue
- a metal pin
- plexiglass

First off, I did Angels level 2 shotgun mod, except for adding a spring to the trigger which I did differently to make space for the tubing. Angels mod can be found here.

We are primarily going to be working on the stock of the gun, so I don't have any pictures of the front in this write up.

First you are going to need to make a "cross" cut in the back of the stock.


Next, you are going to need to make the hot glue in the handle sort of like angel did, except for where I positioned my tank, we need space in the back, So you are going to have to glue a metal pin to support the spring and still be able to have space in the back. I hot glued the pin a little, let it cool, then used some zap-a-gap and then repeated the process a few times. DO NOT ADD HOT GLUE ONTO WET ZAP-A-GAP, IT WILL CREATE TERRIBLE FUMES, I got some of the fumes in my eye once, and I had a sharp buring pain for about five minutes.
(This pic isn't too great.)


Next, you want to cut off the end of the pump handle at a slight angle, and replace it with some plexiglass. (or you can skip this step if cosmetics don't mean as much to you.)




Next you are going to need to pick a spot for the tank, I chose on top of the gun for reasons I can't explain, I just bought another pump shotgun and I'm going to put it on the bottom where firing it would be much more comfortable. I initially glued it with zap-a-gap and the used epoxy putty for support.




Now you need to make a hole in the shell of the gun for the tubing to pass from the pump to the air tank.


Now you can put in the pump and put the tubing through the hole.


Next connect the tubing to the air tank.



Now you have a 2k as a back up shot for the pump shotgun that is very cleanly done, the pump is not sticking out in weird places that make it look very "fugly".

Sadly, this gun is still unfinished due to the fact that I cannot for the life of me find any neon blue paint anywhere, but all other components are finished and have been tested.




Here's some more pics for the heck of it.

This was just a small experimental project that I decided to do a few months ago because I wanted a shotgun big blast, but I wanted to be able to use a regular barrel also.

The material you will need are,

- hacksaw and mitre box
- 1 1/2' feet PETG cut into six 3" sections
- e-tape
- 1/2" pvc
- buttloads of hot glue
- plumbers goop
- the top part of a mav turret
- a 1 1/2" to 1/2" reducing bushing and a big pvc fitting that one side is threaded and the other side fits the
reducing bushing loosely (If anyone can help with the name, that'd be great)



First, we are going to work on the barrels.

This first step I do not have pics for, so I will try to explain it. Take the top part of your maverick turret and
place it on the top part of the big pvc thing. (the threaded side) Take one of your 3" lengths of pvc and put it in one of the turret holes. half of it should be sticking out the top, and half should be sitting on the bottom lip inside the pvc thing. make sure your PETG is straight and mark with a sharpie where you can first see the PETG coming out of the turret. Measure from the bottom part of the PETG to the mark and write it down.

Next, take your marked piece of PETG and wrap a few layers of e-tape just under the mark. It should have a semi-snug fit in the turret. take your remaining pieces of petg and measure out what you wrote down before, and do the same thing until you have done it to all six.


Here they are in the turret.


Take a segment of 1/2" pvc that is just as long as the part of PETG that sticks out the bottom put a little foam inside, and hot glue the foam in. while the glue is still hot, stick it on the little nub on the under side of the turret. This pic already has the barrels in it.


Now, once your pvc piece is on, you need to goop the barrels in. These NEED to be air tight, so it is critical that you use goop. Goop aorund where the tape is. Same pic.


Next you need to take your finished turret assembly and goop it into the top of the big pvc thing, leaving no space where it is not gooped. (Use excess amounts of goop, the you can even it out with your finger.)
leave it to dry 24-48 hours, but don't let your barrels move around while they are drying.

Once that is dry, bust out your hot glue gun. you will need tons of glue sticks for this. you need to put glue in all the empty space around the barrels. I know, I know, it's sexy.


Now take your reducing bushing over to the mitre box, and cut off half of the back end. This is essential in letting the air from your gun flow to the barrels. Once you have cut it in half, but loads of goop around the sides, and then slide it in the back of big assembly.


Now all you need to do is glue a stub of 1/2" pvc into the back of the shotgun turret and let the whole thing dry.

Pics of the finished product.


On the gun it was made for.

On a SNAP.

The darts don't go very far on the snap, but the turret looks more natural on it.

I am pleased with the result of this turret. It took little effort and time, and is fun to use. It can be used with any gun that can output large amounts of air, such as titans, blast bazookas, national geo guns, possibly even the plus bow. I apoligize for the lack of picks in some parts, but it didn't strike me to take pics of certain things until after they were glued and stuff. Oh well, enjoy!

I always wanted a sm3k that shot megas, but I knew that micros are more commonly used. I came up with an idea to make the 1/2 barrels changeable with petg and cpvc.
This mod is for being able to use different barrel materials/types, not to breech load each individual barrel, you still load these from the top.

For this mod you will need,
- 8 cpvc couplers
- 8, 4 inch lengths of 1/2" pvc
- some cpvc
- plumbers goop
- zap-a-gap/fishin'/crazy glue
- e tape
- a hack saw and dremmel
- a pair of pliers

I found this gun at a thrift store and immediately got to work


Here are the guns internals


The main part of the gun that we will be working on is the turret. You need to pry off the orange cap on top before we can do anything to it. It should look like this


Next I just ripped all the barrels off with a pair of pliers, unscrewed the screws in back of the turret, and removed the blue barrel sheath.


I cut the remaining barrels down to about 1/2"


This part is a little bit tedious and annoying, take your 8 couplers over to a mitre box and cut 1/4 of the coupler off, not 1/4", 1/4 of the coupler


Next you need to cut 8, 1" segments of cpvc. Pipe cutters make this really easy. then put the 1" segments into the short side of the couplers and use some type of super glue and glue where the cpvc and the couplers meet.


Wrap e-tape around the small stubs of cpvc and cut the excess off with scissors.


Put a ring of plumbers goop around the bottom of the cpvc, and stick it into the turret. Do this with all 8, then put the blue cover back on



Now, on to making the barrels.

Cut 8, 4" lengths of 1/2" pvc, and 8, 1" lengths of cpvc. take you 1" of cpvc and put it into a coupler, hammer on the 1/2 pvc, then remove the coupler. I also sanded down the little "lip" left by the pipe cutters so it was even around the bottom.


Stick the barrels into the couplers and it should look like this. I also did the bic pen mod, and I put some etape
tightly wrapped around all the barrels for stability.


You can put some petg in the pvc, or use some cpvc directly in the couplers.

Ranges are decent:
Mega- 46'
Micro in 4.5" PETG- 65'
Micro in cpvc- 62'

Ranges are not as good as I would have liked, but I didn't plug the pump, and I measured in freezing conditions.

I think that this gun is decent a decent gun, I wouldn't use it in an outdoor war, but it would be great in an indoor war.

Here's some more pics for refrence when putting it back together.
