In the quote is a pic of the last pump action shotgun modification and below it is the one we will be working on.The spring can be strengthened no more either. I tried but the catch wasn't catching.
Yes it is the same one I put back on the table in disgust in the last video.
I mentioned The catch wasn't catching at all with a spring that was too strong. We will be working on that today as well.
Alright so some of the mods in this are still the same. These similarities include Double coupler system, stretching around the extension spring, 12" barrel of 9/16" and some others not worth mentioning things. To learn these look up original pump action shotgun modification in the mods directory.
Lets get started.
Complete the coupler mod as done in the first one but dont add 19/32" brass yet.
Now lets work on strengthening that catch.
You may not need too but find a bigger torsion spring. Look at the puppy I found!
Now take the trigger out of your gun and shave the square part part down untiil the torsion spring sits fairly flat against the trigger. Now cut your new torsion spring down to size . Keep one end long like I did. I would even suggest keeping the left side even a bit longer than I did.
Now are going to want to find a washer that has a small inner hole and a base wide enough to keep the torsion spring in place. Place the torsion spring down onto trigger than put down the washer then brown plastic washer . Now the screw you were working with is too small so now you need to find a replacement. I used and old longer screw from a Nitefinder. Maverick screws should work just as well.
Now take a peice of PVC and cut it down so it will fit inside the shell of the gun on an angle and as snug to the trigger assembly as possible. Take your tiniest dremel bit and put a large pinhole in the pvc close to the edge.
That long leg of the torsion spring is going in there. Now cut a small peice of CPVC and do whatever it takes to help keep the PVC snug in place. This part gets a bit tiring. Hold the two peices as snug as you can and hot glue the shit out of them! We cannot afford to have these peices come loose.
Now it is time to stengthen the catch even more. Cut a semi-strong small spring down to size and have it go from the trigger, under the torsion leg and into a wall of hot glue made by yourself. Glue the spring in place for extra security where it is not touching the trigger.
Here is a video of the trigger mech now. The video is kinda dark but you get the idea.
Catch mechanism.
Now that the catch is godly it is time to make the rest of the gun just as godly.
Lets look at the head peice of the gun. The winged orange peice.
The only difference this time the 19/32" will be sitting flush at the end. Bringing the dart closer to the action.
Fill in the voids with hot glue. This will increase air pressure and decrease wasted air.
Now for something original:
Go to the hardware store and pick up a sponge gasket. It is a foam rubber.
Now cut out a ring of equal thickness as mine and hot glue it on there.
Your gun now has two stopping points. The rubber will cushion/silence/slow the plunger head down at the very end of the plunger tube and this will help take stress off the other heavy duty stock rubber stopper at the back of the plunger which originally took 100% of the blow. Now remember there was a gap between the plunger head and the brown peice originally. You want to cut the rubber so its a bit longer than the gap.
Neat huh? This can be done to more or less all springers! This method works very well.
Now onto the plunger. I took off the two O-rings and added 1.5 loops around the plunger head with a peice of E-tape no wider than the place for the O-rings and then put back the O-rings. The seal is much better now.
We wont be using as much hot glue this time. I found that the amount of hot glue used before was tons and The old method keeps alot of tension on the plunger head at all times.
Fill the brown backing peice up with hot glue and then go over the flush level with the brown peice. Now take your knife and cut the glue so its flush and flat. Pretty much skimming the excess crap off the top. This will create a nice flat surface for your new springs.
Thats right I said springs.
Three springs to be exact. The stock spring, an industrial spring and a stock spring from a whiptail scorpion. (Yes they can serve a purpose.)
Now the gun is great so far but with this kinda strength we need to reinforce. Here are some pictures of what you should reinforce if you want your pump shot gun to last. The catch reinforcement was drawn in because I accidentally deleted the photo and I do not want to open the gun again.
Here are some spots I found that were great for additionally silencing the gun beyond what I had done before.
Now this puppy is strong,durable and silenced well.
Time for a range test.
Conditions. -1 degrees. just below freezing. (This brings down range)
Wind: Coming from the North I was shooting into the West. Wind sent darts about 4-5 feet max of where I was aiming. In other words not that strong.
Method of measurment: My favorite 200' tape measure!
Darts used: Red and Black stefans.
Surface: Cold grass.
The cold seemed to affect my darts. They got smaller meaning not as much of an air seal.
The first dart I fired was a 3/4" dart and it spiraled out of control and still hit 107!
So here are the ranges with the loose fitting darts.
Black 117'
Red 135.2' and 139'
The ranges with the two darts I had that were still fairly snug in the tightening rings.
Black 164'
Red 163'
I only had my measuring tape rolled out to 140' when the darts sailed further I almost shed a tear.
This is not a gun for weaker nerfers though. I am lucky my other hobby is bodybuilding. I can cock it fine but I asked one of my buddies to cock it and he had to brace the gun against his chest and use two hands but he has very little muscle right now so if you are athletic you should be fine cocking this gun.
The catch is very strong and will not fire even if the gun is dropped. This gun does not have a name yet but soon will.
She is in the middle of a paint job. That should be finished in a little while. I hope you enjoyed this modification. These pump action shotguns are on sale for $25 at Bass pro shops as of Dec 8th. (I should be getting payed for plugs like that)
