Did you even read the responses on that thread? Keef and others tried to do this mod. None of theirs worked. Cole had a certain Double Shot that worked perfectly for the mod. I think you may have just screwed your double shot.

But Cole said he had done it to 3 doubleshots not just one.

Well I tried pulling the pvc/cpvc insert thingy out more and gluing it in but it still did the same thing. How do I improve the seal and what is a good barrel length?

Probably 4 or 5 inches should be fine for the DS. To improve the seal I would slowly close the break action part, and try to see if the foam plates (not sure what to call them), touch the CPVC. Try replacing it with a rubber washer, or something like that.

My barrels are 3 inches long so I will try fixing the seal.

So I tried to do General Cole's no shells doubleshot mod but when I load the darts and shoot nothing comes out of the barrel then when I prime it and shoot again they go about 7 feet. What is wrong and how do I fix it?

I don't think that is the problem because I have had my plungerhead stop when I put my hand over the front of the barrel. I will get pictures up tomarrow I am to tired to do that right now.

Do you mean stop like no movement at all or a slow release of air? Did you replace or add a spring, because if the spring was weak enough that you could hold back the air by plugging your finger down the barrel, the ranges you were getting were realistic unless you have stumbled across the perfect seal (which I doubt) My recommendation would be to put a larger spring or add one to the bbb spring to get a little more *umphf* out of the gun.

Like I have had it stop stop and then when I release my hand I can hear it slam forward. I am going to add another spring as soon as I can find one I am just looking for the right one to add. Also I do mot think it is a spring problem because I put it in my longshot and got 90 flat.

Did you do a plunger head replacement? The unfortunate thing with BBB's is that they can have an amazing stock seal, or a bad one.
However, the seal may not be the problem. My BBB (red) had an amazing stock seal; it vacuum loaded half of the time. I did the same as you; filled in dead space with hot glue, CPVC coupler, and an 8 inch barrel. However, I only got around 60 fee as well. The problem for me was my darts. Not sure what it was, I was using 3/0 fishing weighted darts, and my foam was a bit loose, but not that much. Anyway, try some different fits of foam, different weights, etc. Barrel length doesn't usually affect range more than 15 feet or so, at least I've found.

I must have gotten am amazing stock seal because all I did to the plunger head was to fill the little ring it with hot glue. I will get pictures up I a little bit. Also I don't think my darts are the problem because I modded a friends BBB exactly the same as mine but with a PJ and a 4.5 inch barrel and he was getting 80-85 flat. Could it be that he is alot taller than me like 1 2/2 feet taller?

I don't think that is the problem because I have had my plungerhead stop when I put my hand over the front of the barrel. I will get pictures up tomarrow I am to tired to do that right now.

I did read that but I wanted to get more than one persons opinion with what they used and had success with. I would appreciate a quick response because I need this for the next war I am going to in 5 days.

OK so I modded my BBB nothing special, reinforcements, front sight taken off, couplered and all that jazz. I have foam that slides into cpvc nicely and may, on ocassion need to be twisted in. Now I have read of people getting 90ft. flat with a dead-space and barrel replacements. I am using a 4.5" scrap of cpvc yet I am only getting 60-65 feet flat. My question is what length of barrel are you guys for your BBB's?

I am free but it would have to be close to my house because I don't have a car.

I am on vacation till the 10th but if its at Cherokee I might be able to make it.

Have you checked out the park yet?

Use florescent paint if you can. It seems to be easier to see in the grass.

What is the address of Cherokee park? I may drive over and take a look. I'm also looking into some parks just south of lake Harriet in Minneapolis.

The adress is 700 Cherokee Heights Blvd.
Saint Paul, MN 55107.

There is a very good location called Cherokee park In St. Paul. I can get pics if its a possibility.

I will be doing contracts on longshots and BBB's or almost anything else. Just PM me if you want me to.

I really like this mod, I just have one question: doesn't the slide get in the way of the dart tooth?

I don't need the dart tooth because I did a Brass Breach.

Why thank you. The internals were not in the gun because the epoxy for my brass breach was drying. It doesn't work now though because I snapped a piece in the plunger tube but am getting one from Modsquad As soon as he responds to my PM's!

Check out my trading thread here

Yes it shoots 100' flat but at that point I didn't have any other internals in it. I brass breached it and improved its seal. ROF is very good actually.

I will change that later I am to tired to do it right now. Are the pictures working though?

I wanted a way to make a fore grip for my longshot that was easy to do, cheap, and looked somewhat aesthetically pleasing.
I think I have found a way to do this. It happened completely by accident. I was trying to figure out a new mod fore my longshot, something that has never been done before. So as I am looking at my longshot internals I picked up the boltsled and something dropped off my workbench and my brothers dog spooked and scratched the back of my leg. I dropped the bolt sled and went to go "tend my wounds" and when I came back and looked at my gun the bolt sled had landed flipped of its normal position. Then i said "I got it!" and this is what I came up with.

Tools:
Dremel
File
Drill

Supplies:
2 inch PVC
4 small bolts
4 nuts to go on the bolts

Step 1:
Remove the Bi-pod and cut your shell to look like this,
http://s508.photobuc...nt=IMG_4850.jpg[/img]

Note: the hole on the bottom of the shell needs to be 1 1/4 " wide

Next cut the bolt sled shorter so it should look like this,You also have to shave the part where the priming handle goes through that area should be flat. Also those two little black wheels need two be taken out of the bolt sled
http://s508.photobuc...nt=IMG_4859.jpg[/img]

Now set the bolt sled aside and lets start prepping the shell.

After

Note: You need to remove all 3 of the little "walls"


Next, put your bolt sled in like so. It should be able to slide back and forth pretty easily.

http://s508.photobuc...nt=IMG_4747.jpg[/img]

Next slide the bolt sled all the way back and take your 2" PVC and cut it to 4" long
http://s508.photobuc...nt=IMG_4858.jpg[/img]

Drill two holes in the bolt sled like so,
http://s508.photobuc...nt=IMG_4859.jpg[/img]

Next place the PVC like shown in the picture.

http://s508.photobuc...nt=IMG_4868.jpg[/img]\

Those are my knees by the way however different they might look they are knees.

Mark the PVC with a sharpie like shown,

http://s508.photobuc...nt=IMG_4863.jpg[/img]

Next drill out the two holes in the PVC you just marked

http://s508.photobuc...nt=IMG_4864.jpg[/img]

Assemble the bolt sled and PVC like shown

http://s508.photobuc...nt=IMG_4865.jpg[/img]

http://s508.photobuc...nt=IMG_4866.jpg[/img]

Place in your gun and reassemble the gun. It should look something like so,

And slide easily

Questions? Comments? Flames? I am not sure how to post pics directly on the post so if you know how please tell me how.

I know that the breech cut is 3 inches or 3 1/2 inches.

This topic is over a year old. Read the code of conduct. There also was another person who posted on a year old topic and yet you did it again, unbelievable. Plus, you added nothing significant to this anyways.

Got it but i was thinking of starting from scratch not using the piece from the magstrike.

I understood it but I wanted to make sure i got it right. I am designing one in Paint right now.

Ok thanks , but do you know how i could make one?

So I am making a semi-automatic homemade based off of the magstrike but i don't quite understand how the big white piece at the top of the picture works. Can anyone help me?
http://nerfhaven.com...trike internals

OK i am so with my magstrike when i pump it and let go of the pump handle it pops out and so the tank can fill. Can anyone help me? Getting video up right now.

Your check valve is broken. Either make a new one or buy a new pump.

What is the check valve? This is the first time i have opened my magstrike because it wasn't working.

Just buy a new pump then if you don't know what I am talking about.

Could i just use a ball pump to replace it? Nevermind guys I should have know it was the check valve. I blanked on what it was untill i looked one up the i was like "Duh!"

That would be possible.

Ok thanks for the help.

I am excited for this to come out. I will be getting one for sure! I think the front attachment looks cool.
