Step2: Sand out the Inside Of the orange part out until a PVC coupler fits In It.

Step 3: Epoxy that coupler In the orange part. Get It as strait as possible.(Sorry no picture)
Step 4: Cut one side of a cpvc coupler up to the ridge in the middle.

Posted Image

Step 5: Put a cpvc pipe through this brown piece. Put a coupler on the end pull It against the brown piece and put hot glue aroung It.

Step 6: get a 1' piece of cpvc put E-tape around an Inch or so away from one end and put somemore on the other end and slide some Thinwall pvc over It.

Nice! I've been wanting to get one of these for a while, and this is a mod I will consider doing.

Ranges would be nice.

Oops, I knew there was something I was forgetting. It gets high fifties low sixties. I thought that was pretty good since I didn't do any seal or spring Improvements.

There's not much you have to do to the current seal, and a spring as simple as a longshot spring will pump your cannon up to the 80s or 90s

Good stuff though, I really like the coupler ball attachment, I didn't even think of that with mine haha

Cool mod. I did pretty much the same thing to mine, except I put in one and a half NF springs. Adding the springs makes it go 100'+, depending on the dart for it to go over 100'. The only thing you will have to do if you add the NF springs is reinforce everything and add another spring for the catch.

Does any one know a ACE spring # that's 7-8'' long and not unusable?

I would recommend you do something like dayko did. Get two ACE 49 springs and cut one of them down so that they both are long enough to fit when they are stacked on top of each other. If not that, I would recommend LS or 3b springs. Hell, Carrtoon had both in his pump shotgun and it shot as far as my pump plugged big blast (roughly). I've checked ACE a number of times and I am pretty sure they don't have a spring like the one you described.

Sorry about the semi-necro, but dayko do you mean two stock NF springs? Or were you just being mega technical about the #9173 ACE #49 difference? Because I really want one of these and if I did get one the only thing I was worried about is what spring to put in it.

Okay, I usually leave ppl that necro alone, but the recent wave of them has been annoying me because I keep thinking there's a new mod for a gun, so here goes.

Read the CoC, if you have a question, don't necro a topic, PM the person instead unless you have something major to add to the topic.

Okay, wow, that felt good. I'll still not make a habit of it though.

I didn't think that 6 days was considered a necro? I always thought the general rule was 2 weeks or older, this six day rule must have slipped past me.

Anyways, I really like how you kept the ball gun attachment. I love when original ammo types are able to be used with the finished product, it just makes the mod that much more awesome.

I mean the original NF springs. FA_24 said that the Whiptail spring was like a NF one but longer and 2/3 bigger. So I though I would just use one and a half NF springs. Also if you want a little more power in your Pump Shotgun put the spring from the orange thing that pushed the balls forward. It adds about 2-3' increases.

Now I feel stupid... that's what I get for only skimming the first few posts.

Renegademilitia15 I'm sorry for snapping at you.

Dayko: Thanks, I have one stock NF spring but how big is the plunger rod? Would a stock ttg spring fit around it?

Bullet Dragon: Its ok bullet. I forgive you.
