If you may recall a while ago, I posted a mod for the LSB that was a FAILBOAT. I ended up destroying the integrity of the blaster, and it now hangs on my lonely wall of shame.
However, I recently acquired an Lbb with no monetary loss of my own ( Thanks BlackFox ), and finally decided what to do with said blaster. So, with out further ado:

Pinky and the Brain

Supplies Needed:

HOTGLUE
Amazing Plumbers Goop
E tape
1/2 in. SCH 40 PVC
9/16ths brass
19/32nds Brass
3 1/2 in. Sch40 Pvc Couplings
Ace#49 spring

Tools Needed:

DREMEL
Hotglue Gun
Band saw
Screw drivers


This writeup will come in two parts. First, the NF mods, then the LBB Mods.

Act 1: Pinky

First take your NF, open it up and remove all the useless AR drivel. Then take the plunger rod out, etape and lube the plunger head, and then swap out the wimpy stock spring for the Ace #49 one. I had some spring shenanigans after this picture, so these aren't the actual springs I used. But, you get the picture.

Like so:

Then take your band saw ( or dremel, if you prefer to be messy ), and cut off the handle, ammo holders and cocking handle of the NF, then with your dremel, widen the barrel hole on the front enough to accommodate a coupler.
Posted Image
For some reason, I must have huge couplers where I live, because I couldn't get it to fit in the plunger tube at all. So I had to grind out the outer edge of the coupler to fit over the plunger tube. Once it fits properly, Goop away!
Finished NF:

Act 2: The Brain

Take your Lbb, open it up and cut off the orange stock barrel.
Posted Image
Then take 2 couplers, a length of 1/2 in. pvc, and a length of 19/32nds Brass. You have to make the the couplers and PVC long enough to be just beneath the barrel hole of the Lbb. If you've got it figured out, make sure to hotglue the couplers and the PVC together. If it leaves you a little confused, just wait. There's a picture of this assembly in a bit.

There!

Then take your band saw, and cut off the entire trigger gaurd.

Finished Lbb:

Act 3: The joining
Posted Image
If you cut off the trigger guard of the Lbb, there should be a rectangle shaped box on the underside of the Lbb near the front just begging for something to be put there. And if you put it there, and cut off the cocking handle, the plunger rod should just fit right before your hand.
After its been secured there, Hotglue the crap out of it.

With an 8in. brass barrel for the lbb, and a 3in. brass barrel for the NF, this is what turned up:

Nf: 58ft, 61ft

Lbb: 91ft, 96ft

I didn't actually do the 19/32nds nesting part, because my crappy adhesive skills, but I'm pretty sure that would put the Lbb ranges into the 100s region. I also found that you can fire the NF in two ways. 1) Angle it up a tidge ala M203 style. 2) flip the entire blaster upside down, and viola! you have a NF-like rifle.

Questions, Comments, and Flames are welcome here in mai threadz.

Not really, I hold on to the Lbb with my right hand, angle the blaster up, and pull down with my left hand.

It looks like a tight squeeze when you prime the NF. Can you still comfortably fire the LBB?

I have really tiny hands, so yeah. But if you have bigger hands i'm pretty sure you cut down the NF plunger rod even more.

Looks great! Though I do suggest you re-attach the NF shell so that the left and right shells of both guns are only connected to the left or right shell of the other gun. This way, when you want to open the gun again, you can do it without having to rip off the NF.

Further thought: if you cut down the NF even more, it may be possible to link the triggers. That could be counter-productive though, since you would have to leave the NF unprimed. Kudos, though - this looks practical.

Might have been better if you stuck the NF to the top of the blaster, and used the LBB as a hip-fired multiple dart spread blaster. Although most blasters have lower integrations (mostly springers, that are more effective shooting from the shoulder, but an NF on top of the LBB would be a close quarters nightmare.

Doing this as I speak. I have no idea when I got it...my DAD got it some 15 years ago, but that doesn't matter. Anyways, it keeps jerking around all over the place. I try to hold it with a rag...It doesn't look like...much.

Cheezpizza001: Funny you should say that, Right after I finished everything, I came up and showed it to my brother and he suggested I put 3 more NFs on every side of the gun. lol. I hear what your saying about it being easier to open, but it would be really harder to put it anywhere else, because of the rounded surfaces of the blaster. This way was just the easiest way that jumped out at me.

Daniel Beaver: I thought about liking the triggers with a keyring right by the Lbb trigger, but I was lazy, so I decided not to.

Tantumbull: Yeah, I tried pulling on it really hard, and it won't come off.

The idea that I had when I started making this blaster was to a have a main long range gun, and then a back-up for rushing buttheads.

I like it. The NF integration is rather interesting. Also I have a question, because of the coupler extension does that lower ranges because of dead space, or does that not matter for an air-gun? Great work overall, but one thing what kind weights and foam are you using to get your ranges?

Possibly the highest compliment that could be paid on these boards :P

Yes, very practical and I would say effective. Iíd also like to throw in cost-friendly and not terribly difficult to replicate.

Just cuz it does not have tremendous flair does not mean you canít pull an 8.5/10. Nice work.

I don't really know if it affects it or not. I tried this same mod on a LSB a while ago ( As mentioned ) and I didn't see much of a range decrease in it when I changed back to a normal coupler system.

I'm using Hereticorps Black Mile-high foam with 2 BBs in each dart as weights.

I think it's just the hot glue, which is pretty unbelievable(sp) considering the strength of the spring.

Very functional mod I just have a few questions.

Are the couplers glued to the PVC?

Also if not when you pull the speedloader out does the main coupler come out?

Once again very nice functional mod.

Good mod, it is really cleanly integrated. If you gave it a new paint job it would look really good.

I assume you mean in the coupler extension, and yes they are glued together. Thank you for asking me about that, I forgot to mention it in the write-up.
