Well I certainly haven't posted around these parts in a long time. So it goes.

I'm rather out of the scene on what's the new and the wonderful in this fine land.

My friends and I have begun an assassin type game. The weaponry consists of nerf, rubber band guns, so on. I've decided I must quickly take over the arms race.

I remember a PAC3 esque gun somewhere around these parts. But you guys can hopefully educate me on what I should be doing.

Basically, I need a 100+ ft loser rifle. One shot is all I should need, though a quick second can never hurt. I need something relatively easy to build, price isn't especially an issue. Hopefully I can shop one day, piece this thing together the next, and on day 3 be ready to make killings.

I've read through the first few pages of the boards, but at this point with being away from homemades this long, it's daunting. Somebody fill me in with a quick summary and tell me what I should be doing.

I’m assuming you ruled out trying to assemble bolt losers FAR. Other than that the options for what you want haven’t changed drastically. If cash isn’t an option grab a Titan. Seems like just what you want, just without the hard work of a homemade.

Testing for ranges done at 23 pumps, little to no wind, measured with a walking tape measure:
172'
174'
195'
AVG: 180'

I plan to do testing at lower pumps, but maybe in a few days.

Three days isn’t really that much time to build a homemade, but if you in a hurry and don’t like the titan idea then I’m not sure what to do.

You're shit out of luck. No such NERF loser rifle exists.

Now if you're looking for a long range blaster, Airtech2000s can get 90' easily with a single barrel mod. Mod the turret for 4 shots of 80'. Titans get crazy ranges but you probably wont want to kill anyone, so I would suggest against it. The Lanard Blast Bazooka should still be in some stores, this is another 80-90' range blaster.

[Devious]

Titan, hands down the best long range gun when modded beside the SM5K

you put a dart launching barrel on it for micro/mega stefans, and you have the most lethal gun ever

DO NOT SHOOT AT SOMEONES HEAD UNLESS YOU REALLY WANT TO KILL THEM!

[Jin Kazama]

A brass barrelled AT2K can get 110+ ft.
As fore-mentioned the titan gets massive range.
A well done Blast Bazooka will get close to a 100 ft.
A well done maxshot will get 100+ ft.

Those are the easiest to get loser esque guns available.

To actually answer your question, I'd suggest looking at this writeup and working hard on making some super accurate darts. That gun would probably, in retrospect, be better suited to mega (5/8") stefans than micro stefans because they fly straighter and there's plenty of power. If going with mega stefans you would obviously replace the brass/SCH80 barrel with a SCH40 barrel. Makes the construction even simpler.

The other idea I'd considered was making 6" long micro 'rockets' for that gun with a short, heavy micro stefan impaled on a thin straw with small fins at the end. Should be super-accurate and again, the gun is more than powerful enough to handle it.

About what are the ranges and airtank volume on that rifle Cx? I'm making an air powered "loser rifle" and need ideas for the airtank size.

About what are the ranges and airtank volume on that rifle Cx? I'm making an air powered "loser rifle" and need ideas for the airtank size.

The airtank volume can be estimated from the parts list, specifically:

1.5" x 9" SCH40 PVC
1.5" PVC Endcap
1.5" PVC 45 Degree Bend

The range is unclear because I've never given it a proper range test. When I constructed a (roughly 60' long) testing area in my back yard the darts were still going fast enough when they got to the paper target that I needed to hang a blanket behind as a slow-acceleration backstop. At 60' if the darts hit my wood fence the FBR would flutter to the ground while the hot glue and weight ricochetted off in two different directions at crazy velocities. I actually got pegged one time by a piece of hot glue that made the 60' round trip.

My darts were also extremely inaccurate at these velocities so it's clear that the limit to this gun's useful range lies in dart construction rather than the gun itself.

I had been wondering about how progress had been with that.

[AirApache]

Looking over the BAMF and considering doing a variable of it.

What method did you use to do the porting at the end of the brass? What advantage does it give you? Is it just to avoid excess air pushing the dart out of control or something?

[JiF]

The BAMF sounds like the best idea I've heard of as of yet. I'm thinking I won't do a bleed valve, I'll rig the solenoid up electrically. I remember back in the day having a lot of trouble getting ahold of FBR. Has it become more widely available? Lowe's? Home Depot?

The member numbers here have gotten hella high.

...says member number 12. Yeah, there are a lot of folks registered.

FBR can be had at most Home Despots and Lowes stores. You can buy online at loghelp.com and other similar sites.

Heh. Vacc told me about this place before earth found out. He still around?

[Arcanis]

Okay, I just came back from a sad excuse of a school "dance". I'm tired and hungry. So excuse anything... "bad".

First of all, I drew up a quick diagram for those that don't have CAD embedded in thier medula oblingata, which wouldn't make sense anyways because the medula controls motor movements...

Yes, it's quick. Yes, it was drawn badly. Yes, it was drawn by someone tired, hungry, and grouchy.

Oh and one thing I forgot to add was a fill valve. Yes, a fill valve; you'll need to make a hole somewhere (prefferably the bottom of the stock) for a tire stem valve.

Anyways, glue it up after trying to understand the modified Zero valve (Can someone give a better explanation?), fill up the tire valve, and fire that sucker at 70 PSI.

Anything too much more than 70 will be dangerous.

Yes, I have to agree the BAMF works very well, and is extreemly powerful. Cxwq: Do you know the range of that thing at like 30 PSI? I used to have one but I scrapped it for parts to my SATR which im working on right now, it will be a true semi-automatic rifle but im getting off topic here.

[JiF]

In process of building a BAMF. I've got most of it done, save for a few parts. My hardware store didn't have a 24'' piece of SCH80 riser. So I got two 12" and the appropriate coupler. I'm having issues with brass tubing. It doesn't seem to exist around here, so I'm going copper I suppose. All of the sizes of actual tubing seem to fit oddly insice of the SCH80, save one. The one is actually a copper fitting that is 12" long and fits over 1/2" copper pipe. That sits in mighty well, and a micro slides down such perfectly. The only problem is that it's only 12" segments. Should I stick with a 12" barrel or get two of them and join them like you did with the brass pieces in your writeup? Also, what is to prevent the inner barrel from flying out along with the dart? You dont mention any method of retention in the plans.

[cxwq]

Friction.

The brass is wrapped in electrical tape which fits tightly in the PVC.

I'd go with 2 12" pieces, bevel the inner edges where they meet so it doesn't tear the darts.

[VACC]

Heh. Vacc told me about this place before earth found out. He still around?

That'll do it.

Question: What diameter are the tire valves you used? Mine were apparantly .453 diameter, which is far from the truth. They micrometered at about .590. I'm ordering a new drill bit.
