First and foremost, I must say that for 80%+ of the stuff in this pistol, credit goes to Boltsniper. Some of his ideas have went into this, and this pistol serves as a proof-of-concept of some of those ideas. Oh, and check out his BS-9 on www.boltsniper.com, which is his newest pistol, and was the first to incorporate both ideas presented here (he just didn't put in the shortened plunger, but he made it).

First off, I'd like to say that this gun is smaller than a NF. I'll get some comparison pictures up as soon as I finish up sanding a few things here and there.

Posted Image

When primed, the gun is no longer than it is when it is not primed. Basically, you pull back the slide, which pulls back the bolt, which pushes on the front of the plunger head. As it travels back, the beveled back-end of the plunger enters the catch, pushes the catch pin down, and locks on the catch face. Simple, ingenius, effective, and all Boltsniper.

Posted Image

Secondly, the reason why there is so little air loss (why the clip results in less air loss, even without the use of shells).

Posted Image

All it is is two pieces of brass, with the inner piece having a hole in it. When the bolt is pulled back, it exposes the hole and allows the dart in. The bolt then moves forward and seals the hole. It's basically an Unknown Breech, but with brass; and the thin-ness of brass allows it to seal a dart without the bolt jamming on the next dart. Also, the fit with which two pieces of brass slide together allows for a seal which does not require any o-rings. Below is a picture of the inner brass inside the pvc; you can see the space between the brass and pvc which is where the outer brass slides.

So there you have it; the smaller-than-a-NF clip-fed pistol that gets ranges of over 60'. I'm not sure exactly what I was on, but a friend of mine asked me that I name at least one of my creations after her, hence I'll have to name it the MEG. No acronym really, like the NEAR, but short for Megan. Sorry Brammer, a promise is a promise, and I have to keep the promises I make.

Anyways, once again, almost all of the credit here goes to Boltsniper, for enlightening me with his ideas.

Oh, and I have to say; You guys should try using this bolt system. I will NEVER again go back to what I had. This has minimal air loss, and minimal dead space. It's like a dream come true, sans shells.

Ranges of 60-70' flat. At least when the two times when I went out and measured them they were 60-70'. I'll do another test in a few days and post again. Also, I'll try to get some videos of it firing out shortly. And lastly, I know it looks something like a Tec-9.

Awesome! You basically created the Holy Grail of sidearms. Nice job.

No, the BS-9 is the holy grail of sidearms. This is my imitation of the holy grail, made by an asian kid. Asian replica of american product. Sound familiar?

Pure Awesomness. 60-70' range with a gun that small... That thing's worthy of being a primary, let alone a sidearm.

Great Job Ompa and Boltsniper!

EDIT - Forgot to ask - How many darts fit in the clip?

As of now, around 5. However, I plan to re-make the clip and use a stronger wire, so I should be able to fit more darts in there.

Dude, that is so badass!

Didn't realize Bolt had finished the BS-9.
I'll have to go take a look see.

How the F*** do you cut brass like that!?!? I've had so many ideas thrown away because I couldn't figure it out!

Please don't say "with a saw" or something, because then my saws will feel weak...

But... thanks.

How long are the darts you're using? I try and keep darts the same size for all of my guns, but that's getting harder to do while keeping designs practical. Your design looks pretty practical, but how long are the darts?

I cut brass with my teeth. No, I use a dremel and a cutting wheel.

The darts are shorter, about an inch each.

Posted Image

Lastly, there's one quirk about firing that is demonstrated in the video; When I screwed the top and bottom together, there was a little bit of wiggle room. That means that whenever I try to pull the slide back, the top pulls back as well by a few millimeters. While it may not seem like much, it ends up messing with the catch pin. To counter this, I either have to a.) glue the top and bottom halves together using epoxy, or b.) use my hand to brace the top half while priming. I chose b. I may glue them together later on so I don't have to do that, but for now it only adds maybe a second or two on to priming.

Video Link

Actually that lastly was a lie, as I just remembered something. The reason why it is able to shoot somewhat close to NF ranges is that the volume of the plunger is actually somewhat similar; the use of a more powerful spring, and the larger plunger diameter being the explanations as to how the plunger volumes are similar.

I've been meaning to ask you tihs for awhile now, have you war tested any of your homemades yet? It would be cool to see how much a gun like this could change what you could do in a war. Have you thought about making this gun possible to dual wield?

What's that small downward facing ring of CVPC for? You can see it in the last picture of your first post, on the righthand side of the picture. What purpose does that serve?

Oh, almost forgot: very, very nice job. Pretty damn quick of you, I must say :P .

Just a spacer, really. I may use it as an attachment point for something later on, but nothing is planned as of now.

I haven't war-tested anything yet, but I expect to either late this year or next year, when I'll be living on the East Coast.

Ok just one or two more question I swear.
How long is the gun? How long is the plunger stroke?

So, you've built a clip-fed pistol, smaller than an NF, with ranges over 60'?

I don't think theres anything I can say that conveys how amazing this is. I think the biggest congratulations goes out to actually building this mofo from it's conceptual design. Take the most pride on that, because that's what we all lack most.

Ompa that is so friggin sick. Looks kinda like a Mauser which is also pretty sick. Good job as always.

But the thing that I like the most is that the priming handle and the breech opener and closer are all in one motion. That way you only have to cock and you're ready to go. I don't like it at all when I see a modification or homeade that requires you to do three or four different things in order to fire one shot.

Also how is this breech system and different then that of say the one on the near, so far, or some of your others?

The bolt covers the dart, instead of moving the dart forwards, resulting in less dead space. the LOP is around 2-2.5".

Again, the two main ideas that made this possible are Boltsniper's, not mine. If anyone deserves credit for these things, it's Bolt.

Great work, but have fun holstering that :blink: I always figured the first successful mag fed pistol for nerf would be mauser like.

Very Nice! I love the video of it functioning. Makes a very nice pop.

I built the trigger system for the BS-9 today so the only thing left is paint. I should be able to get it up in a few days.

Do you have a name for this gun? Like the Boltompa or something?

I think this may have already been asked...

EDIT - It has on the Boltsniper forum. Nevermind.

Hey ompa,

How stable is the clip? Does it fall out easily? If not, what kind of mechanism did you use to make sure it stays in place?

It's fairly stable, although you do bring up a good point. It's basically like jamming a piece of pvc into a coupler. It's reasonably stable, but not as good as a pin. I WILL get to that eventually, it's just a matter of drilling a hole in one of the couplers and then into one of the half-pvc pieces I have on the side of the clip.

Anyway, forgot to congratuate you ompa, for your awsome gun. Even though it is based on Boltsniper's design, making the gun is still an amazing feat.
