Fair enough. I guess we won't know what's actually in there until someone gets their hands on one of these.

Only if you intend to resell that information, as far as I know.

Yeah, I've been to that site before.
However, to build something as compact as what this guy has done, you'd almost certainly need to do "special machining" (whatever that means).

To give you a little history on the X177 itself, during my airgun experimentation, I set out to design something that ...

Yeah, I know they exist. Don't most electro-pneumatic guns function like the Drozd, though? The guy said he didn't like the Drozd because it's too loud.

I'm willing to bet it's probably nothing more than a well made magazine fed "cloud" BBMG with some sort of adjustable breech detent and valve flow that alters velocity and rate of fire respectively naahh I already concluded that it must be using a solenoid valve and a timing circuit

not sure if it ...

Yeah, I got the email update, too. It is rather interesting.

What kind of chrono are you using? You mentioned something about "needing an optical chronograph"...

The ID of 1/2" Sch. 40 PVC is slightly under 5/8", probably close to .615. So, yes, it would fit, albeit loosely.

.1" is quite a bit of slop, when you're talking about ammunition fit. That comes out to be .050 on each side, leading to blowby and power loss. If you really want to use that size, I ...

precise measuring ustensil

Rulers are for large measurments in inches and centimeters. Not hundreths of inches.

Besides, if you wanted to get a somewhat precise measurement, you could just go to Harbor Freight and get a $10 digital calliper. I have one. Frankly, it's a piece of crap, but it ...

So, basically, you want to hook up a homemade pneumatic cylinder to a lever?

Sounds terribly inefficient. Also, it has been done before, just not by anyone on this site (that I know of).

Why did you post about it if you weren't going to build it?

Actually, that's a really good idea...I may have to steal that for my next build.

Is that a computer fan guard?

That is simply incredible. I may have to acquire one...now.

More or less like Nerf PlusBow, but for paintballs and a feeder.


+Bows aren't at all semi-automatic...I think you're referring to the ABP5K , made by the same person.

If you have an air compressor, or even a bike pump, I would recommend a simple valve hooked up to a barrel and an air tank ...

I found it through Nerfhaven.com.

Quite a few people from there are members here (not surprisingly).
