Hi mitecarms, new to this site but I have followed for about 4 weeks or so. YOU have the talent. I would like to have copies of ANy plans/schematics U have. I have I think 4 of the pictures you posted a couple weeks ago. But for some reason all of are disappearing from here.
There are a couple "home-brew" designs I have tried with relatively good success, like the one contained in plexi-glass using brass tubing. I have it working bu not well as a 'feed' for bb's and air source are 2 components that are not quite efficient. Workin on that now and I will share em when it's worthy. I like your design/work.....nice. I have the 2 PB guns U used + another. Would it be out of line to ask you to send along pics/list/drawing of what you are using, have used to complete the parts/body and the bb feed etc. ? Just whatever your okay with??? e-mail? Don't worry I wouldn't hit ya with 20 questions.I'm very adept machining about anything. If so THANK YOU. If not I und. Either way....awesome job man! BM | ||||

Thanks Blurted,
If everything works well I'll be producing a few hand-made copies, later a cnc run if demand is high. The prototype is still being built and tweaked, so far it shoots through 450 pages of a phone book (I know, chronograph is the next on my list) and puts pellets through the same hole in my short indoor range. I'm also working on a high-cap pellet drum magazine as the helical is too fussy about pellet lengths. Hopefully it'll feed a variety of lead pellets without crushing them, as they won't be stacked as in regular column mags. My site is due for an update. | ||||

Thanks in advance for that. So far I've made a 33rd single column .22 mag, cast from zinc alloy. I'm going to try milling in future to get a better finish and greater accuracy. I've planned a true double column (not staggered) mag but haven't got around to testing it. It's also for pellets. I've made a helical mag as well, to test out the idea. I've concluded that for my application (i.e pellets), I'll need to make it larger in diameter to feed smoother. It's similar to the calico machine pistol magazines, but the rotor has axial grooves (not helical) and the projectiles aren't stacked radially (single layer). When I get the time I might try the helical mag idea for BB's, as they would feed easier due to the shallower helix and their easy-rolling nature. The only problem is how to get the last few rounds up the feed chute without some kind of follower - something I won't really mind when the magazine is designed to hold 200+ rds.

I will post either a picture of how I did it or a detailed drawing. I like photos myself, but it can be hard to tell at times due to the part(s) being so small. Keep your eyes open and I will let you know possibly later today; it is pretty easy to do. The mod 98 assembly is like a real rifle assembly, like most mechanical PB markers are, just a little easier to manipulate.
What type of magazine did you come up with, and how many rounds does it hold? I am still trying to come up with that "perfect" mag. | ||||

I look forward to hearing about your BB machine gun progress, it sounds like you're getting some good results. I agree that the venturi type guns are simple, but waste gas and aren't very accurate or powerful. I've built a simple blowback airsoft gun that runs on CO2, and am working on other guns as well. I've spent over a year testing and perfecting a design for an automatic air-rifle, and it's starting to come together (take a look at www.geocities.com/impactstoole/)
I'm interested in how yo converted the Tipman mod 98 trigger group to select fire. I haven't seen the internals myself, but am considering buying a second hand mod 98 to fiddle with. Is it simply a matter of disabling the trigger disconnect? | ||||

Your local hardware store should sell steel tubing which would fit nicely in the inside of the gun barrel, just make sure the OD diameter is a good match to your barrels ID. As far as a paintball gun goes; there are many, many brands and types out there to chose from. You can look around for schematics on the web by Google and typing in things like"painball gun schematics"-this is what I did. Look at the picture here in the forum and you will see the guts of a Brass Eagle brand (stingray model) paintball gun. This is perfect for my design since all the compenets are contained ; some guns are not like this. I purchased seven of the paintball guns for 20 dollars from a friend, five worked and two needed the O-rings replaced (very lucky). If you do use a paintball power system your gun will be very powerful.

I have not gotten that far...Ijust know I would like to shoot BBs and not plastic pellets...one of the tanks used in the nightstalker fits in my buttstock with no problem...I read that tippman has come out with a propane powered paintball gun that gets 15,000 shots before a refill...sounds too good to be true...i thought I would buy one of those and then go about figuring out how to fit it into the BAR.....I can tell you this...My BAR barrel is perfect for puting another BB barrel inside ....The reciever is plenty big enough to hide any paintball gun or Bb air set up...The magazine should easily be converted....I know I am not much help but a guys gota start somewhere...I also have a British Bren gun with a top loading magazine that would allow a simple gravity feed BB delivery...Bob

If the butt stock is large enough I would suggest going with a Co2 tank hidden inside of it, unless you want to run a hose off of the gun to the tank. Some guys on here are using HPA (high pressure air) with the coffer dam set-up. I really don't care much for this type of set-up/design due to the low velocity and unsparing use of pressure source. Sure they create a BB machine gun, but they tend to look too much like plumbing contraptions gone bad (please take kindly folks). I intend to create a gun that looks convincing as well as a performer. Your gun idea is a good idea with a great platform to base off of; what do you plan on using as a source of propelling the BB's i.e. coffer dam, recoil system? In case you are unsure, the coffer dam system is a syphon system that sweeps BB's up the same way a sand blaster, or a bottom feed air brush system works.

Hello, I just joined the bb forum today and your post was the first I have read....I am trying to build a full auto BB Gun using a 1918A2 BAR, Browning Automatic Rifle, as the basic weapon....I have every part to the gun except the reciever and some smaller rear site parts... I am having a steel reciever made up at our local machine shop and they are going to cut it out leaving me the barrel threads for the original barrel which is large enough to get a bb barrel inside....other then the gas tube machined area and the barrel the rest of the reciever will be pretty much cut out to leave plenty of room for any type of bb gun set up...I would like to use the longest lasting air/gas supply hidden in the butt stock as there is plenty of room...open to any suggestions...I also have a 50 and 30 cal Browning dummy guns I would like to do the same thing to.....any help appreciated ....I was originally going to make this a simfire gun but BBs are something I have always wanted to do with the BAR I wanna be able to mow down that row of bottles....not just make noise...any help appreciated thanks bob

Here are some pictures of the parts that I am using for my "home brew" BB machine gun.
- Brass Eagle stingray paintball gun internals - Tipman Model 98 trigger group converted to select fire (semi-full) - Winchester air rifle barrel assembly re-breached for bottom feed system    [ Too Many Images In Post; Maximum 3 ] | ||||

I am constructing a fully automatic BB gun from the guts (Co2 engine) of a Brass Eagle Stingray paintball marker (I have six of them!) aluminum sheeting, Winchester BB gun barrel assembly, and other parts. The gun will function on Co2 via tank and/or a remote line set-up. If the site will allow picture posting w/out hassle I will post the parts and progress of the project. It seems people are using the cofferdam (Venturi) principle when constructing BB machine guns; it is cost effective, but waste the gas source and doesn't propel objects that far. I have tested my set-up with a chrono and I am getting 830fps +/- 15fps results, and it is not using the gas source unsparingly. Of course the internals are from a paintball marker designed to propel a much heavier object(s) which should get/create outstanding results-I was aiming for this.
