More photos to come, had to use MS Paint to "re-size". Works very well for that.
I'd like to share some specs:

Made from grip of a PB Gun,
Handmade mag./clip holds 45 rounds
.177 Cal. BB ammo
900 - 1100 FPS
Cyclic rate @ 40 RPS +
HPA and/or CO2 Tank powered
BB feed Mech of billet alum. (Secret= pending designs)
Blow-Back action.


Project of mine for a couple years, having other design Protos.
Like to see/build/mess with BB Sub-MachineGuns as a hobby.
Have a working & solid knowledge of history of pneumatic BB full-autos (Vortex & Venturi Pump designs).
Currently experimenting with my own calibers of lead rounds, but range of .22, .25 & .32 cals. NOT Pellet, similar bullet design,
and spring-fed mag. clips that will function like a true mag. feeding into breech/barrel. This is a powerful full auto blow-bak design
I would like to get into a machine-shop and re-build into a more militarized small arms look and feel.

Please bare with me.....MORE to come. I'm only ONE guy workin out of my back room shop of small tools.

Thank you for viewing/reading, OPEN to questions, advice & positive feedback or opinions.
E-mail me with those if you have some interests. brandon.marshall41@gmail.com.

All the best,
Brandon M.

Here's some other first Protos of full-auto (strictly experimental) BB SMGs'.
More to post just to share a few of the recent projects.

Hope these share some extra concepts regarding fully automatic blow-back action .177 cal. BB machineguns.
More to come. I realize not everyone is interested in Full-Auto Airguns. There aren't many in existance that don't
require electronic valves, but these are compressed air operated ONLY, hand made without good equip./tools.

Hopefully I can obtain some help creating much better airguns, just as or more powerful than these and with
a more "beefy" look like that of an UZI or MP5 SMGs'. Not everyone can afford a machine shop. Tho' I contribute to
new power, new ideas and new airgun potential.

Thank you for viewing, sharing & posting. I'm new to this site so I hope someone will share some insight.

Videos coming, TY for all who share views. Trying to slow down cyclic rate, these are so fast. Emptying clips in a second or less.
Not havin a lathe can be a real bummer when ya have good designs, can't make changes. Need longer rear bolt/drive spring to slow em down a bit. I'll post some brief clips soon. Anyonw ith machining exp. I'd really appreciate some advice/tips. Thanks guys.

I have no machining advice but I will mention that a rotary style mag would look cool on that last gun!

Rotary mag I am working on in fact, instead of a belt feed sys.,

thats a lot of imagination , love to see a vid.

Link to vid, (today), indoor short-ranged result. Next time I'll hold the trigger instaed of burst firing manually, better result for full-auto.

Later more full-auto tests with different home-made airgun(Vids). Sorry for the lack of video editing expertise and/or out-door range with better targets. Neigbors panic when I'm test-firing stuff.angry with "no" sign

Hi Brandon,

Thanks for posting the video. It's impressive how fast that gun shoots! You are doing a nice job.
