M870 airsoft pump shotgun conversion

Messed around today...........some preliminary results with an airsoft pump shotgun converted to cap-firing.  Not there yet, probably goes on the shelf now for another rainy day to pick back up and work on it later......

Video - sorry for the ugly mug in there - didn't realize I was in the frame that much until it was too late!  Orange marking on the barrel    US rules with airsoft........


Here's a freeze frame photo of the flash:

Crickets!

Joke aside: Well done converting; looks great.

Well done on converting airsoft to modelgun, no easy task normally and yet again great muzzle flash

Great video! And this is an impressive conversion too!

BTW "ugly mug"? It must be my media player as I can only see a hell of a handsome guy here.

Could be nice if you can make a tutorial

Yes i fully agree

can the internal mechnism be used ?
how did you build in the detonator pin ?

Very VERY interesting project

Would love a tutorial as well! Did you use the PPS as the base, or another model?

Hi all.
The base airsoft shotgun is the PPS model. I found it online at a sale price of $178US delivered, and that included a bonus crappy spring pump airsoft shotty. For the price, I thought I'd give it a try!

I haven't had time to get back to this project, but hope to once it turns cold here. I still have some experimenting to do, but it does seem very promising initially.

I will post up when I get back to it and let everyone know how I get along. Whether it is a failure or success, I'll let you all know.

I know if it does workout ok, I will be very happy!!!

Well, I just couldn't wait...............so I put off things that I SHOULD HAVE BEEN DOING, and picked up the 870 again.

I'm not 100% satisfied with it yet, but it cycles and fires great.  I've probably cycled and/or fired it 100 times.  Occasionally I get a slam-fire - that's keeping it from 100% right now.  Probably the addition of another o-ring in the cart and it'll be good.

So - here's a couple carts in action:


As far as a tutorial - I'll get up some info later for anyone interested in trying this out.  

Get that tutorial up - would love to see how you did this!'

Of course we're interested! Are those just basic MGC shotty carts?

Great video! An airsoft/pfc hybrid. The forum founders/managers will need to include a new category! Thank you for sharing, Chris

Updated my 870 airsoft conversion - working great!  Here's a vid with just 5 caps per cart instead of 7.


I do plan to do a tutorial sometime soon - sorry for the delay.

Must. Have. Tutorial.

You've got that thing working smooth as heck, man!

It's great to see it in action  

Excellent project.

Yes a tutorial please !!!

Brilliant job, looks excellent i want it give it to me

Excellent!

Very impressing job. Thank you very much for the update!

Plain and simple a brilliant idea

I confident it's not that simple - but really curious on how it's done

i noticed some muzzle flash leaking from the chamber but other than that, thats pretty awesome

Great job!
Idea might have been simple yet execution is key here, your videos prove it :-)
