Better known as the Baretta 92FS or the M-9 Military. This Full Auto Blow-Back Co2 Pistol  replicates the Bump and Jump , feel and weight,  of the "Real Deal"! At 50 ft. this gun groups amazingly well  for a BB Gun. With the cost of 9 mm ammo...this is the perfect solution for real time target practice!  Now, I rigged this gun for Bulk Co2 as I have for over 20+ guns. Shoot all day for pennies! BB's are cheap and recyclable....especially on Full-Auto!    Any questions...feel free to ask! It's all about sharing! dave

Yep! 

Nice setup, John! Can we get some pics of the hardware you used in the Mag? I use the 8.5 Carts to plumb to with 2000 psi Nylon tubing and comp fittings (Ace Hardware) and Ninja Fill Checks. Hey, whatever works! dave

I've posted about it someplace, and will have to find it.  It is not as economical as your set-up.  It uses an ebay cart with foster/checks.  The brass coupler was from Amazon and is meant for pressure washers.  It fit the mag without any mods to it.  I use a slide bleeder on the hose, tethered to a hpa bottle.  I can swap out the mag for reloading with minimal air loss. 

PS: it was buried in: https://www.airgunnation.com/topic/crosman-dpms-sbr-build/

Thanks for the Pics, John! BTW, That's a way cool site!   I can see exactly what you did now. Nice job! I did have the luxury of having and extra 50 extra ft of 1/8" 2000 PSI nylon tubing left over from doing the hydraulic brakes on my chops. The smaller 8.5 gr powerlets had to be turned down from .355 to .300" at the neck to fit the gland and also drilled the bottom to 23/64" and tapped for 1/8" Pipe. I used 5 minute epoxy with acetone wash to seal the threads. I've used this method for the M 712 Broomhandle, The "Duke", SBR, and QR (secondary port) P-08 Lugar etc..etc.. The  Ninja Fill check is the key on almost everything! Funny thing....everyone on this forum is concerned with FPE....get over it! There are other ways of FUN...TOO!  dave

It was your posts the inspired me into HPA for these auto BB guns.
