Can be made for full auto lowers, but rrquires a disconnector rod to trip the auto sear. That way it will only work if you have a full auto lower.

Do you think I should make some production prototypes?

My next hurdle will be to make sure it feeds 9mm hollow points. Feed ramp is basically the same as a m-11/9. Many configurations are possible.
I have the basic dimensions now, And can have the parts cut by a water jet cutter. With the right welder, heat treating process and finish coating, It will look just as good as anything out there. the magic is, just pop 2 pins, and pop it on. No lower mods. A lot of firepower and weighs as much as an uzi smg with a 25 round mag, but with 4 times the ammo. |

I used an ncstar (uds) urban dot sight. With 2 angle sights to make a kind of periscope to get the bore and the red dot closer together. The calico pistols and rifles, have a bore to sight distance that is 3 inches or more, This is a very crude prototype. It has been cut and re-welded multiple times. It basically uses a cobray/mac 9mm bolt flipped upside down, for top feed. Hence the left hand ejection. If I can find some one who can make a cobray bolt with left hand ejection. The weapon will eject on the right hand side. Master piece arms offers a 16 barrel and handguard for carbines. Or you can use standard mac 9mm barrels for pistols, sbr's or smg's.
Here is a link on weaponeer and uzi talk,if you want to see build progress and videos. http://www.weaponeer.net/forum/forum_posts.asp?TID=11018&PN=1&TPN=1 http://www.uzitalk.com/forums/showthread.php?77335-Carmac-Calico-AR-15-MAC-9mm-Upper But just remember. This is a build concept. I just finally have the gremlins and measurements worked out. If there is interest I can make a few. Water jet cut and welded properly. Heat treating and phosphate. Or whatever coating is popular this week. The most expensive part is the bolt at $116 bucks. Parts and material are not very much. Very simple design. It can go anywhere from here. |

I like the creativity and ingenuity. However it's a specific niche that isn't very large. How available and expensive are Calico drums? Are they known for reliability and even a 50 round drum seems like it would be heavy and awkward on top of the weapon.

Think you'll go for the bottom eject through the AR magwell?
|

Posted: 7/6/2015 3:09:10 PM EDT
[#18]
Bottom ejection is possible with a custom bolt.
Cdnn has the drums cheaper. They are as reliable as most anything out there. http://www.cdnnsports.com/50rd-9mm-calico-drum.html#.VZrRrGd0yDB http://www.cdnnsports.com/9mm-100rd-calico-drum.html#.VZrRrWd0yDB |

I always wanted to see an upper made to use an American 180 style magazine.
Have it feed from the top and eject out of the magazine well. A nice 150-200 round plate mag would be awesome on a full auto lower. Making it even cooler would be if you could make the bolt reversible so that it could then feed from regular magazines feeding from the bottom and ejecting out the top... |

In its current configuration.... That was my next step. I have a promag magwell adaptor, and was going to see if I could make it dual feed. But it seems everyone wants downward ejection through the magwell. Now this was made with off the shelf stuff. A custom bolt could be made for that, at of course, greater expense....

According to UZI'S own website. The 9mm uzi comes in at 8.8lbs with a short barrel, folding buttstock and a loaded 25 rounded metal mag. The prototype matches that weight almost exactly. But with 4 times the amount of rounds.

A bison type feed is possible. Another builder said he did it. I have a couple other prototypes I want to build using that set up.
Ler scope and periscope is an idea I can try on the current prototype. Let me see if I can upload some pics. |

If you make a short barreled version for those of us with SBR Lowers, I would buy one in a sec.
Are the magazines just the standard Calico Mag? Are they hard to find? |
