got my prototype M11/AR22 conversion working.

[Shattered]

Very cool! I like it. Now that you have an AR magazine well, when are we going to see a 5.56?

That's kinda like the first thing that floated through my brainpan as well...

 

[shawnr1]

Nice work.

5.56 will never happen.

1: ATF would likelly not aprove of it. they don't like you going up in caliber power, only down.
2: it would require a closed bolt action and gas operation, plus a longer barrel......Too much $$$ and time to make IMO
3: the point was to make the thing cheaper to shoot in the first place, with mags I had on hand allready, 5.56 is going the wrong direction.

BTW, got some video today, and it is running right at 850rpm, which is perfect for me. Strangely suppressing it did not change the ROF. I will try to get the video up this weekend.

Awesome!

why would it have to be closed bolt?

 

[Tobias Arms]

Open bolt on a rifle cartridge would have to be a VERY massive bolt with a VERY strong spring, or a roller locked system....Otherwise kaboom.

wouldn't necessarilly have to be closed bolt, but in order to use standard AR components it would. And that would be the only way to really keep the cost reasonable.

If the gas and locking system was set up correctly the bolt would weight the same or less than a standard m11/9 bolt. open bolt does not have to mean its a blowback operation

 

[J-Ho]

What he said. I bet you could get ahold of some open bolt at parts somewhere. I see them on gunbroker sometimes. I don't remember the model number but there was an open bolt m16.

 

[Tobias Arms]

With enough time and $ I am sure it could be done. But I have no interest in doing it.

Can't really argue with that logic.
I still think it's a very nifty piece of work. What did you use for a barrel?

 

[Junkcollector]

The M231 Port weapon fires from an open bolt but still uses the cam lock of an M16.

 

[Tobias Arms]

Technically it fires from a closed bolt. But operates from an open bolt.

 

[root]

Your project is ......
Well....

GROOVY DUDE!

 

[svtcobra]

very cool! I love those 50 rd ar22 mags from BD.

 

[root]

I have a metric shit ton of those mags for my ar can ya make one for a M/10?

I'd Buy. and I already have a .22 upper that takes ruger 10/22 mags.

 

[Garrett]

I saw a cobbled-together .22 upper about 15 years ago for a MAC-10 that was similar. As with yours, the magwell was moved forward of the MAC frame. But that's where the similarities stopped. It used a lot of 10/22 parts inside some square tubing, and looked like just a haphazard collection of... stuff. Nothing so refined as what you have built.

Bravo!

 

[dtom29]

Are you planning to market this? I know I'd be very interested.

 

[softaildeluxe]

Well....

GROOVY DUDE!

double dude groovy

what type of machining tool set up do you have on hand to create that, doctor frankenstein?

 

[Tobias Arms]

Are you planning to market this? I know I'd be very interested.

I don't have the manufacturing capacity to produce this, and the design still needs some refinement.....but maybe there are some other companies that could handle manufactureing, once I finish the design. There is one local company that I have showed it to (the owner comes to our local subgun matches). If there is enough interest....perhaps it could happen....In time.

 

[9mmsubgun-m11]

I would pay twenty bucks to see and hear Macaholic's reaction to you ripping the heart and soul from this historically significant weapon by creating such a dangerous contraption.

:roflmao He would shit an eggroll if he saw this.
