Hence the

I would like to build an ar one day though. At least I can shoot that around here.

Until the grip/fore-end gets too chilly......... You'll need a tactical cozy!!

I'm thinking about building a 1/3 scale .22 caliber Gatling gun.

We've also discussed scaling it up to accept .410 shot shells.

Discuss.

22 is cheapest.

there is still plenty of cheap tokarev ammo around now

545x39 is still cheapish too

A machinist friend of mine machines matched AR style uppers and lowers.  Makes some with threaded barrel setups.  Nice looking and darn accurate. (not that you can't get some pretty plain jane AR parts together to shoot excellently)

what is a "threaded barrel" setup, do you mean the muzzle or chamber end? 

muzzles are threaded by norm, but i'd assume you knew that.

i'll post pics of my Tokarev AR SBR when its finished.

He built some receivers that took threaded barrel shanks instead of nut and shoulder arrangement of a typical AR - really expands your options as far as barrels - both in configuration and quality.  Most of his guns are set up for long range varmints and target shooting, with long, heavy profile barrels.

that's pretty slick

what i'd really want is a QC barrel setup like the FND or some other bigger mg.  I think rifle designs suffer from not having that as it would make assembly and field service much much easier without much overhead in the design.

the Daewoo AR has close to a QC barrel design, with just a single pin holding it -- the barrel is indexed against the receiver and since the bolt locks onto the barrel like an AR15, there isn't much issue with headspacing.  that's my biggest pregnant dog about the FAL, headspacing a build and indexing the barrel.

One issue with .410 gatling would be extraction.  There is a lot of drag with the expanded plastic hull sliding out of the chamber.  I did a bit of messing around with a Taurus Judge and was suprised how hard extraction was.  But, as with most things, I'm sure some smart, creative people can overcome little problems like that.

Once, at the Second Chance combat shoot in Michigan a guy showed up with two gatlings, one in 45-70 and the other in 9mm.  He had big fiber drums full of surplus Egyptian 9mm and burned it up by the 5 gallon bucket. 

Colt is currently making a limited run of 45-70 Gatlings - they are utterly beautiful.  Dealer price is $39500. 

Perhaps a fluted chamber would aid extraction, that is what hk did with the p7 series pistol!

And the MP5. HK spent brass is easy to ID.

Especially when they put it in the magazine backwards.

That's a dead giveaway

That is an awfully embarrassing picture.
