WTK: Demilled Semi Auto M1927A1 Thompson


Recommended Posts

Recently got a semi auto parts kit from a auction company who sells estate stuff out of California. The rifle is in an unfired condition, few if any handling marks.

 

Problem, the reciever was chopped up and its missing the 2nd section in the middle.

Is it possible to make some pieces and weld it back together to make it a rifle or would it be more complicated?

 

Or would there be anyone out there who could make it functional again?

 

I more or less bought it for all the other parts but turning it into a functional rifle would be neat as well.

 

Or might just sell the demilled reciever, it's got great sights and a new barrel.

 

Also the auction company has another kit, this time an SBR "Pistol" set. Detachable stock and 10.5 finned barrel. It has 2.25 out of 3 pieces of a reciever. I don't really want to buy it, but the info is out there.

And I don't think I was supposed to blab about them offering me a parts kit outside of auction so I won't say their name. I can buy it for the same price they sold the last kit I bought. (Which was 800 and with GB taxes/shipping came out to $950)

 

And they are only offering it because I was the winner so I get dibs on this other kit?

 

 

Also, that's what I was thinking Dan, the Tommy is just a rectangular box. If you don't mind me asking how much did that run you for the M1A1?

 

Also because it's demilled it'd have to get a serial and become a registered semi auto rifle, would the machinist that would build it have to do that or would another specialty be required like an engraver?

I don't think you have a bargain here. Maybe expect to pay 200 bucks for a machine shop to build you a center section. Then more money to get it welded together. Opinions vary greatly on the desirability of a welded receiver. I did this back when sarco kits were about three hundred bucks. if you asked nicely you could get an extra rear receiver section to use for the missing center sometimes. I built a Tommy gun out of four cut sections once!

 

As far as the build if you do all the work yourself you just build it there's no restriction on building a semi auto gun for yourself. (Kind of like the ar15 unfinished lowers). If I built it as a licensed manufacturer I would give it a serial number and engeave my maker information and it would go in my bound book and then it would transfer back out on a 4473.

Like I said, I bought it for the brand new parts and detachable stock,which a semi auto lower like that without the rest of the gun is insanely expensive.

 

I could re weld it myself, just need to borrow or buy a hand welder. $200 for a center section isn't bad,I would love just to have it be lined up so there isn't too much room, or not a lot.

 

Ah so if it was made into a live reciever that manufacturer/machinist would be doing the serial and all that themselves.

 

Especially when the price of a Kahr 1927A1 is close to $1300 on its lowest value. That's without the neat detachable stock varation.

 

Thanks for clearing all that up.

you will need alignment jig and overall length gig to hold every thing all correct , then milling machine to mill down welds,, its not exactly a simple project unless you have some skills,, most machine shops i know in this area have been visit from the man warning them about working on parts kits and they should get FFL mfg licence to work on this stuff, most shops wont touch with 10 foot pole, just sayn

Not sure about the OP's machinist or welding skills but manufacturing a center section, welding it (correctly) in place , milling it to spec and fitting it all together will be a job for someone with good skills, experience and time.

OP says he paid $800 for kit ?

A USED but un abused semi can be found for $1000 -1200 if you shop around.

With some minor work most can be made to run well.

 

$800 plus price of welding, machining and assembly does not sound like a bargain.

Bay,

 

Do you know what grade of steel the receiver is? There have been stories around that the Kahr, if it is a Kahr, semi receivers are 12L14 steel. This is a leaded steel, mostly used for screw machine parts, that is very easy to machine but will not weld well.

It's a West Hurley Thompson. Bolt is marked 10 and has some other pretty notable features. It's a steel, not aluminum reciever. I have no idea how to find out what kind of steel it is. Light Grey bluing, not exactly Parkerized either. 1927A1 with a Detachable stock.

 

And to answer the question from 68coupe, it came from California. It even had a California complaint grip.

 

I'm currently trying to get a jig for like $50 and I'm probably going to wait until next next week to get another reciever.

 

I need like 2 inches of it and paying $325 for a rusted demilled 1928 reciever ain't on my to do list.

 

Also it's a saw cut 1927A1, if I didn't mention that.
