M2 parts in M1?

[mhess]

Is it against ATF laws to have a M2 trigger housing and slide in a M1 with no other M2 parts ?

No. Some of the late Winchester and Inland M1 carbines have these parts as mfgd.

You just can't have all the significant M2 parts together, whether installed in a carbine or not.

I am not sure what Inland44's definition of all the significant M2 parts is, but some of the late Winchester M1 carbines had all the following parts:

M2 trigger housing, M2 sear, M2 slide, M2 stock, round bolt, and M2 mag catch. That combination shouldn't be a problem. I suspect some of the late M1 Inlands also had the same combination.

Having only a M2 trigger housing and M2 slide without access to the rest of the parts shouldn't be a problem.

The problems with the BATF "regulations" is that they are sometimes subject to interpretation by the particular agent. The same "rules" don't always apply to all weapons. Simply putting a M16 bolt carrier in a AR-15 is usually viewed as intent to construct a machine gun, even though that part may be incompatable with all the other parts in the lower and upper.

To extend upon on what Inland44 stated. You can't even have access to all the parts. If you have some of the parts and give some of the parts to your neighbor to store in his garage, you have access and a possible trip to the pen. It isn't worth pushing the envelope on this one.

The round bolt and the mag catch with the additional support finger are not specific to an M2 carbine.

Interesting. The ATF classifies the M-2 hammer as part of an M-2 kit, but Plainfield shipped commercial M-1s with M-2 hammers installed. I bought one used in 1974. The space occupied by the disconnector was taken up with a washer from the hardware store.

It's not MY definition, its THEIR definition. Look it up. I didn't say because I wasn't sure I'd remember which were significant and which weren't. On a matter like this, you would not bet your next ten tears on anybody's opinion anyway. You're going to need to get that from an official source like Brian linked.

The link that BrianQ provided states the following concerning M2 parts that can function in either either automatic or semiautomatic means:

"While other parts such as an M2 sear, operating slide, trigger housing and stock are used in the fully automatic carbine, these parts are appropriate for use in semiautomatic M1 carbines. Therefore, the M2 sear, operating slilde, trigger housing and stock are not a combination of parts designed and intended for use in converting a weapon into a machinegun."

Accordiing to this statement from the BATF website, the combination encountered on original late M1 Winchesters (and presumably late M1 carbines) that that have M2 trigger housings, M2 slides, M2 sears, and M2 stocks should not be an issue. I have seen original M1 Winchesters in this configuration and I suspect very late Inlands were configured this way also, but I have not personally observed such Inlands.

I have not been visited by representatives from the BATF, but I have been told that agents have been known to take latitude in their interpretation of the agency guidelines or regulations. I would er on the side of caution. In your own mind you can fully comply with all the regulations and still find youself in an uncomfortable position and seeking legal help.

FYI the BATF has changed their ruling on using M16 carriers in AR15s.

Almost all AR15s including Colts ship with M16 bolt carriers and have for sometime now.

Infact Colt went to great detail proving that the heavier bolt carrier was more reliable in a semi auto AR15 carbine and in no way would make it full auto. They had alot to do with this change in ruling

Not a problem. There is tons of bandwidth dedicated to this very subject on AR15.com.

OP most of these type of questions can be answerd on the ATF website or even with a phone call to the ATF.

I have a late Inland that was manufactured (in March, 1945) just prior to the conversion to M2. The Carbine Receiver ring (which is the key) has a hand stamped "1" just after the "M". Because it is an M1 Carbine, I would not have any legal problems, If, however, the Carbine was stamped with a "2", then the ATF considers it a machine gun. M1 Carbines manufactured at that time (March, 1945) would have "late" parts, in which several parts were also used in M2 Carbine production.
