The Flapper is made out out of steel and parkerized.

The Chinese made the Buttplate out of Steel, not USGI.

Just to clarify the plungers. The earliest buttplates (no flapper) were standard Garand. The Garand buttplate had no locking device on the door. It used a rear plunger which was under spring tension. The M14 buttplate had a door lock (front) which must be depressed to open. This design had both a rear tension plunger and the lock.

It has been about 25 years since I disassembled an M14 buttplate so my memory is clouded. If I recall the ball bearing is under spring pressure and keeps the flapper in the opened and closed positions. I guess I never disassembled one with a plunger. NEW INFORMATION thank you guys.

Naturally the ball bearing would not be present in the early Garand buttplates without the flapper.


Ditto to what Lex_Ordo posted.

I've edited my 10-16-05 post to use the term "lock" for the trap door as applicable.

What we are witnessing is the beginning of an area of research that has not been done before. Although it is new and possibly confusion, in a few years it will be part of the knowledge base of buttplates and understandable. My hat is off to all who contribute.

I think I have a 1B. Textured on the lower part and smooth on the upper part except for two dimples above the top screw.

Different do you have a picture of 1A? I have never seen one with no lock and would love to see it.

Questions for R4 fan on the buttplate without the door lock:

Does the door remain closed or is it loose?

Could you use a magnet to see if the door is steel of aluminum?

I am trying to determine if the lock is just missing. If there is a cavity where the lock belongs, I suspect that is the case. The Garand had a long plunger that was the whole width of the door. But the Garand's door was steel.

Thanks.

pfin has the buttplate, not me (R4 fan). Here's an enlargement of pfin's photo of the buttplate without the lock on the door.

Heres what I have ,the one on the left is marked KMT and is on a H&R marked walnut stock,The one on the right is unmarked and is on a birch stock that has this marking under trapdoor.
Dont see much difference in these two exept the dimples are smaller on the right one.

IRON WORKER, left to right, you have Types 2C and 2D flappered butt plates. So, KMT made Type 2C for sure. Cool. Also, the photo of the stock marking shows it to be made by Sykes Manufacturing. They made replacement M14 stocks for the USGI Springfield Armory.

Here is my entry.

This Butt Plate is steel with an aluminum trap door. The door has a latch. Ther are 2 raised dimples on the flapper and a hole on one side of the butt plate. Note the grinding marks on the butt plate. Is this a Chinese butt plate or G.I.? This was on a refinished G.I. stock I bought from Numrich Arms in 1994.

I did some further inspection on my butt plates. Type 2A differs from the others as far as I can see in that it has truncated (cut off) looking corners at the top outboard of the hinge slots.

Ox,

I have 13 of those buttplates which I am returning to the person I bought them from. I believe that they are all chinese. I have some with worse grinding marks. I'll see if I can take some photos before I ship them all back.

R4 fan,
I thought I heard that the Chinese butt plates, because they are steel, were desirable. Is the trap door on your butt plates aluminum or steel?

Regards
