Default Winchester vs. Korean Gas Cylinders (GCs) - Wide Base only

***** Korea only made wide base GCs. This post only addresses the wide base Winchester and all the Korean GCs. *****

There are some easily recognizable differences and many small ones.

The major differences between the Winchester and all the Korean GCs are;
(1) the lack of bevel (radiused toe) on the bayonet lug of the Winchester.
(2) the step beneath the front site mount on the Winchester.
(3) the surface of the Winchester is generally more porous looking than the Korean, which has a much smoother surface.

Also the Round Barrel Ring Top
- Only Winchester and the Korean GCs had a round barrel ring top as shown in the 2nd picture below.
- The SA, HRA, and IHC barrel rings had a flat area on the top.
- The Winchester was rounded off by manual filing so these filing marks are usually easy to spot.

Thanks - how many Korean and WRA GC's did you have in your sample database to make these comparisons?

SA, HRA, IHC, and the Koreans all have the beveled bayonet lug. WRA is the only one that doesn't.

First, thank you for the illustrated characteristics of a Winchester gas cylinder.

Question: with the above quote, how do I tell the difference between an SA, HRA, and IHC gas cylider? I have an unmarked cylinder that I am planning on putting up for sale and I can only guess that it is either SA or HRA.

I can't tell the difference. I think the staking may have something to do with it. Perhaps others can chime in.

HRA gas cylinder if original will be a more slick finish. Cant always go by staking as swivels could be replaced

I received a gas cylinder with the last SA Service Grasde I purchased from the CMP. The gas cylinder has a K stamped onto the bottom of the bayonet lug. Is this an indicator of manufacturer?

I have a WRA with a C and was told it didn't mean anything.

You can read the thread I posted under my name.

Default WRA bayonet lug

rkohut

I have done research on WRA gas cylinders as well and I came across pictures showing that some WRA gas cylinders have a very small bevel on them; I have a Korean as well and the bevel is quite large in comparison. The gas cylinders I have, have the round rear ring, ledge below front sight and other than the very small bevel on the lug they match. I compared it to a narrow base WRA that I got from an M1D off the floor in Anniston and it as well has a very small bevel on the lug. Please advise if WRA did in fact have a very small bevel on the lug. Your help is greatly appreciated.
