M14 Gas Cylinder Plug Thread Size

**kenjay** · 11-22-2009 11:30 PM

Hey everyone,

Could anyone help me out and tell me what the thread size is on the gas plug for the M14 icon

(or M1a, I think they're interchangeable between the two)?

Thanks!!
Ken

A Collector's View - The SMLE Short Magazine Lee Enfield 1903-1989. It is 300 8.5x11 inch pages with 1,000+ photo’s, most in color, and each book is serial-numbered. Covering the SMLE from 1903 to the end of production in India in 1989 it looks at how each model differs and manufacturer differences from a collecting point of view along with the major accessories that could be attached to the rifle. For the record this is not a moneymaker, I hope just to break even, eventually, at $80/book plus shipping. In the USA shipping is $5.00 for media mail. I will accept PayPal, Zelle, MO and good old checks (and cash if you want to stop by for a tour!). CLICK BANNER to send me a PM for International pricing and shipping.

I don't know the thread but the parts are interchangeable between M14 and M1A icon

. M1A just lacks the full auto ability.
