Universal M1 Carbine Slide for Late Model Carbines
- Thread starter jski
- Start date
"4130 alloy is noted for its weldability by all of the commercial methods."
4140 is not very "weldable". And this slide has a weld in it.

Update: Universal M1 Carbine Slide Late Model
https://www.gunbroker.com/item/788585662
Aside: I've always wonder, had the late model Universal M1 Carbine design been implemented with high grade, top quality steel would it have proven to be a better design than the GI design? Heresy! I know.

"...would it have proven to be a better design..." No. It's not just the poorly made, stamped, op handle that makes late model Universals junkers. Mind you, a buddy of mine had one that never gave him any grief.
Real Carbines, from 10 different makers and hundreds of parts makers, were used in several wars in all kinds of really crappy conditions from salt water, sand and the really, really crappy conditions of Korea and just worked.

The GI M1 Carbine was not without reliability issues:
Forgotten Weapons: KEN HACKATHORN ON THE M1 CARBINE: REPUTATION VS REALITY
And the Universal M1 Carbine late Model has its supporters:
M1 Carbines Incorporated: Post WWII Commercially Manufactured M1 Carbines (U.S.A.)
The dual recoil springs and bolt design seem to be recognized as improvements. The only thing needed for the often criticized late model slide design is "4130 steel heat treated to 35Rc".

Early Universals used all GI parts on newly-made receivers

I disagree on the weldability of 4140. Place I retired from did it regularly. It needs to be pre-heated, welded with the right wire and post heated to cool down.
