I received a NPM Bavarian flipper with a BA barrel. War Baby leads me to believe it's correct.

Harrison states on p. 197, :BUFFALO ARMS Free Issue WWII Carbine barrels.
Documented use C. 1943: National Postal Meter 69,610;......"

Also p. 197, "BUFFALO ARMS/MO-YR National Postal Meter M1 Carbine Barrel. Limited
use throughout production."

Riesh shows p. 49 that NPM used type II Buffalo Arms Barrels dated to (10-43), and
Marlin Type I Barrels (Undated) (Late). Also footnote 4 shows Marlin and
Underwood were Barrels most often installed by NPM.

It is my understanding that Marlin had problems with barrels but finally got them straightened out. On the other hand Buffalo just had a high % of barrel rejections so the ones that passed were up to specs.

Hope this helps !

I have a 4.14 MM NPM (estimated production Q4 1943) with a 9-43 Buffalo Arms barrel. It is also counterbored and shoots very well. It is the bottom one of the four in the picture.

I found out that this carbine is a 4.15 and the bbl is 11-43. To me, that sounds like it probably is the correct bbl. The flip sight is also marked "S" on one side and "N-A" on the other, according to the seller. Would NPM flip sights be marked that way? Thanks!

Buffalo Arms was a supllier of barrels for NPM . I have a service grade with a Buffalo Arms barrel. It shoots a six inch group at 100 yards. That should be good enough for a carbine. Don't know about what was thought of them when they were manufactured but mine shoots straight enough for me. These aren't precision match shooting rifles anyway.
