I let the metallurgist know that Erma's specs were 4130 steel for the receiver.
It turned out really nice.
The stock is beautiful on this gun - it eats any 30 carbine ammo I feed it. And, per M1carbinesinc, it is 100% USGI compatible.
Has sights by Rock-O-La, Inland trigger group, Saginaw guide rod, Inland bolt, Inland barrel.
Only things Erma's are the receiver (heat-treated to USGI Specs) and an Erma's "E" hammer.
