Quality is poor:
Lots of QC issues on the “new” Inland carbines.
If you want a reproduction M1 carbine that is actually dependable and properly made, you’ll have to pony up for a Fulton Armory. They are hand built and they’ve got a 9 month lead time right now. Fulton Armory uses an extremely high quality Lewis Machine & Tool milled billet receiver and Criterion match grade barrel. All the parts are 100% USGI spec. They are not cheap rifles but many consider them as good, and in some ways even better, than original WW2 carbines as far as build quality go.
But honestly, just get a USGI rifle to begin with. Unless you have a specific requirement for a replica carbine, such as wanting to compete in target competitions where the brand new match barrel will be of benefit, or you don’t want to put wear and tear on an aging original, you’re better off just getting a USGI rifle.
