I found a barrel I’m considering as an upgrade, will it fit?
Are these Chinese Norincos (386) very forgiving and compatible with replacement barrels?

Tagged for expert replies. I have one and am concerned about the availability of a replacement barrel as I understand they are dimensionally different. It’s just a blaster but I have put an awful lot of cheap steel case though it.

Usually 386 rifles are forged and 416 are stamped. Neither fit the other.

Why replace a chromed lined military barrel with just a cool looking USA barrel?

A SOT buddy did a finned EU barrel swap on a stamped receiver. Pretty cool but heavy.
