Very well machined and smooth action - Jacob Grey Firearms Ultralight 7.62x39mm Complete Upper Assembly

Everythfrom the barrel to the handguard is very nicely machined and finished. The bcg cycles like a much higher end bcg that is smooth like higher end finishes. I also like the charging handle. It does weigh around 3lbs 15ozs but it is lightweight with the heavy barrel profile. The carbine length was definitely the way to go, especially for the hard hitting 7.62x39 ammo in an ar15 platform.
