Noreen Jig sets are no longer available
Make your 223/556 80% receiver finishing a breeze with the Noreen Firearms AR15 Billet 80% Lower Receiver Jig Set. Steel side plates add maximum fit and durability. Machined from billet steel and aluminum.
Works well with Noreen Firearms 80% receivers.
Will not work with all lower receivers.
Used it twice with my mini-mill. Dimensions very accurate. Both trigger groups function well. I do recommend using a 3/8” carbide end mill.
