i would'nt mind a norrell selectfire trigger pack for a 10/22 carbine,,,,,
understand he made a ton of em b4 the 86 cutoff and now and then when he needs some cash he puts a few up for sale,they go for thousands.
he doesnt even put anything online until he is ready to sell it so dont go looking,you'll only find gun finish info.
then again he could be out of them in which case good luck finding one,people tend to hang onto them.
the pack id the registered part so when you wear a ruger out just go buy a new one and switch packs,i think the recomended mag is the eagle 30rder ($10)
