It has an 035 cocking piece but will also come with an 045 cocking piece to help fit the trigger you choose to run, that was an extra $40. It also has an extra firing pin spring that is lighter weight than factory as well. Never fired a single shot. I am selling because I already have a Nucleus filling the same role. I would do $1,225 and we split actual shipping. It will ship within 24 hours after payment received. Make sure your FFL will accept transfers from individuals. If you live in Tennessee I will ship directly to you.
