We changed the T-shaped Primer Arm Assembly (TP2122) design in 2006, and do not have any T-shaped Primer Arms available.
We no longer manufacture the parts necessary to convert your Turret Press over to the newer primer arm style.
Per our Lee Lifetime Guarantee, we can offer a 50% discount on a new reloading press + tax and shipping. To take advantage of this offer, please send us a photo of the existing Lee Precision product you own, with a photo ID or piece of mail showing your name and address in the same photo. You may respond to this email with the photo and with what product you would like to upgrade to.
