When the T3x rifles came out they made a few changes such as the metal bolt shroud, steel recoil lug and the port on the action. Is their any reason on the T3 and T3x lite rifles that would not allow you to interchange barreled actions on either a T3 or T3x stock. Did they change any dementions on the width or length on the actions or also change anything between the 2 tangs on the back of the actions?
