Question about a CZ 455 action

[whale]

Is the action of a CZ455 threaded or pinned? I was thinking about getting an action job done. Thank you.

Neither. The design of the action allows for drop in barrels not unlike the Ruger */22 series. The barrel is held in by two set screws.

Lilja makes a drop in barrel for the action and below is their barrel installation instructions.

Installation Instructions

To remove original barrel:

1. Loosen the two angled metric set screws in the bottom of the receiver ring using a 3mm Allen wrench.

2. The original barrel will then pull straight out of the receiver.

To install new barrel:

1. Slide the new barrel into receiver being careful to align the flat at 6:00 on the barrel with the notch in the receiver.

2. Tighten the two angled set screws. This pulls the barrel into the receiver and also sets the headspace.

The receiver stock screws are a T-27 Torx head.
