This is the the PROFILED PILLAR KIT FOR THE CZ 457
These can be used for after market CZ 457 Stocks, or for the models that do not come from factory with stock pillars installed.
Pillar installation assists in accuracy as it prevents crushing of the stock and prevent stress cracks. Pillars also keep the action from twisting or moving. Consistency is key in accuracy.
The pillars are 1/2'' (.4995) in diameter, CNC machined, and made of T6 6061 aluminum. These pillars are left long so that they can be trimmed to length by the installer, depending on the specific stock that you have. If the pillars are cut too short they will not do their job. The threaded rod is used to assist in placing the pillars and cutting to them to length.
This a DIY kit. In order to utilize this kit you must drill out the stock, and "glue" these into place. Final fit and finish will need to be done during installation. A chamfer may be required on the bottom inner diameter of the pillars to allow for action screw fitment. A drill press is recommended.
I also have Stainless Steel Action Screws and kit for the cz 457
These will only fit the CZ 457 because of the step, I have other pillars that will fit other actions such as the Remington 700, Cz 455, Savage, etc
May fit other rifles that are rimfire, such as ruger, 10/22, savage, anshutz, winchester and the like but I cannot be certain.
The profiling on the pillar help secure a strong bond in the epoxy and stock. To install simply scuff up the exterior with some sand paper prior to installation and be sure to degrease.
Please ask any and all questions before buying.
