452 Varmint, Lux, Ultra LUX, Trainer and Special

The action screw "Kit" fits SOME 452 Lux & Trainer models chambered in .17HMR with a plastic magazine well. Please check your action screw shaft length before you order. The complete "Kit" has all 3 of the screws and features a #20 Torx(star) head drive. These are high quality custom machined in the USA with USA made raw materials. The head design is such that the screws fit almost 100% perfectly flush with the trigger guard. The star(Torx) drive allows better drive contact area for a non-slip drive every time with minimal wear on the screw and driver bit.

We recommend you start your action screw torque at about 18 inch pounds on the 2 action screws and work up from that point 2 inch pounds at a time until you find your best group size but no more then 32-34 inch pounds. The wood screw only needs to be snug. Our experience has found that a 20 inch pound torque seems to work well for the best group size with most available ammo.

Please check the shaft length of your screws before making your selection:
Long Action Screw 1.25"(33mm)
Short Barrel Screw 1.05"(27mm) 
1 Wood screws

*Minor fitting may be required.
