CZ 457 Varmint MTR Cheek Riser

The goal was to create a screw-free cheek riser, designed for benchrest-style shooting. The press-fit design may not hold up for more tactical oriented shooting.

The main insert was printed in ASA and fitted with M3 threaded inserts. A flexible TPU layer grips the rifle stock, eliminating the need for drilling.

This was my first attempt at carbon fiber vacuum bagging, and there’s room for improvement—like achieving even bonding with the peel ply.

The results were made using the male version of the mould, which was printed in PETG, sanded to 1500 grit, coated with epoxy and polished to 6000 grit. Followed up with four layers of demoulding wax.

The carbon fiber part was made with three layers of 210gsm 2x2 twill carbon fiber cloth and EL2 laminating epoxy, followed by peel ply and breather cloth. Vacuum bagging was done using a standard vacuum cleaner and storage vacuum bags, resulting in a 0.75mm thick carbon fiber part.

Contours were sketched using a paper template, cut to size with a Dremel abrasive disc, and holes were made with a Dremel router bit.

Next steps:

• Creating a hole drilling jig
• Testing of the female mould
