Abstract

This study compares three materials (beech wood, ABS resin, and PP resin) for the Mauser M18 Pure Max rifle stock using the Finite Element Analysis (FEA) method. Through 3D modeling and static load simulations (recoil of 16,118 N and 1.5× load), data on stress, strain, safety factor, and displacement were obtained. Under normal loading, beech and ABS were safe (safety factors of 1.34 and 1.91), while PP was unsafe (0.42). At 1.5× load, only ABS remained within acceptable limits (safety factor = 1.28), while beech and PP exceeded yield strength. In conclusion, ABS resin is the most optimal material for the rifle stock due to its superior mechanical strength, durability, and safety.
