An air rifle is a gun that shoots a projectile using compressed gas or air. Many people use air rifles for recreation, target practice or hunting. While shooting, pellet traps are used to capture the pellets shot at the target to prevent them from being spread all over. Commercially-produced air rifle pellet traps can be expensive, but a DIY version can be cost-efficient and simple.
Making the Frame
Measure 3/4-inch plywood into five equal sections measuring 12 inches by 12 inches, and cut with a jigsaw. Four of the sections will form the main box, and the fifth will serve as the backstop. Overlap two of the sections by laying them perpendicular to one another and screw them together. Continue laying a piece perpendicular and screwing together until a box is formed. Fasten the last section on the back side of the box.
Cut an 11-inch by 11-inch piece of styrofoam that will fit the backstop. The styrofoam will help absorb the pressure from the pellets. Use glue or double-sided tape to attach the styrofoam to the backstop on the inside the box.
Target Hanger and Handle
Cut two pieces of 3/4-inch plywood into a 3-inch by 12-inch rectangles. These two pieces will serve as the target hanger and pellet trap on the front of the trap. Screw one piece on the top by lining up the corners of the box to the corner of the plywood. Repeat with the bottom piece by lining up the corners of the box. Screw a small cabinet door handle on the top of the box for easy transport and pin a target on the top piece of plywood.
