The "Diamond Cut" Grip Barrel Back is designed for use with Planet Eclipse PWR inserts and the S63 Barrel System. It features a machined diamond-cut pattern for added grip and texture, which makes it easier to disassemble in wet or muddy conditions. The solid design eliminates the stock cut-out window, ensuring the PWR inserts don't stand out, get dirty, or clash with custom-colored markers. It is compatible with the Planet Eclipse S63 Barrel Tip and has a total length of 14.5 inches. Developed from input by Professional Paintball team Infamous, this barrel back combos with the PWR Inserts for accuracy, a quiet shot signature, durability, and all-weather performance, everything that Pro DNA stands for.
