If that’s not enough, the ARX100 requires little to no lubrication. The “technopolymer” used to make the receiver has sufficient lubricity to allow the rifle’s component parts to operate smoothly. Many lubricants combine with powder residue and dust to form a thick mixture that can compromise reliability. The ARX100 doesn’t have this problem, and that makes this rifle much easier to clean and maintain in the field. Ease of maintenance is further enhanced by the fact that no tools are required to fieldstrip the ARX100.
