Machined from 4140 chrome moly steel for durability, the deflector measures 2.20 inch in length, weighs 4.7 oz and features a Melonite QPQ finish for enhanced wear and corrosion resistance. Made in USA. Compatible QD mounts include YHM-3102, YHM-4302, YHM-5M2-QD, YHM-4315, YHM-3102-1MB and YHM-3109-1MB. The deflector is not compatible with YHM-3702, YHM-3802, YHM-9923 or YHM-9853.
