The Hi-Viz 'Spark' front sight is the preferred sight for our demo guns and barrel builds here at King Armory. They fit several different thread sizes, but we use the 6-48 thread as it is the thickest shank and most durable for hard use. Comes with studs for 5 different thread sizes. The fiberoptic rod in the sight picks up ambient light and makes target acquisition quicker than with a bead. KA-HV01......................................................$8.00

The Butler Creek Protector is the preferred folding stock for the Moss500 here at King Armory. This is one of the best built folders made and will handle any demands you can ask of it.

These are available for sale from our shop or you can add them to your KA work order and we will ship it with your finished KA part. Kit includes the needed mounting hardware and the buttstock.
