The JP Hand Guard Weight Kit comes with two .4 lb. weights, backer plates, and screws, which easily attach to the JP MK III handguard. Because weight and balance are extremely important in precision shooting, owning a set of modular weights is a valuable investment. These weights are low-profile, and will fit into a variety of positions on the handguard. Additionally, with a manganese-phosphate finish and rock-blasted texture, these weights are durable and grip well on bracing surfaces.
