Sinclair F-Class Rest Leg Extensions are designed to elevate rifle rests when used on the ground in F-Class matches and in varmint shooting. They are approximately 2.5 inches longer than standard rest legs and can be used separately or with F-Class Rest Foot Pads. The extra length elevates the rifle rest out of the mud, grass, and gravel and also can serve to anchor the rest into the ground. Sinclair Leg Extensions will fit all Sinclair generation 2, generation 1 and light weight rests. Not new Heavy Varmint or Competition rests.
