Gun-tips are a strong and durable replacement for cotton swabs that do not leave lint and fibers behind. They are flexible enough to round corners, but strong enough to resist breaking. Gun-tips are also washable and reusable. The 3 inches Precision Tip swabs are especially effective for triggers and frames, slide rails, barrel links, trigger assemblies, compensators, barrel extension and lug recesses, bolt cams, extractor ports and other hard-to-reach areas. Also great from applying lubrication/grease with pinpoint accuracy. Features: Washable and reusable Lint-free and fiber-free Each tip can be used multiple times
