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 6 inches Extended Reach swabs are especially effective for triggers and frames, slide rails, lug recesses, gas ports, AR bolts and gas keys, bolt flutes, extractor ports and any other hard-to-reach area. Features: Washable and reusable Lint-free and fiber-free Each tip can be used multiple times
