Scrubs Lug Recesses Clean For Secure Bolt Lockup & Reliable Cycling

Easy-to-use cleaning tool helps remove accumulated powder residue, grease, and carbon from AR-15 lug recesses. Helps ensure secure bolt lockup, reliable cycling, and consistent accuracy. Simply remove the bolt, bolt carrier, and charging handle, and insert the tool with the disposable cotton cleaning tip retracted into the protective sleeve of solvent-resistant Delrin®. When the sleeve bottoms out on the barrel extension, push a little farther to expand the cleaning tip in the lug recesses, rotate the tool several times, and remove. Also perfect for cleaning the barrel extension face. May be used dry or with your favorite bore cleaning solvent.
