SME KnockOut Features The SME KnockOut Gun Rope Cleaner is built around a nylon rope with an attached cleaning brush sized specifically for .50 caliber rifle bores. Pulling the rope through the barrel draws the integrated brush along the full length of the bore lifting fouling and residue out in one continuous pass. The two-pass system design means each pull does more cleaning work than a single-brush rod getting the bore cleaner with less time and effort at the bench. This makes it a practical tool for shooters who want to maintain their rifle between range sessions without breaking out a full cleaning kit. Finished in black and orange the rope is easy to spot and handle even in a cluttered range bag or field pack. Its compact flexible design stores easily in a pocket or kit and deploys in seconds which matters when time between strings of fire is limited. Because it is rope-based rather than a rigid rod it works well in confined spaces or with rifles that are awkward to clean with a traditional cleaning rod. The SME KnockOut Gun Rope Cleaner is a quick effective maintenance tool for any .50 caliber rifle owner.
