Bore-Max Speed Jag Patches are a component of the Bore-Max Speed Clean System for faster and easier bore cleaning. Sized to account precisely for both the jag diameter and patch thickness this combo provides the optimal compression to thoroughly and consistently reach into the lands and grooves. Tight enough to provide superior compression within the bore while still remaining relatively easy to push through. Speed Jag and Patch system gets more patch material in the bore, eliminates bunching and maximizes the effectiveness of each pass-through. Speed Patches are a synthetic material that that has shown superior absorbency over cotton and is better at absorbing fouling and spent solvent i Mfg: Real Avid
