Bulk .35 Caliber / 9mm Rifle Phosphor Bronze Bore Brushes, w/8-32 Aluminum Stud [Quantity: 12]. Made in the USA! This precision designed phosphor bronze bore brush features rounded, smooth bristle tips. The straight, thicker wire bristles (rather than crimped) offer more effective cleaning power. This brush will not easily bend with force down the bore, and will not damage the grooved rifling. Constructed of aluminum and steel with phosphorous bronze bristles. We carry most calibers of brushes and mops, let us know what you need and we’ll get it listed here on eBay for you. Stock photo above, may not be pictured in the correct caliber, however you will be shipped the correct caliber. NOTE: UPS and FedEx will not be used for deliveries to PO Boxes, APO/FPO/DPO, and the US Protectorates–orders placed as such will either be canceled or shipped via the Postal System at our discretion. NOTICE:   Though operating under a skeleton crew at our warehouse, most orders should ship as normal with minimal delay.  I apologize for any inconvenience, and wish everyone well.  Peter J.
