Product Summary
The Black Dog Machine Bolt Saver is a molded polymer dust shield designed to protect your AR-15 components during transport or storage. It fits securely into the underside of a disassembled .22 conversion upper receiver or a standard AR-15 upper to prevent the bolt from falling out. The shield is easy to install by sliding it over the front and rear take-down pins and securing it with two cotter-style push pins. This is an essential accessory for shooters looking to keep dirt and debris out of internal components while their firearms are disassembled.
