G3 Bolt Locking Roller (Pair) - Used

The G3 Bolt Locking Roller (Pair) is a component used in various mechanical systems, particularly in firearms such as the Heckler & Koch G3 rifle. This pair of rollers is part of the locking mechanism of the bolt assembly. When the rifle is fired, the bolt moves backward to extract and eject the spent cartridge case and then moves forward to chamber a new round from the magazine. The locking rollers play a crucial role in ensuring that the bolt locks securely into the barrel extension during the firing process, thereby containing the high-pressure gases generated by the ignited cartridge. This helps maintain the integrity of the firearm and ensures safe and reliable operation. Used rollers may show signs of wear but should still function effectively within specified tolerances. Regular inspection and maintenance are recommended to ensure proper functioning and longevity of the firearm.
