Next, it is crucial to inspect the upper receiver assembly for any signs of wear and tear, corrosion, or damage. Any damaged or worn out parts should be replaced immediately to ensure the proper functioning of the firearm.
Additionally, it is recommended to lubricate the upper receiver assembly with a high-quality gun oil to prevent any friction and wear on moving parts.
Lastly, storing the AR 15 in a dry and cool place can prevent any rust or corrosion from occurring on the upper receiver assembly.
By following these maintenance and care tips, the AR 15 upper receiver assembly can function properly and last for many years to come.
What is the difference between a stripped upper receiver and a complete upper receiver assembly?
A stripped upper receiver is simply the upper portion of an AR-15 rifle that has been machined and finished but lacks the necessary components to make it functional. These components typically include the barrel, bolt carrier group, charging handle, and handguard. On the other hand, a complete upper receiver assembly includes all of the necessary components to make it functional, including the stripped upper receiver, barrel, bolt carrier group, charging handle, and handguard.
The advantage of a stripped upper receiver is that it allows for greater customization and flexibility in building one's own rifle. For example, one can choose their preferred barrel length, handguard style, and other components to suit their individual needs and preferences. However, a complete upper receiver assembly is more convenient for those who may not have the necessary tools or expertise to assemble a rifle from scratch. It also ensures that all the components are compatible and properly assembled, reducing the risk of malfunctions or accidents.
