After cleaning and inspecting each part, it is crucial to reassemble your AR15 correctly. This includes putting each part back in its proper place and ensuring that all pins and springs are in the correct position. Follow the instructions to put your rifle back together the right way.

Mistake #9: Not Properly Lubricating

After reassembling your AR15, it is crucial to properly lubricate all moving parts. This will ensure that your rifle functions smoothly and prevent any potential malfunctions. It is essential to use a high-quality gun oil or lubricant and apply it sparingly to avoid excess build-up.

Mistake #10: Not Performing a Function Check

After reassembling and lubricating your AR15, it is crucial to perform a function check. This involves checking the safety, trigger, and magazine release to ensure that they are functioning correctly. It is also essential to check the bolt carrier group for proper movement and function.
