Common Issues Caused by Misaligned Upper Receivers
When it comes to building an AR15, one of the most crucial aspects to pay attention to is the alignment of the upper receiver. The upper receiver is the part of the rifle that houses the bolt carrier group, barrel, and handguard. If the upper receiver is not properly aligned, it can lead to a host of issues that can affect the performance and reliability of the firearm.
One common issue that can arise from a misaligned upper receiver is poor accuracy. When the upper receiver is not aligned correctly with the lower receiver, it can cause the barrel to be slightly off-center. This can result in the bullet not being properly aligned with the bore of the barrel, leading to inconsistent shot placement. Inaccurate shots can be frustrating for any shooter, whether they are using their AR15 for hunting, target shooting, or self-defense.

Another issue that can occur with a misaligned upper receiver is feeding problems. The bolt carrier group relies on the upper receiver to guide it as it cycles back and forth during firing. If the upper receiver is not aligned properly, it can cause the bolt carrier group to bind or get stuck, leading to failures to feed or extract. This can be a dangerous situation, especially in a self-defense scenario where reliability is paramount.
Misaligned upper receivers can also lead to increased wear and tear on the rifle. When the upper receiver is not aligned correctly, it can cause excessive stress on the components of the rifle, leading to premature wear and potential breakage. This can result in costly repairs and downtime for the firearm, which can be frustrating for any gun owner.
In addition to these issues, a misaligned upper receiver can also affect the overall aesthetics of the rifle. A crooked upper receiver can detract from the sleek and streamlined look of an AR15, which is a point of pride for many gun owners. Ensuring that the upper receiver is properly aligned not only improves the performance and reliability of the firearm but also enhances its appearance.
To avoid these common issues caused by misaligned upper receivers, it is important to take the time to properly align the upper receiver during the assembly process. This can be done by carefully installing the barrel into the upper receiver and ensuring that it is properly seated and torqued down. It is also important to check the alignment of the upper and lower receivers using a straight edge or laser bore sight to ensure that they are perfectly aligned.
In conclusion, the alignment of the upper receiver is a critical aspect of building an AR15. A misaligned upper receiver can lead to a host of issues, including poor accuracy, feeding problems, increased wear and tear, and a less-than-ideal appearance. By taking the time to properly align the upper receiver during the assembly process, gun owners can ensure that their AR15 performs reliably and accurately every time they pull the trigger.
