The appeal is obvious: You can build an AR-15 without breaking the bank. This affordability is a major draw, and it’s one of the primary reasons for BCA’s popularity. However, to make these prices competitive, certain compromises are often made in the manufacturing process, which can sometimes lead to issues. This is not to universally condemn BCA, but rather to highlight a crucial aspect of informed firearm ownership. Understanding these potential challenges allows you to make informed decisions and potentially avoid frustration down the line.
Common Issues Reported with Bear Creek Arsenal Uppers
One of the most fundamental areas of concern revolves around the reliable cycling of ammunition. Extraction, the process of removing a spent casing from the chamber, and ejection, sending the casing clear of the firearm, are both critical for smooth operation. Problems here can significantly impact the shooter’s experience, leading to stoppages and potential malfunctions.
Extraction and Ejection Problems
Extraction issues frequently manifest as a failure to extract (FTE). The spent casing remains stubbornly lodged in the chamber. This can halt the shooting process, requiring the shooter to manually clear the malfunction, a time-consuming and potentially dangerous situation. You might find yourself using a cleaning rod or other implement to dislodge the stuck case. Visual cues include the bolt carrier failing to fully retract, or the spent casing still visible within the chamber.
Ejection problems, on the other hand, often present as a failure to eject (FTEj). The spent casing might get caught within the receiver, obstructing the bolt carrier’s movement. The casing can jam, creating a “stovepipe” where it gets caught vertically between the bolt carrier and the ejection port. This type of malfunction can require some skillful manipulation to remove the offending case. The visual signs of an FTEj are clear: the spent casing is not cleared properly and is interfering with the normal operation of the rifle.
Feeding Issues
Feeding issues, the smooth and consistent process of loading a fresh round into the chamber, can create a frustrating shooting experience, immediately halting the firing process.
The most common of these is failure to feed (FTF). The round fails to travel smoothly from the magazine and into the chamber. This can manifest in many ways: the bullet might be caught on the feed ramps, the cartridge might fail to completely enter the chamber, or the bolt might simply fail to strip a round from the magazine altogether.
Accuracy Concerns
Accuracy, the ability to consistently place shots on target, is a critical performance indicator. While budget uppers can offer acceptable accuracy for many shooters, some may encounter issues that impact their ability to consistently group shots.
Problems in accuracy can appear in several ways. Shots might consistently group to one side or another, creating a need for sight adjustments. Inconsistent groupings, with shots scattered across the target, are another sign of potential problems. Keyholing, where the bullet tumbles in flight, resulting in oblong holes in the target, is a serious indicator of a significant issue.
Durability and Wear Issues
The AR-15, especially with frequent use, is subjected to wear and tear. While not typically a cause for concern at lower round counts, prolonged use or improper maintenance can accelerate wear.
Causes and Potential Solutions
Several factors can contribute to both FTE and FTEj problems. A weak or worn extractor spring may fail to provide sufficient grip on the cartridge case rim. This can allow the case to slip free before being extracted. Inspection of the extractor claw and its associated spring is crucial. Replacement with a stronger spring or even an upgraded extractor is a common solution.
The chamber itself is another critical area. Roughness or improper dimensions within the chamber can hinder extraction. The spent casing can become stuck due to friction or a tight fit. Polishing the chamber or, in some cases, reaming it by a qualified gunsmith may resolve these problems.
The gas system, the heart of the AR-15’s cycling process, also plays a vital role. Insufficient gas pressure, which can result from an incorrectly sized gas port or misalignment of the gas block, might prevent the bolt carrier from cycling fully, leading to extraction issues. Conversely, excessive gas pressure can create other problems, such as accelerated wear and tear, so a careful assessment is needed.
Finally, the buffer system (buffer weight and spring) can also be the culprit. An improperly matched buffer and spring combination can impede the bolt carrier’s movement, leading to cycling problems. Experimenting with different buffer weights or spring rates could improve extraction and ejection reliability.
The magazine itself is often the first point of investigation. Damaged, worn, or incorrect magazines can easily cause feeding problems. Using high-quality magazines, and inspecting them for damage regularly, can significantly reduce FTF occurrences. Make sure your magazine is of the proper type for the cartridge you are using.
The feed ramps, angled surfaces within the upper receiver that guide the bullet into the chamber, are another key area. Rough or misaligned feed ramps can catch the bullet and prevent smooth feeding. Polishing the feed ramps can help create a smoother transition.
A gas system that’s not providing sufficient pressure can also contribute to feeding problems, particularly if the bolt carrier isn’t cycling with enough force to strip the round from the magazine.
Improperly matched buffer weights or spring combinations can also negatively impact feeding. Insufficient buffer weight might allow the bolt carrier to cycle too quickly, causing it to “outrun” the magazine. The same issue can occur with a weak or worn magazine spring.
Barrel quality is a primary factor influencing accuracy. Manufacturing imperfections, such as inconsistent rifling or minor bore diameter variations, can affect bullet trajectory and lead to accuracy problems. If accuracy is a high priority, investing in a higher-quality barrel is frequently recommended.
The crown of the barrel, the recessed area at the muzzle, is crucial for consistent bullet exit. Damage to the crown, or an uneven crown, can disrupt the bullet’s flight path, leading to inaccuracy. Inspecting the crown and ensuring it’s clean and undamaged is essential.
Loose components can also impact accuracy. The barrel nut, which secures the barrel to the upper receiver, should be properly torqued. Likewise, the handguard attachment should be secure, preventing movement that can affect the barrel’s alignment.
The ammunition used can impact the accuracy of the rifle. Using different loads can yield different groupings. Experiment with different types of ammunition to find what works best for your rifle.
Wear on components can manifest in a variety of ways. Finish issues such as excessive scratching or flaking paint.
Preventative Measures and Best Practices
Regular cleaning and lubrication are essential. A build up of carbon fouling can, over time, interfere with the operation of the rifle. Lubrication protects the parts from wear and tear.
Proper ammunition selection can help. Using ammunition that does not meet the specifications of the rifle can increase wear.
Component compatibility is essential. Ensure all components are compatible with one another and properly installed to reduce wear.
Warranty and Customer Service
Bear Creek Arsenal offers a warranty on its products. Before working on your upper, review the warranty information. If you suspect the issues are the result of a manufacturing defect, contacting BCA’s customer service is a reasonable first step.
If you suspect a problem, documented issues are invaluable when contacting customer service or diagnosing the issues. Take photos or videos of malfunctions. Note the type of ammunition used, the environmental conditions, and the type of magazine.
Comparison with Other Upper Receivers
While BCA uppers are a popular choice, many other manufacturers offer AR-15 upper receivers. When considering an alternative, look into features such as: materials, barrel quality, and finish. Compare warranties and customer service policies.
