Understanding the PSA Rock Trigger
Overview of the PSA Rock Trigger
The PSA Rock trigger is a common trigger system found in many of Palmetto State Armory’s AR-15 and other firearm offerings. Its design and function are generally straightforward, emphasizing reliability and ease of use. It’s typically a single-stage trigger, meaning the pull is completed in one continuous motion.
The PSA Rock trigger is usually constructed from steel, with a design that focuses on durability. While the precise materials and manufacturing processes can vary depending on the specific firearm model, the fundamental design philosophy typically prioritizes robustness over refined performance.
One of the primary characteristics of the PSA Rock trigger is its pull weight, which is usually in the range of five to seven pounds. This is a common weight for AR-15 triggers, offering a balance between safety and ease of use. The reset, the point where the trigger returns to its ready position after firing, is generally adequate for most shooters, though it might not be as short or crisp as found on more premium trigger systems. The overall feel of the stock PSA Rock trigger is functional, without any outstanding characteristics. It’s not known for having the smoothest pull, often exhibiting a bit of grit or creep.
Pros and Cons of the Stock PSA Rock Trigger
The biggest advantage of the stock PSA Rock trigger is its cost-effectiveness. PSA firearms are known for their competitive pricing, and the trigger is a significant factor in keeping overall costs down. Availability is also a plus; replacement parts and entire triggers are readily available. The primary function of this trigger is to reliably discharge the firearm, and in that regard, it performs well.
However, the stock PSA Rock trigger has its downsides. The heavier pull weight can be challenging for some shooters, potentially leading to involuntary movement and decreased accuracy. The gritty feel and less-crisp break are further disadvantages, making it less than ideal for precision shooting. The longer reset might slow down follow-up shots for those seeking rapid firing.
Why Consider an Upgrade?
The motivation to improve a trigger system often stems from a desire to elevate the overall shooting experience. Shooters may seek improved accuracy, which can be achieved with a lighter, crisper trigger. A lighter pull weight reduces the likelihood of jerking the trigger, which throws off the shot. A clean break minimizes any unexpected movement as the round is fired.
Faster follow-up shots is another key driver for an upgrade. A shorter reset allows the shooter to quickly re-engage the trigger and fire again, crucial in dynamic shooting scenarios. Shooters who participate in competition might seek the performance advantage that a superior trigger can provide.
Beyond performance enhancements, an upgrade can simply make shooting more enjoyable. A smoother, more responsive trigger can make the shooting experience far more satisfying. By upgrading the PSA Rock trigger, owners are effectively addressing the very common complaints and potential shortfalls of the original design.
Types of PSA Rock Trigger Upgrades
Drop-in Triggers
One of the most popular trigger upgrades is the use of drop-in triggers. These are complete trigger assemblies that simply drop into the lower receiver of the firearm, replacing the entire original trigger group. Drop-in triggers come in various configurations, with varying pull weights, reset lengths, and overall feel. They often have a very clean break, a short reset, and a lighter pull weight, which makes the shooting experience more pleasant and accurate.
Many reputable companies manufacture drop-in triggers compatible with PSA Rock-equipped firearms. The installation is usually very straightforward and can be performed by the average firearm owner with minimal tools. Simply removing the original trigger components and inserting the new one is usually all that is involved. The main advantage of this type of upgrade is its ease of installation and significant improvement in trigger performance. Disadvantages might include a higher cost compared to other upgrade options.
Trigger Spring Kits
Another option is to replace the trigger springs. Trigger spring kits provide a more economical way to modify the trigger pull weight. The kits typically include a main hammer spring and trigger spring, which can be swapped out with the factory springs. Replacing the springs can make the trigger lighter and improve its feel. However, this option offers a more modest improvement compared to a drop-in trigger and requires more time and skill to install.
Safety is always paramount when working on firearms. The change in trigger pull weight might have unforeseen consequences, so safety is crucial. When switching out springs, users should be cautious, carefully test the firearm after the upgrade, and ensure it functions safely.
Polishing the Trigger Components
For those who are mechanically inclined, the polishing of trigger components is another upgrade option. This involves disassembling the trigger group and polishing the contact surfaces, reducing friction, and improving the smoothness of the trigger pull. This modification can eliminate grit, reducing the feel of creep, making the break crisper. Polishing requires more time and effort and some degree of skill, and it may not be as effective as a full trigger replacement.
Evaluating the Upgrade Process
Tools and Materials Needed
Upgrading the trigger is a relatively straightforward process, but it’s important to be prepared. The tools and materials required depend on the type of upgrade being performed. Drop-in trigger upgrades generally require little more than a few punches, a hammer, and possibly a small screwdriver. A trigger spring kit will require similar tools, while polishing the trigger components calls for a selection of fine-grit polishing compounds, a polishing wheel or cloth, and a method to disassemble the trigger group safely.
Always use proper safety equipment. Eye protection is an absolute necessity, and gloves are also recommended.
Step-by-step Installation Guide
The installation process varies according to the chosen upgrade. Drop-in triggers usually have simple instructions, often requiring a few pins to be removed and replaced. Spring kit installation involves replacing specific springs within the original trigger group, and polishing involves careful disassembly, polishing, and reassembly of the trigger components.
Safety Precautions
Firearm safety is not just important, it is paramount. Always ensure the firearm is unloaded before beginning any upgrade work. After installation, thoroughly test the firearm for proper function. Perform a function check to ensure the trigger reliably resets and that the safety mechanisms work. A drop test should also be performed.
Performance and Comparison
Measuring Trigger Performance (Before and After)
Before and after any trigger upgrade, objectively measuring trigger performance is essential. The pull weight can be measured using a trigger pull gauge, a simple tool that accurately measures the force required to actuate the trigger.
Comparing Upgrade Types
Assessing the smoothness of the trigger pull is a subjective process, but the before and after feeling should be compared. How the trigger feels will be greatly affected, so a smooth pull with a clean break is what you are looking for. The break, where the trigger releases the hammer, should be clean and crisp, without any unexpected creep or grit. The reset, the distance the trigger travels to re-engage, should be short and positive.
User Feedback and Reviews
Comparing the performance of different trigger upgrades can reveal their advantages and disadvantages. Drop-in triggers generally offer the most significant performance gains, often providing a much lighter pull, a crisper break, and a shorter reset. Spring kits offer an improvement at a lower cost, but with a more modest result. Polishing, which requires more skill and effort, is less likely to provide as a dramatic of a change.
User feedback and reviews can provide valuable insights into the effectiveness of a trigger upgrade. Many online forums, websites, and videos feature reviews of various triggers and modification options. Common themes include the level of improvement and ease of installation.
