The PSA (Palmetto State Armory) lower receiver is a popular choice among AR-15 builders and enthusiasts due to its affordability and generally reliable performance. However, many users find the stock trigger to be less than ideal, often exhibiting grit, creep, and a heavy pull weight. This is where the PSA Rock Trigger Upgrade comes in. This upgrade significantly improves the shooting experience, making the rifle more accurate and enjoyable to shoot. This comprehensive guide will delve into everything you need to know about upgrading your PSA rifle with a Rock Trigger.
Why Upgrade Your PSA Trigger?
The factory trigger in most PSA rifles, while functional, often leaves much to be desired for serious shooters or those seeking enhanced performance. Common complaints include:
- Heavy pull weight: This can lead to fatigue during extended shooting sessions and reduces accuracy.
- Grit and creep: These imperfections in the trigger's movement translate to inconsistent shot breaks and reduced precision.
- Long reset: A lengthy trigger reset requires more time and effort between shots, slowing down the shooter's cadence.
Upgrading to a better trigger addresses these issues, providing a smoother, lighter, and more precise trigger pull. This translates to improved accuracy, faster target acquisition, and a more enjoyable shooting experience. The PSA Rock Trigger is a popular and cost-effective option for this upgrade.
Understanding the PSA Rock Trigger
The PSA Rock Trigger is a drop-in replacement for the standard mil-spec trigger group. It's designed to provide a significant improvement in trigger feel without requiring extensive gunsmithing skills. Key features often include:
- Reduced pull weight: Generally lighter than the factory trigger, often around 4-5 lbs. (This can vary slightly depending on the specific model and installation).
- Crisp break: A clean and predictable trigger break contributes to improved accuracy.
- Shorter reset: Allows for quicker follow-up shots, improving overall shooting speed.
- Enhanced reliability: While the factory trigger is generally reliable, the Rock Trigger often boasts improved consistency and durability.
It's important to note that while the Rock Trigger is considered a significant improvement over the factory trigger, it's not a match-grade trigger. For competitive shooting or extreme precision requirements, a higher-end trigger may be necessary.
