The Rock River Arms Varmint is a popular choice for precision shooting, and a significant part of its accuracy potential hinges on a crisp, reliable trigger. This guide delves into everything you need to know about the Rock River Varmint trigger, from factory specifications and potential upgrades to troubleshooting and adjustment techniques. Whether you're a seasoned marksman or a new owner, understanding your trigger is crucial for maximizing your shooting accuracy and overall experience.
Understanding the Factory Trigger
Rock River Arms (RRA) equips their Varmint rifles with a two-stage trigger, designed for a balance between a clean break and a manageable pull weight. The factory trigger is generally considered adequate for many shooters, offering a reasonably consistent pull. However, some users find the pull weight too heavy or the travel distance too long for precision shooting applications. This often prompts upgrades or adjustments.
Factory Trigger Specifications (Approximate):
- Pull Weight: Typically ranges from 4 to 6 pounds. This can vary slightly depending on the rifle's manufacturing date and specific components.
- Stages: Two-stage design with a distinct take-up followed by a clean break.
- Creep: Minimal creep is generally present in a factory-fresh trigger, but this can increase over time with use and wear.
Upgrading Your Rock River Varmint Trigger
Many shooters opt to upgrade their RRA Varmint trigger for a lighter, crisper, and more predictable pull. Several reputable aftermarket trigger brands offer drop-in replacements designed for the AR-15 platform, making installation relatively straightforward.
Popular Aftermarket Trigger Options:
While specific recommendations are outside the scope of this article to avoid the appearance of endorsements, researching reputable brands known for their high-quality AR-15 triggers will yield many suitable options. Consider triggers known for their adjustability, allowing fine-tuning of pull weight and overtravel. Always prioritize safety and ensure compatibility with your specific RRA Varmint model.
Adjusting Your Factory Trigger (Proceed with Caution)
Adjusting your factory trigger can improve its performance, but it's crucial to approach this task with caution. Improper adjustment can compromise the rifle's safety and reliability. If you lack experience, it's strongly recommended to seek the assistance of a qualified gunsmith.
Potential Adjustments (Advanced Users Only):
- Overtravel Adjustment: Some RRA Varmint triggers may allow for limited overtravel adjustment. This reduces the distance the trigger travels after the shot breaks.
- Pre-travel Adjustment (Limited): The pre-travel (or take-up) might have minimal adjustability in certain models. Excessive modification in this area could negatively impact trigger safety.
Troubleshooting Common Issues
- Heavy Trigger Pull: A heavy pull can be addressed through an upgrade to an aftermarket trigger or, with caution and expertise, through adjustments to the factory trigger.
- Trigger Creep: Slight creep is normal but excessive creep indicates the need for professional attention or an upgrade.
- Trigger Drag: Drag usually signifies a problem requiring attention, possibly a cleaning or parts replacement.
Maintaining Your Trigger
Regular cleaning and lubrication of your trigger group are essential for maintaining its smooth operation and reliability. Use a high-quality gun lubricant specifically designed for firearms and follow the manufacturer's instructions for cleaning and maintenance.
Conclusion
The Rock River Arms Varmint trigger plays a pivotal role in the rifle's accuracy and overall shooting experience. While the factory trigger is functional, many shooters find upgrades or minor adjustments beneficial for enhanced performance. However, remember that safety should always be the top priority. If you are unsure about any modification process, consult a qualified gunsmith. Proper maintenance will help ensure your trigger remains reliable and contributes to your success on the range.
