Length of pull (LOP) is a crucial measurement for firearm fit and shooting comfort. It represents the distance from the trigger face to the center of the buttpad. Getting the LOP right significantly impacts accuracy, recoil management, and overall shooting experience. This guide will detail how to accurately measure your length of pull and explain why it's so important.
Why Length of Pull Matters
Before diving into the measurement process, let's understand why LOP is so vital. An improperly fitted LOP can lead to several problems:
-
Poor Accuracy: If the LOP is too short, the shooter might anticipate recoil, causing flinching and impacting accuracy. Conversely, a LOP that's too long can result in an awkward shooting posture, leading to inconsistent aiming and reduced accuracy.
-
Excessive Recoil: An ill-fitting LOP can exacerbate felt recoil, making the shooting experience uncomfortable and potentially leading to injury.
-
Reduced Comfort and Fatigue: An incorrect LOP forces the shooter into an unnatural posture, leading to fatigue and discomfort, especially during extended shooting sessions.
-
Improper Cheek Weld: A correct LOP ensures a proper cheek weld against the stock, crucial for consistent sight alignment.
Measuring Your Length of Pull: Step-by-Step Guide
Measuring your LOP requires a few simple tools and a methodical approach. Here's how to do it accurately:
1. Gather Your Tools:
- Measuring Tape: A flexible tape measure accurate to at least ⅛ inch (or 1 millimeter). A metal ruler can work, but a tape measure provides more flexibility.
- Firearm: The firearm you intend to use.
- Assistant (Optional): While you can measure yourself, an assistant can make the process easier and more accurate.
2. Assume the Shooting Position:
- Mount the firearm: Shoulder the firearm as if you were preparing to shoot. Ensure a natural and comfortable shooting stance.
- Proper Grip: Maintain a firm but relaxed grip.
3. Locate Measurement Points:
- Trigger Face: Identify the very back of the trigger.
- Buttpad Center: Find the midpoint of the buttpad. This might require some judgment, depending on the buttpad's shape. For curved buttpads, consider the center point of the contact area against your shoulder.
4. Perform the Measurement:
- Extend the Tape Measure: Carefully extend the tape measure from the trigger face to the center of the buttpad, keeping it aligned with the stock.
- Record the Measurement: Record the measurement in inches or centimeters. Be precise.
5. Repeat for Accuracy:
- Multiple Measurements: Repeat the process at least two or three times to ensure consistency. Average your measurements for the most accurate LOP determination.
Adjusting Length of Pull
If your measured LOP isn't ideal, you have a few options:
- Adjustable Stocks: Some firearms feature adjustable stocks allowing easy LOP modification.
- Buttpad Spacers: Adding buttpad spacers can increase the LOP.
- Custom Stock Work: A gunsmith can alter the stock to achieve the perfect LOP. This is the most expensive but often most precise solution.
Conclusion
Knowing your length of pull is paramount for comfortable and accurate shooting. By following these straightforward steps, you can measure your LOP and determine if adjustments are needed. Remember, a correctly fitted firearm contributes significantly to your shooting performance and enjoyment. Don't hesitate to consult a professional gunsmith if you have questions or require assistance in adjusting your firearm's LOP.
