The length of pull (LOP) is a critical, often overlooked, aspect of firearm fit and function. Getting the LOP right significantly impacts shooting comfort, accuracy, and overall safety. This comprehensive guide will delve into what LOP is, how to measure it, why it matters, and how to adjust it for optimal performance.
What is Length of Pull?
Length of pull refers to the distance between the trigger face and the rearmost point of the buttstock where it meets the shooter's shoulder. It's a crucial dimension that dictates how comfortably and effectively a shooter can mount and control their firearm. An incorrect LOP can lead to a variety of problems, from poor accuracy and discomfort to even dangerous handling issues.
Why is Length of Pull Important?
Proper LOP is essential for several reasons:
-
Accuracy: An improper LOP can force the shooter into awkward postures, affecting their ability to maintain a consistent and stable shooting stance. This leads to inconsistent shot placement and reduced accuracy.
-
Comfort: A too-long or too-short LOP can cause discomfort and fatigue, especially during extended shooting sessions. This can negatively impact the shooter's concentration and overall performance.
-
Safety: An incorrectly fitted firearm can increase the risk of accidental discharge. For example, a too-short LOP might force the shooter's finger onto the trigger unintentionally. Conversely, a too-long LOP can lead to a poor cheek weld, compromising the sight picture and potentially causing the weapon to shift during recoil.
-
Recoil Management: The proper LOP helps distribute recoil effectively, minimizing felt recoil and improving control, particularly with higher-caliber firearms.
How to Measure Length of Pull
Measuring your LOP is a straightforward process that requires only a ruler or tape measure. Here's how:
-
Shoulder the firearm: Assume your normal shooting stance, ensuring the firearm is mounted naturally.
-
Measure the distance: Using a ruler or tape measure, carefully measure the distance from the trigger face to the point where the buttstock meets your shoulder. Be sure to measure along the axis of the firearm, not diagonally.
-
Record the measurement: Note the measurement in inches or centimeters. This is your current LOP.
Adjusting Length of Pull
If your current LOP isn't ideal, there are several ways to adjust it:
-
Adding or Removing Buttpads: Many firearms allow for the addition or removal of buttpads to adjust the LOP. These are readily available in various thicknesses and materials.
-
Replacing the Stock: For a more significant adjustment, replacing the entire stock is an option. This requires more investment but offers a wider range of LOP adjustments. Consider seeking advice from a gunsmith.
-
Using a Recoil Pad Spacer: These are specifically designed to increase LOP by adding a layer between the stock and recoil pad.
Determining the Optimal Length of Pull
The optimal LOP varies from person to person depending on factors such as body size, arm length, and shooting style. However, some general guidelines exist:
-
Average LOP: A generally accepted average LOP for adults is between 13.5 and 14.5 inches. However, this is merely a starting point.
-
Personal Fit: The best way to determine your optimal LOP is through experimentation and personal preference. Start with the average and adjust based on comfort and accuracy.
-
Professional Assistance: Consider seeking professional assistance from a firearms instructor or gunsmith who can help determine your optimal LOP and guide you on adjustment options.
Conclusion
Length of pull is a frequently overlooked but critically important aspect of firearm fit. By understanding how to measure and adjust your LOP, you can significantly improve your shooting comfort, accuracy, and overall safety. Remember that finding the right LOP is a personalized process; take the time to experiment and find the perfect fit for your individual needs.
