Understanding and adjusting your firearm's length of pull (LOP) is crucial for comfortable shooting and improved accuracy. A poorly fitted LOP can lead to discomfort, poor aim, and ultimately, missed shots. This comprehensive guide will walk you through how to determine the ideal length of pull for your specific needs, covering various measurement techniques and considerations. Knowing your perfect length of pull is a vital step in optimizing your shooting experience.
Understanding Length of Pull
The length of pull refers to the distance between the trigger face and the back of the stock (where your shoulder meets the gun). It's a critical dimension impacting shooting posture, recoil management, and overall accuracy. An incorrect LOP can result in:
- Poor Cheek Weld: An improperly fitted LOP can force you to strain your neck or cheek to achieve a proper sight picture, leading to fatigue and inconsistent aim.
- Inconsistent Recoil Management: A too-long LOP can push the gun into your shoulder too forcefully, causing flinching and poor follow-up shots. A too-short LOP can lead to the gun "kicking" upward and out of your shoulder pocket.
- Reduced Accuracy: The cumulative effect of discomfort, poor posture, and inconsistent recoil management directly impacts accuracy.
Finding the right LOP is a personalized process, with no single "correct" measurement. It's dependent on your individual body type, build, and shooting style.
Measuring Your Current Length of Pull
Before determining your ideal LOP, measure your current firearm's LOP. You'll need a ruler or tape measure.
- Position the Gun: Place the firearm on a flat surface.
- Measure from Trigger: Measure the distance from the center of the trigger to the back of the buttpad, along the line of the stock.
- Record the Measurement: Note this measurement precisely. This is your baseline for comparison.
Methods for Determining Ideal Length of Pull
Several methods can help determine your optimal LOP. These often involve a combination of measurement and subjective feel.
Method 1: The Arm-Extended Method
This is a quick and simple method, but it might not be as precise as other methods.
- Stand with Arms Extended: Stand upright with your arms extended fully forward.
- Measure from Fingertips: Measure the distance from your fingertips to the crease of your elbow.
- Adjust for LOP: Subtract approximately 1-1.5 inches (2.5-3.8 cm) from this measurement. This adjusted figure provides a starting point for your ideal LOP. This method is based on the idea that your arm length roughly correlates to the proper reach for a firearm.
Method 2: The Body Measurement Method
This method involves measuring your body to estimate the ideal LOP.
- Measure Shoulder-to-Hand Length: Measure from your shoulder to your hand, with your hand loosely grasping a small object, simulating the grip on a firearm.
- Add for Stock Shape: Add an inch or more to account for stock type and shooting style. Straight stocks generally require less, while monte carlo stocks (those with a raised comb) require more.
- Consider Stock Type: Different types of stocks (e.g. pistol grip, straight stock) can influence the ideal LOP.
Method 3: Trial and Error (with a Friend or Professional)
This method allows for subjective assessment of comfort and fit. It’s ideal if you have access to firearms with adjustable LOP or a gunsmith.
- Try Different LOPs: Shoot firearms with slightly different LOPs.
- Note Comfort and Accuracy: Pay attention to your comfort level and accuracy.
- Iterate and Refine: Adjust the LOP until you find the optimal balance of comfort and accuracy.
Adjusting Your Length of Pull
If your current firearm's LOP isn't ideal, you can adjust it through several methods:
- Buttpad Adjustment: Some firearms have adjustable buttpads that allow for fine-tuning the LOP.
- Adding or Removing Buttpad Material: A gunsmith can add or remove material from the buttpad to modify the LOP.
- Replacing the Buttpad: You can replace the existing buttpad with one of a different thickness.
Considering Other Factors
Beyond LOP, other factors influence your shooting comfort and accuracy:
- Drop at Comb: The vertical distance from the top of the comb (where your cheek rests) to the center of the bore.
- Drop at Heel: The vertical distance from the top of the heel of the buttstock to the center of the bore.
- Cast: The horizontal offset of the comb.
- Recoil Pad Material: A softer recoil pad can help mitigate recoil.
A properly fitted firearm should align your eye, sights, and the target naturally with minimal strain.
Case Study: The Impact of Improper LOP
A competitive shooter I worked with consistently struggled with accuracy despite years of practice. After evaluating his setup, we discovered he had an LOP that was too long for his build. This was causing him to shift his posture and strain his shoulder, impacting his aim and consistency. After adjusting the LOP with a new buttpad, his accuracy improved dramatically.
Conclusion
Determining your ideal length of pull is an important step in enhancing your shooting experience. While there’s no magic number, using the methods outlined above, combined with personal testing and feedback, will greatly improve your comfort, accuracy, and overall shooting performance. Remember to carefully consider all factors – body dimensions, stock type, and shooting style – to optimize your firearm's fit for maximum effectiveness. Don't hesitate to consult with a professional gunsmith for personalized assistance. Remember: safety first! Always handle firearms responsibly.
