ABR™ Rider & Rear Bag Selection Guide

Choosing the right lower rider and rear shooting bag helps you get the best performance from your Adjustable Bag Rider.

Your ideal setup depends on the lower rider you select—V, ELR, or SQR—along with your shooting application, desired bag height, and the type of rear support you prefer.

Use this guide to compare ABR™ rider profiles, determine the proper rear bag ear spacing, and choose a shooting bag that provides stable support while maintaining easy access to the thumb wheel.

I Already Have A Leather Bag.

Which Lower Rider Should I Choose?

  • V Rider

    Best for standard two-stitch rear bags

    • Fits a standard two-stitch bag

    • Approximately 3/8" ear spacing

    • V-shaped lower profile

    • Good choice if you already use a compatible traditional rear bag

    Best if: You want to use your ABR™ with a standard two-stitch shooting bag.

  • ELR Rider

    Wider platform for greater rear support

    • .850" wide

    • .5" tall

    • Approximately 5/8" optimum ear spacing

    • Works well with ELR-style bag ears

    • Wider footprint works well with softer rear bags

    Best if: You want a wider contact surface or shoot ELR/long-range configurations.

  • SQR Rider

    • .850" wide

    • .825" tall

    • Approximately 5/8" optimum ear spacing

    • Similar width to the ELR rider with a taller profile

    Best if: You want a wider contact surface or shoot ELR/long-range configurations.

A Note About Your Bag’s Ear Spacing

If your bag has wider ear spacing than the available rider(s), a stripe of leather, for example, can be placed across the ear tops and the ABR™ lowered into place. The additional leather will fill the space so the rider has no play right to left.

Which rear bag attributes work best with an ABR™?

Your Existing Rear Bag May Work.

You don't necessarily need a new shooting bag to use an Adjustable Bag Rider. The below attributes are recommended for a secure fit.

  • Leather bag tightly packed with sand

  • Bunny ears

  • Proper ear spacing (tight on rider)

  • Proper height 

  • Rounded back (for bench shooting)

  • Smaller bag that is easier to move a small amount

  • 3M Slick Silver recommended

Round Back ABR™ Protektor Model Bag (tall version) with Bunny Ears and Slick Silver.

For the best fit:

V Rider → approximately 3/8" ear spacing

ELR Rider → approximately 5/8" ear spacing

SQR Rider → approximately 5/8" ear spacing

The fit should be snug. Any space between a heavy leather bag's ears and the rider can negatively affect tracking and create horizontal groups.

Protektor Model ABR™ Rear Shooting Bags

Looking for a Traditional Leather Rear Bag?

Long Shot Precision has worked closely with Protektor Model to develop the ABR™ Rear Shooting Bags, specifically designed to work with an Adjustable Bag Rider.

These collaborative bags are designed to maximize thumb-wheel clearance between the front of the bag ears while providing a consistent, stable interface with the ABR™. The shorter ears allow the rider to extend over the back of the bag, helping maintain consistent recoil and tracking.

Choose from Bunny Ear or the even lower-profile ELR Ear configuration, depending on your setup and preferred clearance.

The rounded back also provides additional chest clearance when shooting from a bench, reducing the chance of the corner of the bag contacting your ribs as you lean forward to get behind the scope.

Designed specifically for ABR™ use. Built for clearance, consistency, and control.

ABR™ Protektor Model Small ELR Bag.

Round Back ABR™ Protektor Model Bag (tall version) with Bunny Ears and Slick Silver.

Small ELR: 1.5" between ears and ground

Short Round Back: 2¾" from bottom of ears to ground

Tall Round Back: 3¾" from bottom of ears to ground

Long Shot Precision recommends purchasing your ABR™ first, measuring your required bag height, and providing Protektor with your ABR™ configuration and measurements when ordering.

Rear Bag Features That Matter

What Should You Look for in an ABR™ Rear Bag?

Round Back ABR™ Protektor Model Bag (tall version).

Low Ears
Help maintain access to the thumb wheel at all times.

Short Ears
This allows the rider to hang over the back - for consistent recoil.

Correct Ear Spacing
The rider should fit snugly between the ears for consistent tracking.

Proper Height
Choose the lowest practical bag that works with your shooting setup. Shims can be added.

Rounded Back (for Bench shooting)
Having a rounded back bag provides additional chest clearance when shooting from a bench as leaning forward to get on the scope may cause a regular square bag to hit your ribs.

Long Shot Precision specifically recommends using the smallest, lightest bag practical for your setup, because a smaller bag is easier to reposition the reticle back into alignment.

Rear Bag & Rider FAQ

  • What's the difference between the V and ELR rider?

    The V Rider features a V-shaped bottom designed to work with a standard two-stitch rear shooting bag and approximately 3/8" ear spacing.

    The ELR Rider has a wider, flat bottom measuring approximately .850" wide by .5" tall and works best with approximately 5/8" ear spacing. Its wider footprint provides additional contact area with rear bag and is the most popular choice for long-range and ELR shooting setups.

  • What is the best ear spacing for an ABR™?

    Recommended ear spacing depends on your lower rider:

    • V Rider: approximately 3/8"

    • ELR Rider: approximately 5/8"

    • SQR Rider: approximately 5/8"

    A snug fit between the rider and bag ears is important. Any side-to-side space, particularly with a firm leather rear bag, can create horizontal groups due to inconsistent tracking during recoil.

  • Do I need a bag with bunny ears?

    No, but bunny ears or lower ELR-style ears are recommended for many Adjustable Bag Rider setups because their lower profile provides easier access to the thumb wheel at all times.

    The most important considerations are proper rider fit, stability, correct bag height, and maintaining access to the adjustment mechanism.

  • Can I use a squeeze bag or sand sock with an ABR™?

    Yes. An Adjustable Bag Rider can be used with different styles of rear support, including some squeeze bags and sand socks. Fill migration causes and squeezing inconsistencies create vertical dispersion.

    However, a properly fitted rear shooting bag with ears will provide a more consistent interface for the rider and will improve stability and consistent tracking. If precision and repeatability are your priorities, choose a bag designed or fitted specifically for your ABR™ configuration.

  • Should I buy my ABR™ or rear bag first?

    Choose and install your Adjustable Bag Rider first.

    Once the ABR™ is installed, extend it approximately halfway at your favorite spot and install shims under the rider until you are comfortable behind the scope. Measure the shims or from the shooting surface to the bottom of the rider. Once you have this measurement you can select a bag. This is especially important when ordering custom rear shooting bag. 

    If your measurement does not match the standard height bag we suggest ordering a bag lower than needed because a shim / space can be added.  Or the shim can be left out to shoot uphill.

  • Once set up, what steps should be done prior to the first shot?

    If you are using a leather bag or softer bag and will be using the thumb wheel for vertical adjustment - tamp down on the top of the recoil plate with your fist to settle the sand or fill below the rider. If your first shot(s) are higher then you did not tamp enough. Make note of how many times you tamp down for future use.

    Softer bags might be able to be folded in half to reduce fill migration and tighten the fill.

  • What's the difference between the LSP Small and Large Bag?

    The LSP Small Bag is a compact, lightweight option designed for portability and versatility. It provides approximately 2.25" of settled height and can also be stood on end for approximately 3" of height. Its smaller size makes it well suited for hunting, PRS, field shooting, and shooters who want a lightweight rear support.

    The LSP Large Bag provides a larger, more stable footprint and was developed with Extreme and Ultra Long Range shooters and heavier rifles in mind. Its flat bottom helps reduce rolling during recoil, while an adjustable fill port allows the shooter to customize the amount of fill.

    Both bags feature surfaces designed to provide grip on one side and smoother ABR™ movement on the other.
