How Rear Support Bags Improve Your Shooting Stability

While front supports like bipods or shooting bags hold most of the rifle’s weight, a rear support bag plays a critical role in fine-tuning your aim and keeping you steady.

The Role of Rear Support Bags in Precision Shooting

No matter the shooting scenario, the right rear support bag helps you achieve steady, repeatable shots.

1. Helps fine-tune elevation adjustments – A rear support bag lets you make fine, controlled adjustments by slightly squeezing or shifting the bag. This gives you precise control over the rifle’s angle, making it easier to zero in on your target without unnecessary movement.
2. Reduces shooter fatigue for longer and more consistent engagements – A well-placed rear bag relieves the strain on your arms and shoulders, allowing you to stay on target longer and shoot more consistently.
3. Increasing rifle stability in different shooting positions – Whether bracing against a barricade or engaging targets from a prone position, a good rear bag stabilizes the rifle and minimizes unwanted movement.

Choosing the Right Rear Support Bag

Finding the right rear support bag depends on your shooting style, terrain, and how much support you need. Whether you’re looking for a compact, lightweight option or a high-volume bag for maximum stability, Cole-TAC offers a variety of solutions to fine-tune your shooting position.

Bitty Bag: Ultra-Compact Option for Lightweight Support

For shooters who need minimal yet effective support, the Bitty Bag is a pocket-sized powerhouse. 

Designed for pistol hunters, competitors, and micro rifle setups, this tiny bag provides just enough elevation adjustment without adding unnecessary bulk. It’s perfect for zeroing optics, fine-tuning your point of aim, or stabilizing your rifle without carrying extra weight.

Boss Bag: Versatile Support with an Adjustable Strap

If you need flexibility in your shooting setup, the Boss Bag delivers. 

Its adjustable strap allows you to customize elevation by tightening or loosening it, making it a versatile choice for different shooting positions. The durable, moisture-resistant fill keeps the bag stable without unnecessary shifting. This makes it a solid option for both rear and front support.

Trap Bag: Trapezoid Shape for Folding Over Obstacles

The Trap Bag takes a unique approach to rifle support. Its trapezoid shape lets you drape it over obstacles while keeping a stable shooting surface. 

Whether resting on a barricade, a log, or the ground, this bag conforms to its surroundings while maintaining a flat, consistent base for your rifle. The Waxed Trap Bag adds increased grip and durability for long-term performance in all conditions.

Woobie Bag: Cylindrical Shape for Elevation Control

The Woobie Bag offers smooth and consistent elevation control thanks to its cylindrical shape and lightweight polymer fill. 

Its ergonomic design makes it easy to grip and maneuver, giving you precise control over rifle angle adjustments. Whether you choose the Standard, Stretch, or Waxed version, the Woobie Bag provides reliable rear support for prone shooting and benchrest setups.

Material and Design Considerations

Choosing the right material and fill for a rear support bag will impact its performance, weight, and durability.

Benefits of Lightweight Polymer Fill vs. Traditional Sand or Bead Filling

The fill type inside a support bag affects its weight, stability, and how it conforms to surfaces.

Lightweight Polymer Fill (Used in Cole-TAC Bags)

1. Provides a perfect balance of firmness and flexibility.
2. Non-absorbent – won’t soak up moisture or degrade over time.
3. Keeps the bag lightweight and easy to carry without sacrificing stability.

Traditional Sand or Bead Filling

1. Heavy and dense, making bags harder to transport.
2. Can absorb moisture, leading to weight fluctuations and potential mold issues.
3. Doesn’t shift as easily, which limits fine-tuned elevation adjustments.

Waxed Canvas vs. Cordura: Durability and Grip Considerations

Both waxed canvas and Cordura offer durability, but each has distinct advantages depending on how and where you shoot.

Waxed Canvas (Available in Woobie and Trap Bags)

1. Superior grip – prevents slippage on smooth surfaces.
2. Water-resistant yet breathable, making it a great choice for outdoor use.
3. Soft, flexible feel while maintaining long-term durability.

Cordura (Standard in most Cole-TAC Bags)

1. Tough abrasion-resistant, making it perfect for harsh environments.
2. Lighter than waxed canvas while still offering strong durability.
3. Withstands repeated use and heavy recoil without fraying or wearing down.

Waxed canvas provides better grip and traction if you’re looking for a bag that stays put on a barricade or rifle stock. If lightweight durability is your priority, Cordura is a solid choice for long-term reliability.

Positioning Techniques for Rear Support Bags

Proper rear bag placement is key to maximizing rifle stability and shot consistency.

Prone Shooting

Prone shooting offers the most stable position for precision shooting, but small adjustments make a big difference.

1. Placement: Position the bag directly under the stock, just behind the rear sling swivel or buttplate. This provides smooth elevation control by simply squeezing or relaxing the bag.
2. Adjustment: Use a bag like the Woobie Bag or Boss Bag to steer elevation with gentle pressure, avoiding the need to adjust the front support. 
3. Hand positioning: Your non-dominant hand should lightly squeeze the bag to control rifle height while keeping your shooting hand relaxed on the trigger.

Barricade Shooting

Shooting from barricades, walls, or uneven surfaces requires adaptable support to counter instability. Rear support bags help absorb recoil, steady your aim, and create a stable shooting surface when bracing against obstacles.

1. On a flat surface: Use a Trap Bag on top of a barricade for a firm rest, letting the bag conform to the surface while keeping your rifle steady.
2. Against a vertical structure: To reduce side-to-side movement, a rear bag can be wedged between your rifle and the structure.
