Does the Quake A04931 shooting bag come pre-filled, and what is the best fill material to use?

The Quake A04931 model is supplied as an unfilled fabric shell weighing under 200 g to keep freight costs low. When filled with materials like plastic poly pellets, sand, or spever beads, the bag reaches an optimal operating weight of approximately 3.45 to 3.5 lbs (1.56 to 1.59 kg) for stable recoil management.

How does the briar-proof fabric hold up in harsh Australian scrub and wet environments?

Engineered for rugged field conditions, the outer shell is constructed from heavy-duty, water-resistant, and briar-proof fabric designed to resist punctures, tears from thorns, and abrasive ground cover. This makes it exceptionally durable when zeroing firearms or hunting in dense, scrub-heavy Australian outback environments where standard nylon bags might fail.

Can this triangular bag be used for dynamic barricade shooting or only for standard benchrest use?

While its compact 9.0 in L x 5.0 in W x 5.0 in H triangular profile provides reliable passive elevation and stock stability for benchrest zeroing and prone hunting, it is best suited for stationary use. For dynamic barricade or PRS match shooting requiring superior surface moulding across fences and window frames, larger wedge or pinch bags are generally recommended instead.

Shooting Rear Bag - Quake A04931

The Quake A04931 Medium Triangular Shooting Rear Bag provides passive elevation adjustment and buttstock stability for precision target shooting, firearm zeroing, and field hunting. Built from water-resistant, briar-proof fabric, this triangular rear support resists punctures, thorns, tears, and abrasive scrub in wet and rough field environments. It offers universal firearm compatibility, supporting rifle buttstocks, shotgun stocks, chassis toe rests, or small forends across all standard sporting, hunting, and tactical calibres.

Key Features

Triangular Form Factor: Delivers variable elevation planes depending on which face is placed down, allowing micro-elevation adjustments under the buttstock without mechanical rests.
Briar-Proof Outer Fabric: Constructed from heavy-duty, puncture-resistant material designed to withstand thorns, rough ground cover, and moisture.
Passive Mechanical Support: Non-powered rear rest requiring no batteries or electrical power, suitable for short-range 25–100 m zeroing through to extended long-range target distances.
Universal Firearm Interface: Compatible with all standard calibres from .22 LR to heavy magnum hunting cartridges.

Who is the Quake Medium Triangular Shooting Rear Bag for?

Precision rifle shooters zeroing firearms in rugged terrain — requires a triangular shooting rear bag measuring 9.0 in L × 5.0 in W × 5.0 in H that offers distinct elevation planes for micro-adjustments on uneven ground cover.
Hunters operating in wet or thorny environments — benefits from a 3.45 lbs to 3.5 lbs rear bag built with briar-proof, water-resistant outer fabric that resists thorn punctures and ground moisture while anchoring the buttstock.

Less suitable for: Dynamic barricade and PRS match shooting where positional flexibility over fence rails and window frames requires larger wedge or pinch bags for superior surface moulding; or weight-restricted backcountry hunting where a 1.56 kg filled bag exceeds packing limits, making dedicated ultralight micro-pillows a more practical alternative.
