AIM FSX-42 Reverse Folding Stock Bag

AIM FSX-42 Reverse Folding Stock Bag

Folding stocks are often seen on military grade weapons since a collapsible stock makes the weapon more compact for storage and transport. More and more tactical rifles are being fitted with folding stocks too. Until now, a dedicated folding stock bag has been very hard to find. Our specialist Folding Stock Bags® have been developed in conjunction with leading rifle manufacturers to offer a unique and secure way of transporting the re-configured rifle shape with wider stock. Aim Field Sports® has developed separate models for right and left folding stocks (see below).

The FSX-42 has been designed for folding stocks that fold left away from the bolt. Please refer to the AIM® FS-42 pages if your rifle folds in the opposite way. This bag will take a rifle up to a maximum folded length of 40½ inches (103 centimetres). To make it 100% waterproof, combine with a small raincover.

Product Description

AIM® FSX-42 Folding Stock Bag® – unique design


  • The flared and deep rifle butt pocket inside the bag is fully adjustable to hug the folded stock within the bag.
  • An additional reinforced support beneath the butt pocket provides extra security for the weapon.
  • Four fully-adjustable weapon straps can be positioned and tightened according to your choice to secure the barrel in position.
  • An integral cleaning rod sleeve runs along the spine of this bag.
  • A padded rim runs along the inside of the zip ensuring that the weapon and scope are protected from the opening/closing zip. The large rifle compartment has a zip that opens around three sides for greater access.
  • The bag is as compact as an AIM 40 when empty.
  • All zips have flaps to cover them against ingress of rain.
  • Externally two webbing compression straps on the lower section of the bag allow the folded stock to be further secured in position.
  • Two large external utility pockets with elasticated straps inside to hold accessories in place.
  • Additional webbing loops on pockets for attaching more gear.
  • The bag can be carried in three ways offering greater flexibility in use:
    • as a rucksack. Padded straps with waist and sternum belts for stability in motion. Strong metal carabiners on the shoulder straps offer further strength to the bag. The straps can be neatly packed away, tucked inside a zipped compartment when not in use.
    • as a grip bag. A webbing handle is positioned midway along the bag, providing a well-balanced option for moving it horizontally.
    • via the webbing handle on the back of the bag (above the rucksack strap compartment). The bag can be dragged along the ground in classic drag bag mode. Alternatively, you can hold the bag securely vertically upright for moving along narrow corridors.
