If a short setup doesn’t fail because of length but because of optics, chamber lever, and loose accessories during transport, no soft case without internal control helps.
The AIM 40 is the compact Tactical Drag Bag for carbines and shorter long guns up to 99 cm. It’s designed for leading hunting and range setups but requires that the entire transport profile in this 40 size really remains pressure-free.

What this 40 size is built for
AIM does not position the 40 as a universal rifle bag for as many lengths as possible but as a compact drag bag for leading systems. The manufacturer specifies carbines and shorter long guns up to 99 cm. That’s exactly where the benefit lies: less unnecessary interior space, more controlled fixation, and a bag that doesn’t feel longer than necessary on a tight stand, in the vehicle, or on short paths to the stand.
The purchase limit is therefore not only reached above 99 cm. Even below that, a setup can be unsuitable if tall adjustment turrets, a wide chamber lever, a long muzzle component, or a side-mounted bipod put pressure on the internal contour. With this bag, not only the total length must fit but the entire transport profile.
What makes the difference in the main compartment
The main compartment is Cordura-lined and works with three adjustable weapon straps plus a reinforced stock support. This means the rifle is not just laid in but fixed at load-bearing points. This is crucial, especially with a compact bag: if the system shifts inside, even thick padding helps significantly less.
Additionally, there is padded protection along the main zipper so that the weapon and optics don’t rub directly against the zipper edge. The zipper opens on three sides, and side clips additionally secure the compartment when closed. Protective flaps over the zippers keep rain, sand, and dust better out of the direct path.
Carrying, accessories, and weather limit
The AIM 40 can be carried in three ways: as a backpack with padded shoulder straps plus hip and chest strap, by the central handle for horizontal transport, and by the rear handle for classic drag-bag or vertical handling in tight passages. Unneeded shoulder straps can be stored in a zipper pocket. This helps when the bag shouldn’t hang on loose straps in the vehicle, closet, or tight stand.
Two large outer pockets, additional webbing loops, an internal cleaning rod sleeve, and the drag hood for the muzzle area separate accessories sensibly from the main compartment. For 100% waterproof, AIM explicitly recommends a separate small rain cover. The bag itself is robust and water-resistant but not the honest complete solution for continuous rain without an additional cover.

Important tip
Safety notice: AIM explicitly warns against buying or using this bag if you wear pacemakers, implantable cardioverter-defibrillators, or other implanted medical devices. The reason is the magnetic chest strap.
Our assessment
The strongest reason to buy is not simply the short external length, but the precise fit for compact rifles that need to be securely fixed and transported with mounted optics. If your setup really belongs in this 40-class, less empty space is often a bigger advantage than a precautionarily oversized bag.
The most common mistake is measuring only the bare weapon length. Ignoring optic height, muzzle component, chamber lever, and the actual transport position leads to buying a bag that fits on paper but still pinches in everyday use. Especially with a compact Drag Bag, honest measuring is more important than model number logic.
Buy or not buy?
Buy if: your carbine or shorter long gun remains fully transport-ready within 99 cm, you want a firm internal fixation, and you’re looking for a compact Drag Bag for range or hunting that doesn’t carry unnecessary empty space.
Don’t buy if: your setup only fits under tension due to length or build height, you need more reserve for longer systems anyway, or you expect full weather protection immediately without a separate cover.
Trainer tip

Don’t just measure length, but the widest transport contour: Place the unloaded rifle exactly in the position it will later be packed. Measure total length, optic height, and the widest point at the chamber lever, chassis, or bipod. With compact bags, it’s almost never the last length reserve that’s the problem, but lateral pressure at a single spot.
Three practical user tips

First set stock and system, then tighten straps: The reinforced stock holder should determine the rear position. Those who first tighten the fore-end quickly pull the rifle crooked into the bag and lose the actual internal control.

Don’t use outer pockets as dump pockets: Heavy small parts belong close to the carrying point and as evenly distributed as possible. A one-sided loaded outer pocket twists the bag on the back and unnecessarily stresses handles, seams, and shoulder strap.

After rain, open completely and dry: Water-resistant doesn’t mean moisture inside disappears. Open main compartment and outer pockets fully so padding, Drag Hood, and zipper areas can dry thoroughly.
System logic and matching products
If the 40-class gets too tight at the real transport contour, the AIM 45 rifle bag within the same series is the next comparison level. If you need noticeably more reserve for longer setups or additional accessories, check out the AIM 50 rifle bag and the AIM 55 rifle bag. For the question of space, the biggest bag is not automatically the best, but the smallest size in which your complete setup lies pressure-free.

Matching alternatives in the system:

AIM 45 rifle bag – if your setup measured cleanly at the 40 limit becomes slightly too tight.

AIM 50 rifle bag – for more bag reserve within the same Tactical Drag Bag family.

AIM 55 rifle bag – if you clearly fall out of the compact 40 class.

FAQ
What firearm length fits in the AIM 40? AIM specifies a maximum of 99 cm. The complete ready-to-transport setup is measured, not just the bare system without optic or muzzle device. Is the AIM 40 intended for standard long guns or rather for compact setups? The product page clearly assigns it to carbines and shorter long guns. This is exactly the advantage of this bag: less empty space and more controlled fixation. Does a mounted optic remain in the bag? Yes, as long as height and width fit pressure-free into the inner contour. The padded protection along the main zipper is designed exactly for optic and firearm. Is the bag completely waterproof without an additional cover? No. AIM explicitly refers to a separate small raincover for 100% waterproofing. The bag itself is water-resistant but not described as a sole solution for prolonged rain. How is the rifle fixed in the main compartment? Via three adjustable gun slings, a reinforced stock mount, and the compact inner contour. The system is meant to be held at load-bearing points and not move around in the main compartment. What carrying styles does the AIM 40 offer? It can be carried as a backpack, by the central handle horizontally, and by the rear handle for classic drag-bag or vertical handling.
