Quick answer

Measure your rifle's overall length from muzzle to buttstock with the scope attached, then add 2–3 inches of clearance. Match that to a bag's internal length, and check that the scope height fits within the bag's internal height.

Why scope height matters as much as length

A rifle that fits in length can still be a tight squeeze if the scope sits high. Most gun bags list internal height as well as length. The Endeavor bags, for example, have a 235mm (9-inch) internal height, which comfortably accommodates most scoped rifles. If you have a large objective lens or an extra-high mounting ring, double-check that number.

Trade-off: one bag for multiple rifles

If you own several rifles of different lengths, a single bag that fits the longest one will leave shorter rifles rattling around inside. Extra padding or a second bag for the shorter rifle solves the movement problem. The Endeavor GB53 (1280mm internal length) works for a full-size hunting rifle, while the GB44 (1050mm) is a better match for a compact air rifle or carbine.

How to measure and choose your rifle bag

  1. Measure overall length with scope attached: Lay the rifle flat on a table. Measure from the tip of the muzzle to the end of the buttstock. If the scope extends past the receiver, include its full length in the measurement. Common mistake: measuring only the barrel or the action, which ignores the scope's overhang.
  2. Add 2–3 inches (50–75mm) of clearance: A bag that exactly matches your rifle's length leaves no room for the end caps or padding to compress. Add the extra margin to your measurement, then find a bag whose internal length equals or exceeds that total. Checkpoint: if the bag's internal length is exactly your rifle length, it will be a very tight fit.
  3. Check internal height for scope clearance: Measure from the top of the scope's objective lens to the bottom of the rifle's stock. Compare that to the bag's internal height. If the bag height is less, the scope will press into the top padding, potentially causing damage. Common mistake: assuming all rifle bags have the same internal height. Always verify the spec.
  4. Test the fit with the bag zipped: Place the rifle inside the bag and zip it closed. The rifle should move minimally side-to-side and front-to-back. If it shifts more than an inch, the bag is too long. If the zipper strains, the bag is too short or too narrow. Checkpoint: a properly fitted bag protects the rifle during transport without forcing the zipper.
