A good gun case protects your firearm and keeps you within the law during transport. You'll want one that fits your gun and accessories properly while staying secure and legal to transport. When you're going to the range, on a hunting trip, or storing your firearm at home, the right case size keeps your equipment safe and gives you room for important items like scopes, ammo, and cleaning tools. This guide covers what you need to know about picking a case - from basic measurements to safety features - so you can choose one that works well for your needs.
Firearm Dimensions and Measurement Guide
The right gun case starts with accurate measurements of your firearm. Having precise dimensions helps you find a case that fits perfectly and protects your equipment properly.
Standard Firearm Dimensions
| Firearm Type | Typical Length Range | Common Width Range | Height Range | Notes |
| Hunting Rifles | 38-46 inches | 2.5-4 inches | 7-9 inches | Length varies with barrel size |
| Tactical Rifles | 30-36 inches | 2.5-4 inches | 7-10 inches | Often shorter for maneuverability |
| Shotguns | 26-48 inches | 2.5-3.5 inches | 6-8 inches | Break-action types can be shorter |
| Full-Size Handguns | 7-10 inches | 1-1.5 inches | 5-6 inches | Includes most service pistols |
| Compact Handguns | 6-7 inches | 1-1.25 inches | 4-5 inches | Popular for concealed carry |
| Competition Rifles | 40-50 inches | 3-5 inches | 8-12 inches | Often have larger scopes |
How to Measure Your Firearm Correctly
- Start with these basic tools:
- A tape measure or yardstick
- Paper and pencil to note measurements
- Your firearm in its most extended configuration
Take these measurements:
- Overall length: Measure from the very tip of the barrel to the end of the stock or grip
- Height: Measure from the bottom of the magazine or grip to the highest point
- Width: Include the widest point, usually at the scope or action
Including Attachments in Your Measurements
Your case needs to fit more than just the basic firearm. Remember to account for:
- Scopes and optics (usually adds 3-6 inches in height)
- Extended magazines
- Bipods or stabilizers
- Tactical lights or lasers
- Suppressors if you use them
Special Considerations
Folding or collapsible stocks affect your case needs. Measure both the collapsed and extended positions. Some firearms, like break-action shotguns, can be partially disassembled for transport - this might let you use a shorter case.
A proper fit means your firearm won't slide around inside the case. The interior padding should touch the gun at multiple points without pressing too tightly against scopes or other sensitive parts.
How to Determine the Right Gun Case Length
After measuring your firearm, adding 2-4 inches to the total length gives you the minimum case size needed. These extra inches make the difference between a tight squeeze and a proper fit that protects your equipment.
Extra Space Requirements
The right case length accounts for:
- 1-2 inches of padding at the muzzle end
- 1-2 inches of padding at the stock end
- Space for recoil during transport
- Room for retention straps or securing mechanisms
Recommended Length Guidelines
| Firearm Type | Add to Total Length | Reason |
| Standard Rifles | 2-3 inches | Basic protection needs |
| Scoped Rifles | 3-4 inches | Extra padding for optics |
| Tactical Rifles | 3-4 inches | Room for attachments |
| Shotguns | 2-3 inches | Standard protection |
| Competition Guns | 4-5 inches | Space for specialized gear |
Planning for Modifications
If you expect to add or change equipment, consider:
- Scope additions: Add 1-2 inches
- Extended barrels: Add 2-3 inches
- Suppressors: Add 6-8 inches
- Muzzle devices: Add 1-2 inches
These measurements ensure your case remains useful even as your firearm setup changes. A case that's slightly too long works better than one that's too short - but avoid going more than 6 inches beyond your current needs, as excessive space can allow harmful movement during transport.
Gun Case Length Examples and Recommendations
The exact length you need depends on how and where you'll use your firearm. Each type of shooting activity has its own specific requirements for protection and convenience.
Case Lengths by Activity
| Activity | Recommended Length | Key Considerations |
| Home Storage | Exact gun length + 2" | Minimal padding needed |
| Local Range Trips | Gun length + 3-4" | Room for basic cleaning kit |
| Competition Travel | Gun length + 4-6" | Space for spare parts, tools |
| Hunting Trips | Gun length + 3-5" | Weather protection gear |
| Air Travel | Gun length + 4-6" | Extra padding for rough handling |
Case Length Adjustments for Transport Methods
Vehicle Transport
- Trunk storage: Standard length works fine
- Back seat: Consider shorter case with breakdown firearms
- Truck rack: Add 2" for extra weather protection
Public Transport
- Bus/Train: Compact cases preferred - consider takedown models
- Airlines: Must meet TSA requirements - check carrier guidelines
- Multiple transfers: Extra padding needed - add 1-2"
Real-World Length Examples
Hunting Setups
- Remington 700 (44" total) → 48" case
- Mossberg 500 (48" total) → 52" case
- AR-15 with scope (36" total) → 40" case
Competition Setups
- Precision rifle with bipod (46" total) → 52" case
- 3-Gun rifle setup (40" total) → 46" case
The ideal case length should match your most frequent use case. This approach helps maintain proper protection while avoiding the need for multiple cases.
Gun Case Laws and Security Standards
Gun case requirements vary by location and situation. A thorough review of current regulations before transport is essential, as laws can change frequently.
Federal Transportation Rules
The Transportation Security Administration maintains strict guidelines for flying with firearms. All guns must travel in hard-sided, locked containers as checked baggage only. At the check-in counter, passengers must declare their firearms. The TSA specifically requires all firearms to be completely unloaded before transport, with no exceptions to this policy.
State Transport Requirements
State laws governing gun transport show significant variation across regions. The most reliable sources for accurate information include state attorney general offices and local law enforcement agencies. Transportation rules may differ between states, making it crucial to research requirements before crossing state lines. Gun owners should pay particular attention to any recent changes in local regulations.
Lock Types and Security Features
Common security features in modern gun cases include:
- Key locks
- Combination locks
- Multiple locking points
- Steel reinforced edges
- Padlock attachment points
The best approach is to check current local and state regulations before transport and verify requirements with relevant authorities. This ensures compliance with the most up-to-date rules in your area.
Choose Your Perfect Gun Case Length!
Your gun case protects your valuable firearm and helps you follow the law. A properly sized case needs exact measurements of your gun plus room for accessories and padding.
