If you need a tough, lightweight case that can handle real-world use while keeping your rifle and optics safe, the US PeaceKeeper P20040 MSR Case is built for exactly that.
Built for Modern Sporting Rifles – 40" Overall Length
This MSR case is sized specifically for AR-style and other MSR platforms:
That length gives you space for:
Rifles with standard collapsible stocks
Common configurations with mounted red dots, LPVOs, or scopes
Muzzle devices and rail accessories, without having to disassemble your setup
If you’ve ever tried to cram a properly configured AR into a too-short case, you’ll appreciate the room and fit of this 40" model.
600D Water-Resistant Polyester – Tough Exterior Shell
The exterior is made from 600 Denier water-resistant polyester, a proven fabric for hard-use gear: RK Guns+3BattleHawk Armory+3Impact Guns+3
600D poly resists tearing and abrasion from range benches, truck beds, and concrete
Water-resistant treatment helps repel light rain and splashes
Double-stitched seams increase strength at stress points and along the case body Firearms Depot+3Classic Firearms+3GrabAGun+3
This isn’t a flimsy promotional bag—it’s a dedicated rifle case designed to be used, not babied.
Brushed Tricot Liner – Soft, Moisture-Wicking Interior
Inside, the main rifle compartment is lined with brushed tricot, a soft, non-abrasive fabric: Firearms Depot+4GrabAGun+4BattleHawk Armory+4
Protects your rifle’s finish and optic from scratches
Helps wick moisture away from your gun after a damp day in the field or on the range
Makes sliding the rifle in and out smooth and snag-free
Whether your rifle is Cerakoted, anodized, or finely blued, that soft liner is a big step up from rough, unlined cases that can trap grit against your firearm.
2" Overall Padding – Real Protection for Rifle & Glass
US PeaceKeeper MSR cases are known for including two inches of total padding, not the thin foam you find in bargain cases. Firearms Depot+3GrabAGun+3BattleHawk Armory+3
What 2" padding gives you:
Better shock absorption against drops, knocks, and bumps
Extra protection for optics, lights, and other accessories
Structure that helps the case hold its shape instead of collapsing onto the rifle
For a soft case, this level of padding makes a real difference when you’re hauling gear to and from the range or stowing it in a vehicle.
External Zippered Pocket with Four Magazine Pouches
On the front of the case, you’ll find a large zippered accessory pocket that houses:
This external pocket lets you:
Carry up to four 30-round magazines (or similar)
Add tools, ear pro, gloves, or cleaning gear without needing a separate bag
Keep all your MSR essentials in one place for faster range trips
For most shooters, that’s everything you need for a typical session, packed into one compact setup.
Wraparound Handles & Sling Strap – Multiple Carry Options
The P20040 features wraparound carry handles that run completely around the case so they won’t tear free under load. Firearms Depot+3Classic Firearms+3GrabAGun+3
Carry options include:
Hauling a rifle, ammo, and gear can get heavy—having multiple comfortable carry methods is a big plus.
Lockable Double Zippers – Added Security & Compliance
The main compartment uses double zippers that can be brought together and secured with a small padlock (not included): RK Guns+4Classic Firearms+4Impact Guns+4
Lockable zippers help you:
Comply with transport rules that require a locked case in some jurisdictions
Add a level of security in shared spaces, vehicles, or club storage
Discourage casual access by unauthorized users
It’s a simple feature that’s increasingly important for responsible rifle owners.
Lightweight, Yet Built to Last – Lifetime Warranty
Despite its padding and rugged shell, the P20040 weighs only about 2.45 lbs, making it easy to carry alongside ammo cans and range bags. Classic Firearms+2DEGuns+2
Even better, US PeaceKeeper backs this case with a lifetime warranty, reflecting their confidence in the materials and construction. DEGuns
That combination of low weight, high durability, and lifetime support makes it an especially attractive choice for long-term use.
