Whether you’re hauling a scoped AR to a carbine class, transporting a modern sporting rifle to the range, or storing your rifle safely at home, the US PeaceKeeper P20045 MSR Case is built to keep your investment safe, organized, and ready to go.
Built for Modern Sporting Rifles – 45" Exterior Length
The P20045 is sized specifically for AR-style and other modern sporting rifles:
Exterior dimensions: approx. 45" L x 12.5" H (variously listed around 45" x 11"–12.5" x 2.75") shop.xcal.com+3DEGuns+3Impact Guns+3
Ideal for 16"–18" AR-15 carbines with collapsible stocks and mounted optics
Also fits many tactical and hunting rifles that fall within the 45" envelope
That length gives you enough room for:
Rifles with LPVOs, red dots, or traditional scopes
Common muzzle devices, low-profile bipods, and accessories
A standard MSR setup without needing to break the rifle down
If you’ve ever tried to stuff a real AR build into a too-small case, you’ll appreciate the extra room and smart proportions of this 45" MSR case. Palmetto State Armory+1
600D Water-Resistant Polyester – Tough Exterior Shell
The outer shell of the P20045 is made from 600 Denier water-resistant polyester, giving you a rugged, field-ready rifle case that shrugs off daily abuse: Starlight Tactical+4GrabAGun+4DEGuns+4
600D fabric resists tearing, fraying, and abrasion from benches, truck beds, and range surfaces
Water-resistant treatment helps repel light rain and splashes, protecting your rifle from moisture
Double-stitched seams throughout add durability at stress points, so the case holds up under real use
This isn’t a flimsy sleeve—it’s a purpose-built soft case designed for hard-running ARs and regular range trips.
Brushed Tricot Liner – Soft, Moisture-Wicking Interior
Inside, the MSR Case uses a brushed tricot liner, a soft, fabric-style interior that:
Helps wick moisture away from your rifle, reducing the chances of condensation sitting on metal surfaces
Protects delicate finishes, Cerakote, and optics from scuffs and scratches
Lets the rifle slide in and out smoothly without snagging on sharp or rough surfaces Starlight Tactical+3DEGuns+3Palmetto State Armory+3
For rifles with quality finishes or glass, this interior is a big upgrade over bare or rough-lined cases.
2" Overall Padding – Real Impact Protection
Each US PeaceKeeper MSR case, including the P20045, is built with two inches of overall padding, not the thin foam you see in bargain bags. TheGunZone+4DEGuns+4Palmetto State Armory+4
Benefits of the thicker padding:
Cushions your rifle and optic against bumps, drops, and rough handling
Adds structure so the case holds its shape even when empty
Protects everything from muzzle devices and stocks to scopes and rail accessories
If you transport your rifle frequently—or share range time with friends and students—this level of padding offers peace of mind every time you zip the case shut.
External Zippered Pocket with Four Magazine Pouches
On the outside of the case, you get a large zippered accessory pocket housing four individual magazine pouches: RifleGear+4GrabAGun+4Palmetto State Armory+4
Each pouch is sized for AR-style magazines, giving room for up to four 20- or 30-round mags
Pouches use hook-and-loop (Velcro) flaps for secure retention during movement
The main pocket space can also hold tools, small cleaning kits, ear/eye pro, gloves, or targets
This keeps your rifle and core ammo load together in one organized, grab-and-go package.
Lockable Double Zippers – Security & Transport Compliance
The main rifle compartment features double zippers with robust pulls, designed to be lockable: RK Guns+4GrabAGun+4DEGuns+4
Bring both zipper heads together and add a small padlock (not included)
Helps you comply with locked-case transport requirements in many jurisdictions
Adds a layer of security when storing the rifle in a vehicle, shared living space, or club locker
For responsible gun owners, lockable zippers are now a must-have feature—and the P20045 delivers.
Wraparound Handles & Sling Strap – Multiple Carry Options
Carrying a fully loaded rifle case should feel secure and controlled. US PeaceKeeper uses full wraparound handles and a removable sling strap to make that happen: Starlight Tactical+4Palmetto State Armory+4Impact Guns+4
Handles wrap completely around the case, distributing weight and preventing pull-outs at a single stitched point
A removable padded shoulder strap lets you carry the case hands-free from the car to the bench or across the range
At roughly 2.8 lbs empty, the case is light enough to manage easily while still feeling substantial and protective DEGuns+2US PeaceKeeper+2
Whether you prefer briefcase-style carry or shoulder carry, you’ve got options.
Thoughtful, Range-Ready Design Details
Beyond the big features, the P20045 includes a number of thoughtful details that make it a true range companion:
Double-stitched construction for long-term durability Palmetto State Armory+2Impact Guns+2
Slim, low-profile shape that doesn’t scream “tactical” from across the parking lot
Simple, professional black finish that looks at home in the truck, safe, or club
It’s the kind of case you can use for training classes, competition days, hunting trips, and everyday transport without feeling like you’re over- or under-geared.
