Built for AR-10 / LR-308 / SR-25 Pattern Rifles
This HEXMAG 20-round magazine is engineered specifically for SR-25/DPMS pattern .308 rifles (often generically called AR-10 style rifles):
Compatible with DPMS LR-308, Knight’s SR-25, and many other 7.62 AR platforms using the SR-25 magazine pattern.
Chambers .308 Winchester and 7.62x51 NATO, making it ideal for hunting, precision shooting, and tactical use.
Not for use in M1A, FN FAL, or other non-SR-25 pattern rifles.
If your .308 AR takes SR-25/LR-308 style mags, this HEXMAG is designed to fit right in.
20-Round Capacity – Perfect Balance of Size & Firepower
With a 20-round capacity, the HX20-SR25-BLK strikes a great balance between ammunition load and handling:
Ideal for bench shooting, prone work, and precision shooting, where 20-rounders are easier to manage than long 25+ mags.
Great for battle rifles and duty setups, providing ample firepower without excessive weight or length.
More capacity than 10-round mags, but still compact enough for practical field use and easier carry in pouches.
Whether you’re running drills, shooting long-range steel, or setting up a defensive rifle, 20 rounds is a versatile sweet spot.
Impact-Resistant Black Polymer Construction
HEXMAG magazines are known for their tough, lightweight polymer bodies, and this .308 version is no exception:
Constructed from a reinforced, impact-resistant polymer that stands up to drops, impacts, and rough field use.
The black finish gives a classic, low-profile tactical look that pairs well with almost any rifle color scheme.
Resists corrosion, dents, and deformation better than metal mags in many hard-use environments.
You get a magazine that’s built to handle training, competition, and real-world conditions without weighing down your rifle.
HEXTURE™ Grip Pattern – Secure Handling in Any Conditions
HEXMAG’s signature HEXTURE™ hexagonal surface pattern isn’t just cosmetic—it’s functional:
Provides a non-slip gripping surface for fast mag changes, even with wet or gloved hands.
Improves control when pulling mags from pouches, chest rigs, or belt carriers.
Adds a distinctive HEXMAG look that stands out from generic smooth-sided magazines.
In high-stress or adverse conditions, better grip equals more consistent reloads.
Tool-Free Floor Plate – Easy Disassembly & Cleaning
The HX20-SR25-BLK is designed for simple maintenance:
Tool-free floorplate design allows you to disassemble the magazine quickly for cleaning and inspection.
Makes it easy to clear debris, sand, and carbon buildup after hard use or dirt-prone environments.
Reassemble in seconds, keeping your mags in top shape with minimal hassle.
A clean magazine is a reliable magazine, and HEXMAG makes that upkeep easy.
Reliable Feeding for .308 / 7.62 NATO
A magazine is only as good as its feeding performance. This HEXMAG is built to run:
Optimized follower geometry and internal design for smooth, consistent feeding with .308 Win and 7.62 NATO.
Robust spring tension designed to maintain reliability over many loading cycles.
Anti-tilt follower and well-designed feed lips help minimize the risk of misfeeds, nose dives, or double feeds.
From slow-fire groups to rapid strings, this mag is engineered to keep your .308 AR cycling smoothly.
Lightweight Yet Durable – Ideal for Loadouts & Classes
Because it’s polymer, this HEXMAG 20-rounder is lighter than many steel mags, making it a smart choice for:
Training classes and carbine courses, where multiple magazines are carried and cycled all day.
Competition and 3-Gun (where allowed), helping reduce total loadout weight.
Hunting setups, where every ounce counts and you still want plentiful capacity.
Carry more mags with less fatigue, and enjoy the weight savings without sacrificing strength.
Perfect for Tactical, Hunting & Precision Roles
The versatility of a 20-round .308 mag makes this HEXMAG useful in a wide range of roles:
Tactical & defensive rifles – ample capacity while still managing overall rifle length and balance.
Hunting rigs – especially when you want more than a low-capacity hunting mag but still favor a compact profile.
Precision semi-auto builds – where 20-round mags are commonly preferred for bench and prone shooting.
No matter how you run your SR-25/DPMS pattern rifle, this magazine is ready to support it.
