The Magpul PMAG 30 round window GEN2 MOE in OD green—proven polymer magazine for AR-15 rifles in 5.56 NATO with a side viewing window for quick round counts.
The Magpul PMAG 30 Round AR/M4 Window GEN2 MOE is a polymer magazine designed for AR-15 and M4 pattern rifles chambered in 5.56 NATO. This OD green version holds 30 rounds and features a side viewing window that lets you check remaining ammunition at a glance. The GEN2 MOE series is widely used across sport shooting, home defense, and training applications.
The side window provides round-count visibility without removing the magazine. The window is positioned to show when rounds drop below ten, giving you an early heads-up for reloads during extended range sessions.
The OD green finish sets this magazine apart visually and makes it easy to distinguish from black or flat dark earth gear on a crowded bench or in a range bag.

What the Window Does for You
A windowed PMAG lets you confirm loaded status without press-checking the feed lips or pulling the magazine for a visual. That matters in classes where you need to stage loaded mags before a drill, or during a multi-gun match where you want a fast decision on whether to reload.
The GEN2 MOE series is compatible with the MAGPUL range of magazine accessories, including dust covers and base plates. Polymer magazines like the PMAG have become the standard for training and recreational shooting because they balance durability with a lower cost than steel or aluminum alternatives.
OD Green vs Black or FDE Mags
Most shooters run black magazines because that is what ships with most rifles. OD green pmags let you color-code your gear—load them with a specific load, mark them for a particular rifle, or simply keep range mags separate from duty mags by color alone.
Green also stands out if you drop a mag during a class or match. A black mag on dark gravel disappears; OD green does not. If you are building an OD green AR-15 or matching a specific color scheme, these mags complete the look.
PMAG Compatibility with AR-15 Rifles
The GEN2 MOE works in STANAG-pattern magazine wells on AR-15 and M4 rifles chambered for 5.56 NATO or .223 Remington. Most modern mil-spec and commercial ARs accept these magazines without modification. Billet lowers and some older surplus receivers may require fitting.
If you have an AR with a non-standard mag well or an aftermarket lower, call 817-393-4000 to confirm fit before ordering. Our gunsmith can also advise on compatibility with specific builds or conversions.

Frequently Asked Questions
Q: Does the Magpul PMAG 30 round window GEN2 in OD green work in any AR-15?
A: This magazine fits most mil-spec and commercial AR-15 and M4 rifles with STANAG-pattern magazine wells chambered in 5.56 NATO or .223 Remington. Some billet lowers and older surplus receivers may require fitting. Call 817-393-4000 to confirm compatibility with your specific rifle.
Q: What is the difference between a windowed PMAG and a standard PMAG?
A: The windowed version has a polymer viewing window on the side that allows you to see remaining ammunition without removing the magazine from the rifle. The standard PMAG lacks this window. Both versions are otherwise identical in capacity and function.
Q: Can I use 5.56 NATO magazines for .223 Remington?
A: Yes. A magazine marked for 5.56 NATO will feed .223 Remington ammunition without issue. The cartridge dimensions are nearly identical, and the magazine does not determine pressure—only the chamber does. This PMAG works for both calibers.
Q: Why choose OD green pmags over black magazines?
A: OD green magazines let you color-code your gear for quick identification—separate different loads, mark mags for a specific rifle, or distinguish range mags from duty mags by color. Green is also easier to spot if you drop a magazine on dark surfaces during training or competition.
Q: How do I order magazines from Western Sport if I live outside Roanoke?
A: Magazines ship to most states without an FFL transfer, though a few states restrict magazine capacity or require special handling. Call 817-393-4000 to verify ship-to eligibility for your address and place an order over the phone, or order online through our shop page.
Q: Who makes the best polymer AR magazines?
A: Magpul PMAGs are the most widely tested polymer magazines in service and sport shooting. The GEN2 MOE series has been in production for over a decade and is used across law enforcement, military trials, competition, and recreational shooting. Other polymer options exist, but Magpul remains the benchmark.
