MAGPUL · PMAG · GEN M3
AR/M4 magazine with clear variant choice instead of caliber guessing
The PMAG AR/M4 GEN M3 is designed for compatible AR-15/M4 systems in the 5.56-/ .223 context. The Shopify variants differ in capacity and color – not in the basic platform logic.
10 or 20 rounds · 5.56/.223



Black-Raptor classification
A sensible purchase if your system uses the AR-15/M4 magazine standard and you have clarified capacity and legal framework beforehand. Not to be read as a universal magazine for other platforms or calibers.


Fits your setup?


Fits well For compatible AR-15/M4 systems in 5.56 NATO or .223 Remington, if you consciously choose between the 10- and 20-round variant.

Fits rather not For AR-10/SR-25, AK, AICS or other magazine standards – visually similar magazines are technically not interchangeable.



Features that matter in everyday use


GEN-M3-PMAG line Proven Magpul magazine logic for the matching AR/M4 magazine well.

Polymer construction Corrosion-resistant and lightweight; the actual fit depends on the specific system.

10- or 20-round variants Capacity affects handling, height, and legal usability.

Black or O.D. Green Color choice without changing the intended platform.



Limits and miska
Misuse prevention
AR-15/M4-compatible does not automatically mean suitable for every semi-automatic rifle in caliber .223/5.56. The decisive factor is the actually used magazine well. Also check the currently applicable legal regulations on magazine capacity and usage.


Technical data with practical consequences


Platform AR-15/M4 context Practical consequence: Magazine well must correspond to the respective standard.

Caliber context 5.56 NATO / .223 Remington Practical consequence: do not transfer to other PMAG families.

Capacities 10 or 20 rounds Practical consequence: affects overall height and legal usability.

Material Polymer Practical consequence: lightweight magazine; check fit and function on your own system.



Scope of delivery
1 × Magpul PMAG AR/M4 GEN M3 in the chosen capacity and color variant


Application and safety
Check magazine fit and locking only in an unloaded, safe system. Before first use, check feeding, locking, and free fall or removal. Observe legal regulations on capacity and use.


Frequently asked questions
Does it fit in AR-10 or SR-25? No, a different PMAG family is intended for that. This page refers to the AR-15/M4 context. What distinguishes the variants? Capacity and color: 10 or 20 rounds as well as Black or O.D. Green. Is 5.56 NATO synonymous with universal compatibility? No. Both caliber designation and magazine well must fit. What is the most common wrong purchase? Ordering only by caliber and not checking the actual magazine standard of the firearm.


Clear purchase decision: Right for compatible AR-15/M4 setups in 5.56/.223; wrong if platform standard or desired capacity do not clearly fit.
