Magpul PMAG 10/30 AR/M4 GEN M3 Rifle Magazine 5.56mm 30/rd

The Magpul Industries PMAG 10/30 AR/M4 GEN M3 gives shooters in capacity-restricted states the full-size feel of a 30-round magazine while holding only 10 rounds. It carries the same external footprint as a standard GEN M3 body, so it indexes, seats, and handles like the magazines most AR-15 shooters already run, but a permanent internal limiter keeps the load to 10. That makes it a straightforward choice for range use, training, and hunting where the law caps you at ten. Anyone building or feeding a 5.56mm AR-15 in a restricted jurisdiction will find this magazine slots into the same workflow as the rest of the GEN M3 line. Browse the full range of rifle magazines to round out a build.

This is a polymer 5.56x45mm NATO magazine built on the GEN M3 platform, chambered to feed AR-15 and M4 pattern rifles. The 30-round-size body is internally restricted to a 10-round capacity, so it grips and inserts identically to a full-capacity magazine while staying within state limits. Magpul Industries carries the SKU MAG1183 / MPN MAG556-MCT for this configuration. The GEN M3 design uses a four-way anti-tilt follower and a stainless steel spring to keep feeding consistent, along with a paint-pen dot matrix on the body for marking and a flared floorplate that helps with positive extraction during reloads. For shooters who want extra length on a five-round-class magazine, the Warne PMAG extension is also worth a look.

Reach for this magazine when you live or hunt in a state that caps rifle magazines at 10 rounds but you still want the handling of a full-size unit. The reduced capacity keeps you compliant on the range, in the field, and at matches where the rules require it, without forcing you to retrain on a shorter magazine. It feeds 5.56mm NATO and .223 Remington from any standard AR-15 or M4 lower. Pair it with other 5.56mm options like the DuraMag 30-round magazine, or compare it against the rest of our AR-pattern stock when planning a loadout.
