Description
The PMAG 10 LR/SR Gen M3 is engineered for shooters who want every advantage when precision matters most. Whether you're running a precision rifle from the bench, hunting with a bipod, or working with platforms that benefit from a lower-profile magazine, this 10-rounder delivers the same Gen M3 technology Magpul's known for in a compact package. Built for SR25 and M110 pattern rifles, it works across a wide range of AR-10 platforms and clocks in at roughly half the weight of traditional steel magazines.
Feeding and Reliability You Can Count On
This magazine features a stainless steel spring, anti-tilt self-lubricating follower, and constant-curve internal geometry that work together to guarantee smooth feeding through all conditions. The design handles both standard SAAMI-spec rounds and longer match ammunition up to 2.830 inches overall length, so whether you're running M118LR or other precision loads, the mag adapts to what you throw at it. The follower moves freely and predictably every single time.
Built to Last, Easy to Maintain
The crush-resistant polymer body takes hits that would dent steel, and the construction exceeds most military performance standards. A flared floorplate makes disassembly tool-free, so cleaning takes just a couple minutes. That same floorplate is slimmed down to fit tight in multiple magazine pouches without snagging. A paint pen dot matrix on the bottom lets you mark your loads for quick identification at the range or in the field.
Compact Size, Full PMAG Strength
At 10 rounds, this mag stays low-profile in the magazine well while keeping all the strength and reliability of larger capacity models. Perfect for use with bipods or when shooting off a pack, and compact enough to work in situations where lower capacity is preferred.

Frequently Asked Questions
What rifles will the PMAG 10 LR/SR Gen M3 work with?
This magazine is optimized for DPMS LR/SR-25 pattern AR-10s and fits a wide range of commercial rifles including the KAC SR25, Colt LE901-16S, LaRue OBR, JP Enterprises LRP-07, Bushmaster .308 ORC, S&W M&P10, SIG716, and many others. It's NOT compatible with Armalite AR-10B or M1A-style platforms. Always verify your specific rifle's compatibility before ordering.
Is this magazine suitable for hunting?
Absolutely. The 10-round capacity makes it ideal for hunting where you want a lower-profile magazine on your rifle or in certain hunting applications. You can also pair it with Magpul's optional Minus Five Round Limiter if you need even lower capacity for specific hunting regulations.
How does the PMAG 10 compare to steel magazines?
The PMAG 10 weighs less than half what a steel .308 magazine weighs while delivering the same reliability. It's built with impact and crush-resistant polymer, a quality stainless steel spring, and an anti-tilt follower. The lighter weight matters when you're carrying gear all day, and the durability matches or exceeds that of steel mags over a rifle's service life.
Will this magazine work with longer match ammunition?
Yes. The magazine is optimized for ammunition up to 2.830 inches overall length, including M118LR and other precision match rounds. The constant-curve internal geometry accommodates both standard SAAMI-spec rounds and longer loads without binding or feed issues.
