The Magpul PMAG LR/SR Gen M3 magazine for .308 Winchester is a lightweight, reliable polymer magazine purpose-built for AR-10 pattern rifles, SR-25 pattern rifles, and precision platforms like the Ruger Precision Rifle. If you're running an LR-308 or modern SR-25 clone and want a magazine that feeds consistently and handles like it's meant to, this is a solid choice for match shooting, long-range work, or tactical drills.
Magpul engineered this Gen M3 version with a constant-curve body that feeds rounds smoothly, paired with a stainless steel spring and anti-tilt follower that self-lubricates for reliable operation across extended use. The 10-round capacity fits the LR/SR platform in a compact, lightweight footprint. The flared floorplate isn't just for looks—it makes magazine handling more positive, aids field disassembly, and improves drop protection. Aggressive front and rear texture grips your fingers well, even gloved, and the ribbed sides give you something to hold onto when loading or dropping the mag fast.
Field-stripping the mag takes no tools. Unload, flip the floorplate, and the internals come apart for cleaning. The polymer construction is Magpul's impact and crush-resistant formula, proven in countless professional and civilian arsenals. Made in the USA. Note that this magazine is optimized for .308 Winchester match ammunition with a maximum OAL of 2.830", and while it works with many modern AR-10 variants, it's not compatible with M14-pattern, FAL-pattern, or HK 91/G3-pattern guns, nor with some older DPMS GII designs. Check your rifle's pattern before ordering.
