MAGPUL PMAG® 20 LR/SR GEN M3™ Magazine Black

PMAG® 20 LR/SR GEN M3™

Carry full capability without unnecessary bulk. The PMAG® 20 LR/SR GEN M3™ combines a compact 20-round profile with proven feeding geometry to deliver the low profile precision shooters want and the reliability they demand. Designed for LR/SR pattern rifles, this magazine is ideal for prone shooting, bench work, and precision rifle setups where a shorter magazine makes a difference.

Built with an anti-tilt, self-lubricating follower and a long-life stainless steel spring, the PMAG 20 LR/SR provides smooth, consistent feeding across a wide range of conditions. Its next-generation polymer construction resists impacts and crushing forces, while remaining significantly lighter than comparable steel magazines. Easy serviceability and durable performance make this a trusted choice for serious shooters using .308 / 7.62 NATO platforms from Magpul.

Made in the USA.
