Magpul PMAG LR/SR Gen M3 Magazine - 20 Round

20-Round 7.62x51 PMAG

The Magpul PMAG 20 LR/SR Gen M3 is a 20-round polymer magazine for large-frame AR rifles chambered in 7.62x51mm. It is built for SR-25 pattern rifles, the AR-10 style platform whose magazine well and catch follow the SR-25 layout, which covers most modern .308 ARs. Twenty rounds keep the magazine short enough for prone shooting and bench work while still holding enough for a hunting day or a match stage.

Features

• 20-Round Capacity — Holds twenty cartridges in a body short enough to clear the ground when firing from prone or off a bipod.
• 7.62x51mm Chambering — The body is marked 7.62 x 51 with a cartridge outline on the upper spine, so you can tell it apart from a 5.56 magazine at a glance.
• SR-25 Pattern Fit — Designed for AR-10 style rifles that use the SR-25 magazine pattern, the most common layout among large-frame ARs.
• Gen M3 Design — The third generation of the PMAG, identified by the GEN M3 mark molded into the side of the body.
• Polymer Body — The molded polymer construction keeps weight down and will not dent the way a thin steel or aluminum magazine body can.
• Contrasting Follower — The follower, the spring-loaded platform that pushes rounds up, is a lighter color than the black body so an empty magazine is easy to spot.
• Textured Grip Panels — Raised ribs along the spine and a textured lower body give you a firm hold during reloads or with gloves on.
• Dot Matrix Marking Panel — A gridded area near the base gives you space to write a number or initials so you can track your own magazines.
• Flared Floorplate — The extended base gives your fingers something to pull on when stripping a magazine from a pouch or the rifle.
• Made In USA — Molded by Magpul Industries and marked Made in USA on the side of the body.

Fit and Construction

This magazine is made for SR-25 pattern large-frame AR rifles in 7.62x51mm. Check that your rifle takes SR-25 pattern magazines before ordering, because some older AR-10 designs use a different pattern. The black polymer body carries the Magpul markings and PMAG 20 LR/SR designation on its side, and the floorplate sits flush at the base with a small flare for grip.
