The Lancer Systems L7AWM magazine is a 10-round, 7.62x51mm/.308 Winchester polymer magazine engineered for AR-10 platform rifles. Built on lessons learned from proven military designs, this magazine combines lightweight polymer construction with hardened steel feed lips that encircle the entire perimeter—a design choice that boosts rigidity, prevents feed failures, and eliminates the dimpling that can plague front-loading scenarios. If you run an AR-10, this is the kind of reliable, durable magazine that lets you focus on accuracy and shot placement rather than worrying about your ammunition.
The opaque design keeps things straightforward: no translucent walls to check round count at a glance, just solid construction that's made in the USA. A standout feature is the switchable drain lock built into the floor plate. Flip it on in wet, muddy, or salt-spray conditions to seal out the elements; flip it off in normal use or dusty terrain where you want any water or debris to drain freely. This adaptability means one magazine can handle backcountry hunts, coastal trips, or desert ranges without compromise.
If you're building or upgrading an AR-10 for long-range hunting, precision rifle matches, or tactical drills, having a magazine you can trust is non-negotiable. Lancer's reputation for polymer reliability is well-earned, and this 10-rounder delivers the capacity and durability that serious shooters expect.
| Caliber | 7.62x51mm / .308 Winchester |

| Material | Polymer with hardened steel feed lips |

| Country of Origin | USA |
Yes—the Lancer L7AWM is designed specifically for AR-10 platform rifles in 7.62x51mm/.308 Winchester.
The drain lock in the floor plate can be toggled between sealed and open modes. Lock it for wet or salty conditions to keep moisture and debris out; leave it open for normal use so any water or dust drains freely.
Hardened steel feed lips encircle the entire magazine perimeter, which stiffens the structure, prevents front dimpling, and ensures consistent, reliable feeding—especially important under rapid fire or in harsh conditions.
No—the Lancer L7AWM is opaque polymer, so you won't be able to see your round count at a glance. If round-count visibility is important to you, you'll need to check capacity manually or choose a translucent model.
