The Griffin Armament M2 flip-up rear sight is a modular backup iron sight engineered for shooters who demand versatility without sacrificing durability. Built from QPQ-treated 17-4 stainless steel and ordnance-grade steel, this rear sight mounts to standard Picatinny rails and pairs with Griffin's M2 front sight to create a complete low-profile backup system. The real innovation here is the patent-pending modular base plate design: the rear sight ships with a vertical 12 o'clock mounting plate and accepts optional angled base plates separately, so you can reconfigure the sight to ambidextrous 45-degree positions as your rifle setup changes. No more relegated to a forgotten box when your optic mounts shift.
Weighing just 2.5 ounces, the M2 rear sight keeps your rifle lean while delivering genuine aiming capability when glass fails or conditions demand iron-only performance. The flip-up tower features robust spring tension that ensures consistent repeatability shot after shot, while a low-profile, snag-resistant slotted windage screw allows smooth yet secure adjustment without unnecessary complexity. This is a backup sight built to actually get used—whether you're running a precision rifle, a duty carbine, or an intermediate setup where redundancy matters.
Griffin designed the M2 to stay out of the way: it's among the smallest backup sights available and designed to coexist with optics mounted on-axis or offset. The system works in rain, snow, and fog without batteries or electronics, and it's compatible with standard A2-pattern sight posts if you want to upgrade with aftermarket tritium, fiber optic, or match-grade inserts down the road.
| Material | 17-4 stainless steel (QPQ Melonite treated), ordnance-grade steel |
| Mount Type | Picatinny rail |
| Included Bases | 12 o'clock vertical mounting plate |
| Weight | 2.5 ounces |
| Sight Post Compatibility | A2-pattern posts (tritium, fiber optic, match-grade compatible) |
| Configuration Options | Modular—alternate 45-degree angled plates available separately |
The rear sight is available separately, so you can purchase it on its own. However, Griffin designed the M2 as a complete system—front and rear sights work together to form your backup iron system. You're not locked into buying the full kit if your current setup only needs a rear sight replacement.
The M2 rear sight ships with a 12 o'clock mounting plate, which positions the sight directly on top of your Picatinny rail for co-witnessing or offset optics. Angled base plates (sold separately) allow you to reconfigure the sight to ambidextrous 45-degree mounting, giving you flexibility to adapt the sight to different rifle configurations without buying a new sight.
Yes, the M2 rear sight mounts to any standard Picatinny rail. The modular design works with typical AR-15 top rails, free-float setups, and other platforms using Picatinny mounting. Confirm your rifle has a Picatinny rail slot before ordering.
The M2 rear sight is compatible with A2-pattern sight posts, so you can upgrade to aftermarket tritium, fiber optic, or match-grade inserts if you choose. These upgrades are available separately and allow you to customize the sight's visibility to your preference.
