Aim Sports MT45FS AR Low Profile 45 Degree Flip-Up Sight Set Black Anodized 45 Degree Low Profile for AR-15

AR platforms need sighting solutions that mount cleanly without interference from optics or rail systems. The MT45FS delivers angled acquisition at 45 degrees, letting shooters transition between primary optics and backup irons. Whether you're building in Sunnyvale, Oakland, or anywhere in California, understanding local regulations matters—review California firearm laws before finalizing your setup.

Angle-Mount Design and Elevation Range

The 45-degree flip-up configuration positions these sights off the primary sight line, ideal for shooters running red dots or magnified optics on the flat-top rail. With 49 MOA of elevation adjustment built in, you can dial zero at multiple distances without secondary tools. Installation follows standard AR rail practices. Questions about transfers or ownership?

Frequently asked questions

Do these flip-up sights work with all AR-15 platforms?

Yes. The MT45FS mounts to any Picatinny rail, including flat-top uppers on direct impingement and piston systems. Verify your rail height matches your optic setup to avoid interference.

What does 49 MOA elevation adjustment actually give me?

49 MOA covers most practical zero distances from 25 to 100+ yards depending on your ammunition and barrel length. Dial fine adjustments to match your optic's point of aim.
