The PolyTac seems like a great light so far and the Magpul mount is pretty versatile. Used a right side mount on the top rail to position the light at 11 o'clock. With the AFG2 this puts my thumb right in position to activate the light...

PolyTac®
The all-purpose PolyTac is designed for the broadest range of lighting applications at the best value. It features a superior grip texture for a comfortable but slip-resistant feel, as well as TEN-TAP® Programming that gives users the choice of three operating modes.
- C4® LED technology within a parabolic reflector produces a concentrated beam with optimum peripheral illumination
- TEN-TAP® Programming: Choice of three operating modes:
1.) high/strobe/low (factory default); 2.) high only; 3.) low/high:
- High for bright light: 275 lumens; 9,500 candela; 195m beam distance; runs 3 hours
- Low for when less light is needed and for longer run times: 14 lumens; 500 candela; runs 65 hours
- Strobe for disorienting or signaling: runs 5.5 hours
- Solid State power regulation provides maximum light output throughout battery life
- Reflector produces a concentrated beam with optimum peripheral illumination — ideal for law enforcement backup light; day-to-day industrial use; maintaining vehicles; general contracting work
- High-impact, super-tough nylon polymer for exceptional durability and a superior grip texture to provide a comfortable but slip-resistant feel
- IPX7 rated design; waterproof to 1 meter for 30 minutes
- Powered by two 3V CR123A lithium batteries (included)
- 5.34 in. (13.56 cm); 4.2 oz (121 grams) with batteries

The Rail Light Mount fits on any standard 1913 Picatinny Rail, is available in right or left side models, and integrates with the Magpul XTM panels. It positions the weapon light high and cantilevered forward, at the 11 o'clock or 1 o'clock position, to allow a more forward support hand position, keep the light tucked in close to the bore, and to minimize barrel shadow. A textured thumb ramp is integrated to provide the user an index point, aiding consistent hand placement and light activation.
Constructed of reinforced polymer, the Rail Light Mount nearly eliminates light compatibility concerns by conveniently including everything you need to mount Surefire 300 and 600 series Scout Lights, 1913 Picatinny attachment pistol lights, and all light bodies from 0.75" to 1.03" in diameter via the included set of anodized aluminum mounting rings.
Models are available to position the light high at 11 o'clock (LT, Left side model) or one o'clock (RT, Right side model).
Made in U.S.A.
