This Sightmark battery pack will power your optics – giving you more time at the range, or in the bush, and less time sitting next to a wall outlet. This battery pack will fit any device with a Universal USB Type A, including the Wraith HD series. This weighs a mere 9 ounces, to avoid overloading your firearm. Featuring a “battery-charging” indicator, and made of durable, flame-retardant ABS, this battery pack is an excellent addition to any shooting system.
