The Low Power Scope is a bit of a cross between a sniper scope and a regular optical attachment. The player retains HUD elements when aiming down the sight, but the user's peripheral vision is blacked out. It has a zoom level equivalent to the low zoom setting on the Variable Zoom Scope. The Low Power Scope uses a red Lambda reticle.
The G11 receives significant idle sway with the Low Power Scope that cannot be steadied. The sway speed is also 33% faster than normal. The G11's aim down sight time is also slowed down to 300 milliseconds versus the traditional 250 milliseconds. These disadvantages, in tandem with the blotting out of peripheral vision, make the Low-Power Scope a traditionally unpopular attachment in Multiplayer. Apart from the enhanced zoom level, the Low Power Scope is a direct downgrade from the stock G11 that compromises the G11's greatest strength as a weapon: its accuracy.
In Zombies, the Low Power Scope is used on the G11. It can be found in the Mystery Box. When Pack-A-Punched, the Low Power Scope's sway is removed. Also, a G11 with a Low Power Scope can be found in one of the later weapons caches in "Numbers", without any sway.
- While using the Classic Controller on the Wii, it has no sway at all.
- The inside of the Low Power Scope turns gold when the G11 is fitted with Gold Camouflage. The exterior, however, remains black.
- In Call of Duty: Modern Warfare 3, the reticle for the Low Power Scope returns as a usable reticle called "Lambda" for the ACOG Scope, the Red Dot Sight, and the Holographic Sight.
