Perforator

The  is a unique version of the Infiltrator, available in the Fallout 3 add-on The Pitt. It can be obtained from Everett during the quest Unsafe Working Conditions after handing in 90 Steel Ingots.

This version is much more powerful than the Infiltrator, and has a smaller spread than it as well.

Characteristics
Characters with a high luck will benefit more from this rifle, as it has the highest critical rate of any assault rifle. This weapon fires slower than the Infiltrator, about 1 time for every 1.5 times the Infiltrator does. It only fires two shots per V.A.T.S. hit as opposed to most other assault rifles, which fire three. Interestingly enough, this means the Perforator follows the 1 shot for every 1.5 ratio in V.A.T.S. as well.

Like all silenced weaponry, this rifle is best used by a hard-to-detect character. A character with 100 Sneak and Chinese Stealth Armor will be virtually impossible to detect, allowing continuous fire on some targets without being detected.

Although being essentially a unique Infiltrator, the Perforator cannot be repaired by them. However the Perforator can be repaired with simple Assault Rifles.
