Concentrated Fire

Concentrated Fire is a Fallout 3, Fallout: New Vegas and Fallout 4 perk.

Fallout 3 and Fallout: New Vegas
Each successive time you target the same body part in V.A.T.S., your chance-to-hit raises by +5%. So, if your first to-hit was 40%, 2nd would be 45%, 50%, etc. This can lead to very easy head-shots when teamed with other to-hit % boosters (Sniper, Commando, etc.)

Bugs
In Fallout 4, the second rank of this perk does not work, although the first and third ranks do.
 * This is caused by the second rank incorrectly affecting the V.A.T.S. damage by 15% similar to rank 3 of the perk.
 * In Fallout: New Vegas the Ultimate Edition, if one has enough points in a skill, then on level up place enough to get the perk, one can go back and remove them from that skill and put it in another, still getting the perk that is grayed out by selecting done.
