Nothing's better than seeing that surprised look on your target's face. The Loophole x20 Scope on this hunting rifle makes it easier than ever before. Accurate from first shot to last, no matter what kind of game you're gunning for.
The scope on the weapon dramatically increases the weapon's accuracy at range, allowing one to reach 95% accuracy at long range even with a relatively low skill. It has a drawback, however, as once the distance to the target gets below 8 meters, the aiming accuracy receives a huge penalty, rendering this weapon almost useless at close range, even with a high Small Guns skill.
One can be obtained from a quest in Broken Hills, given by Marcus if one chooses not to take the money at the end of the quest.
Skeeter in Gecko, Eldridge and Algernon in New Reno can all upgrade a normal hunting rifle. This is also the only weapon that Buster in NCR can upgrade. Strangely, Valerie in Vault City cannot upgrade it for some reason.
