Jury Rigging Jury Rigging is a in " " . Effect . With this perk , one can repair items based on category instead of type . For example , the rare Ranger Sequoia can be repaired with the common . 357 Magnum revolver . The same goes for . There are 13 categories of that the perk will enable repairing within : unarmed , one - handed melee , two - handed melee , energy pistols , energy rifles ( laser ) , energy rifles ( other ) , energy weapons ( heavy ) , one - handed guns , two - handed automatic guns , bolt / lever - action guns , miniguns , grenade launchers and missile launchers . Likewise , clothing can be used to repair each other within their category ( light , medium , heavy ) . Finally , almost all headgear can be repaired with any other headgear . Weapons are categorized , to some extent , by the method in which they are fired . For example , the bolt - action anti - materiel rifle can not be repaired by a because the sniper rifle is a semi - automatic firearm , but it can be repaired by the as it is also a bolt - action weapon . However , some discrepancies arise with other weapons . For example , the 12 . 7mm SMG is categorized as a two - handed gun and therefore can not be repaired by the and SMGs , since they are one - handed guns . A mostly complete list of all weapons that fall into specific categories can be found below . A simple way to tell what weapons can repair each other is to look at the way that the player holds the weapon , in addition to the general type of the weapon ( Guns , Energy , Explosives , etc . ) . For example ; as the player holds the in the same way that they hold the laser RCW , Jury Rigging lets the player repair them with each other , even though one is laser and one is plasma . However , since the is held differently ( more like a bolt / lever action gun ) , one cannot use it to repair the laser RCW , nor vice versa . This perk reduces the need to effect repairs using weapon repair kit s or non - player characters . It also allows the player ' s character to reliably repair their weapons with similar , much cheaper ones from fallen foes after or during combat without having to seek out an exact match . Characters who use low - durability weapons and picked the Built to Destroy trait , or find themselves using surplus or over / max - charged ammunition often reap greater benefits from the perk . It can also be a big help to those who favor certain unique weapons like the YCS / 186 or Oh , Baby ! , whose normal repair counterparts are rare or expensive , or weapons that do not have a standard repair counterpart ( like the X - 2 antenna , which is a completely unique weapon ) . This goes for armor , as well , meaning that even Remnants power armor can be maintained on the cheap with a set of . Repair categories . Each weapon and armor falls under a specific category in which all weapons / armors repair each other . Weapons . Weapons are listed by their base variants and in alphabetical order , except in cases when it is unique . Two - handed melee . The throwing knife spear can be used to repair the knife spear , but not other two - handed melee weapons . The proton throwing axe can be used to repair the proton axe , but not other two - handed melee weapons . The throwing spear can be used to repair pool cues , but not other two - handed melee weapons . Energy rifles ( other ) . Note : The can also be used to repair the recharger rifle . Unaffected weapons . Each of these weapons is in its own category and can only be repaired by a copy of itself , its unique variants or a weapon repair kit .
