Laser RCW recycler
These particular recyclers are primarily mods for the laser RCW, but are also compatible with the recharger pistol. It replenishes one shot per four rounds that the player character uses. Visually, a light gray disk-shaped object is affixed to the rear of the electron charge pack socket assembly can be seen on the laser RCW, from the point of game-play — no electron charge pack is used on every fourth shot, effectively giving you 33% more ammunition, and a 33% larger magazine capacity. No comparable visual changes are distinguishable for the recharger pistol.
This upgrade can be very expensive (depending on your barter skill and discounts), so only purchase it if you plan on using the RCW or recharger pistol enough to justify the money/ammunition saved by having this upgrade. It's useful for hardcore players, since it also means you can get more out of the ammunition you already have or have a larger amount of unlimited and weightless ammunition.
Prior to patch 18.104.22.1682, the recycler was only worth 750 caps.
