The unique feature of this "laser assault rifle" is the addition of a "drum", which gives this weapon its unique look, high rate of fire, and unusual name.
This drum contains a bank of 6 capacitors in a circle formation, centered around an electron charge pack (ECP). The capacitors in the drum are rotated as they fire in succession, producing a single continuous laser beam. While each capacitor is firing, the ECP is used to recharge the previously discharged capacitors.
This capacitor rotation allows the Laser RCW to operate like a multi-barreled ballistic weapon (for example, the minigun), and avoids the rate-of-fire limitations imposed by a single capacitor design. This high rate of fire restricts the Laser RCW to using only the ECP ammunition type.
With adequate Energy Weaponsskill and Strength, this weapon exhibits amazing accuracy due to a low weapons spread, making it useful for taking down enemies at almost any range. As a direct energy weapon, it has no recoil, allowing for continuous accurate fire. However, using it extensively on full-auto requires large amounts of ammunition (A partial solution to this problem is to apply the Laser RCW Recyclermodification, which recycles every fourth discharge). It also has the second lowest critical chance of any energy weapon in the entire game after the Gatling laser.
Using true iron sights can become difficult with this weapon as the bright pulse emitted when this weapon fires can easily obscure the tiny field of vision that the iron sights allow. This effect is especially pronounced in low light conditions.
