However, the more basic weapon, the M41-A Pulse Rifle, has a channel down the top of the shroud that acts as a set of iron sights note though that Ripley's famous pulse rifle with a flamethrower duct-taped to the side of it has a locator also duct-taped to the carry handle, obscuring the sights. The Smart-Guns from Aliens have computer assisted aiming, and don't need iron sights.
