Your main form of care for a nerf sniper will be in how you load and unload your weapon. Incorrect loading – just jamming the dart in – can actually cause the gun to jam and slowly break over time. Other things which will slow your guns firing rate are water (if it’s raining the rain can rust internal springs) and dirt (if you’re a sniper most likely you’ll be crouched and lying in dirt quite often). Cleaning dirt is fairly easy and can be done with an air compressor and a Q-Tip.
