Feed ramp

Feed ramp is a basic feature of many breech loading cartridge firearm designs. It is a tightly machined and polished piece of metal which guides the cartridge at the top of the magazine into the firing chamber of the barrel. Depending on design, the feed ramp may be part of the magazine (AR-7), part of the receiver or frame (Mauser C96), or part of the barrel (H&K USP). However, some firearms, like the FN Five-seven, have a beveled chamber instead of a feed ramp.
