This RAP4 (Umarex) RAM P99 .43 Caliber paintball and rubber ball shooting Walterh P99 copy is very much a replica and looks almost bang on to the real Walther P99 with the exception of the CO2 tube that protrudes out of the bottom of the handle just a bit. Even the barrel is large diameter for the .43 caliber rounds that it shoots. The RAM P99 has very good kick and seems to operate much like my other blowback air pistols.
