Im new to this and wanting to move away from constantly borrowing mates guns. Looking at a GBB pistol. Mate uses Raven EU17 series 4 which feels good however also looking at WE EU17 Series 5 which is only £40 more. Found lots of comparisons about WE EU17 and the Umarex EU17 however can't see find any differences between the RAVEN S4 and the WE S5 Any help appreciated.
