Just received a very nice and complete FWB300S Universal v1; High & standard cheekpieces, high front sight and rear sight riser, recoil pad spacer, extra grip caps, sticker, cloth patch, disassembly tool, targets, pellets & original manual.
I would think that reticle would be unique! I could see how you could use the distance between the posts to judge your lead on a moving target. You couldn’t use it for anything else!
