Strike Planet walks us through the feature of the "Stilleto" launcher made by StrikeArt for airsoft and milsim use... " The product allows you to turn any airsoft underbarrel grenade launcher with a picatinny rail mount into an independent weapon. The base is a steel frame with a folding stock and a folding rib. At the bottom of the frame is a pistol grip and a mounting plate for fixing the grenade launcher. The product weighs 830 grams, shooting can be carried out both with the stock unfolded and with the butt folded."
