This is my Remedy Metal Longshot. It's a full Remedy Metal internal kit, with a spring load of ~20kg (44lbs). I've also reinforced the trigger with a cut down 14g bicycle spoke glued in to the groove on each side. Priming handle is Xplorer grip, sights are Slydev 3d printed and all locks have been removed. Clocked at 197fps using aftermarket heavy silicon tip darts. I'm pretty sure If I can manage to make a lighter plunger and plunger rod and maybe a slightly longer barrel, it will crack well over 200fps, a stainless steel plunger and rod with a tight fitting o-ring really isn't the best for performance.
