We put Ruger ranch 6.5 Grendel in mdt lss-xl gen2 chassis, strike industries buffer tube, Magpul ctr butt stock, magpul moe-k grip, removed rail for Talley 1” low lightweight rings, trijicon accupoint 3-9x40 green dot. About 8 1/4 lbs, launches black 123 eldm at 2386 fps, 6.5 ft/lbs recoil energy and watch everything in scope. Kids started off awesome with this set up. Black bears and deer 10-355 yards. I’ve used it for more than that and up to 420 yards. Adjustable lop. Great set up. Weight is a good thing.
