Tactical Solutions X-Ring takedown backpacker 10/22. This is a factory rifle in the Magpul backpacker stock. Full size pic rail, fiber optic sights and 1/2×28 threaded barrel. The charging handle is reversible for left or right side charging. The check riser opens up to store through 10rd mags. I also have the Monte Carlo style cheek riser and this comes with one 10rd mag. Super reliable and super accurate.
