The Tactical Innovations® Elite22TD Takedown Flat Top Receiver is designed for customers that want a billet takedown 10/22® compatible receiver in a flat top configuration without a rail while still having the ability to add a bolt on zero MOA machined picatinny bolt on rail of the same or an alternate color. This receiver without an integral picatinny rail will often work with many chassis systems that are currently on the market (although we don't have a list of which work and which don't). For a quality build and optimal compatibility, we recommend and proudly stock Pike Arms® match grade parts and accessories.
