Welcome to the clan, Sk, from the great nation of Texas! You don't state whether you wanna role your own or buy a ready made upper. There is a wealth of information across these threads about both. If you choose to build one, the core of the success is in the barrel selection and then the assembly methodologies. The Grendel is capable of incredeble accuracy when built with care. And, in case you haven't seen it across these chapters, be forwarned! The Grendel is a prolific little beast and, when left alone will multiply rather quickly.
