I have a remington 700 300 whisper with a can that i have for a few yrs and its been great but now i am wanting to build a upper for my rock river. I have just ordered a barrel from Noveske and now what to know what to buy for a upper and bolt set up. there are so many to choose i am a but overwhelmed. I mostly shoot subsonic loads and want decent stuff, i dont need the most expensive but dont mind to pay for quality.

thanks for the info

also what tools will i need to asemble it?I have some ar tools now just want sure as i have never removed a barrel and gas system
