So I just got my hands on a brand new Gspec for relatively cheap. Seeing that this is my second bolt action I'm building I kind of know what I'm doing (internally). But since its a shorter rifle, I honestly don't know if I should go with a high fps or more of a mid range fps rifle. Also I'm sure this question is asked a billion and one times, but which barrel length should I go with and which company? I have about $500 to play with, but obviously I don't want to spend ALL $500. I hear Laylax and PDI are the "best" when it comes to internals, can someone give me some options/opinions on which to buy?
