*if you don't care for the story aspect and only want to help me with the build, just skip to the bottom asterisks ****** Before you guys make fun of me for not knowing the correct terms or not searching other builds. I'll be the first to admit I don't know a lot about building a rifle. But I'm learning as I go (with my 5.56). So bare with me. So to explain a little how this rifle is going to be important to me, and not just some rifle I'm building, let me explain... I was talking to my dad (who I'm not as close to as my mother) that I wanted to build something to will last a long while and it will be something we can do and use together. So for the past few years my grandfather has progressively been getting sicker and sicker. I know he is getting old and he just recently had a pretty bad hear attack(after two previous attacks). We are honestly not sure how much more time he has let with us. Similar to my dad, I don't want to lose my grandpa and not have anything to remember him by. So my dad, grandpa and I talked and we decided to build (or better yet piece together) a rifle. This wont be completed any time soon but I want to get my grandpa involved so it will be our thing. ******So on to the rifle. We have decided to build a AR10, or 7.62/.308 AR (or whatever you call it). So what I'm looking for are some quality parts. What I should consider and what I shouldn't. What parts work and which ones don't. I know the selection of .308 parts aren't as available as the AR15 so that's why I ask you all. What the rifle will be used for: very occasional long range shooting Maybe hunting (probably not so much) Mainly something to remember my dad and grandpa I only know of a few different companies that sell parts but I'm not looking for a budget build. So we are open to all suggestions. We don't plan on buying a complete rifle. Basically what I'm asking is to help point me in the right direction. If you have questions to help direct me better then please ask.
