Trying to piece-meal a precision rifle really doesn't work. You wind up spending more money and have less performance than if you would have saved-up and purchased a "complete" rifle.
Eh, that's kind of a generalization on everyone else's skill set isn't it?
I didn't start building AK's just to save money (although I have saved a lot of money doing so at this point), I started building AK's because I like the satisfaction of doing something myself and I love projects. I heard a lot of naysayers when I started building, a lot of, "Why don't you just go out and buy a WASR? It'll cost less and probably work better". I thank God I didn't listen. Same thing with AR's. Same thing with modifications to my pistols ("Why don't you just pay a gunsmith to work on your 1911's trigger?")
Currently, I have a money pit bolt-action that I'm slowly doing small things on. Yeah, I could just go out and buy an FN SPR and be done with it, but I like the journey. I have a good time planning out the project and doing my own glass bedding and installing ceramic pillars and deciding how thick of a barrel I want and should I change the caliber and what kind of scope and what kind of mount etc etc etc... I could never have this much fun if I just saved up and purchased an FN SPR or something similar.
But I'm mechanically minded and not everyone is. For some people, purchasing the rifle they want instead of building one up is aok. Myself, I'd rather have a good DIY project.
If someone is of sufficient skill-level to build a true "precision" rifle, I doubt that they are going to start with putting a sniper stock on a Remington 710. If you had read my previous posts, I stated that starting from a receiver, barreling the action, etc. etc. is not "piece mealing". It is building a rifle with proper planning from the outset.
If you want to build a precision rifle, the Remington 710 is not best action to start out with. I don't think you'll find any skilled gunsmith (particularly not any known for building precision rifles) that would recommend you put additional money into a Remington 710; they will tell you to purchase a new/used Remington 700, Savage 110, Winchester Model 70, or any one of a myriad of other actions.
If he is interested in learning the process for working on his own firearms, fantastic. Again, the Remington 710 is not the rifle to use. For one thing, you can't rebarrell the thing. No need for further discussion. I don't see a point in learning "how to gunsmith" on a rifle that really wasn't intended to to "customized" in any way.
I'm not knocking the Remington 710, or questioning the poster's decision to purchase one. I am stating that if he is looking for a precision rifle, the Remington 710 is not going to fulfill that role and it is not logical for him to spend money trying to do so.
If he is looking to learn more about working-on/accurizing rifles, the Remington 710 is again not the proper choice.
