I'm asking if shooting a .308 out of a designated 7.62x51 barrel and vise versa would effect the accuracy past a certain yardage or are they basically the same round. I understand that 5.56 is a hotter round than a .223, but the bullet size is the same as an example.

Would the accuracy be the same, or would it only matter past a certain point?

Thank you for clarifying, so can I shoot both out of the 7.62 noveske barrels without consequences.

so... 5.56 is .223 as .7.62x39 is .308?? does that make sense what im asking?

I thought that 7.62x54 is in some way different than .308.

Are the mega uppers compatible or just an armalite? Also I kinda don't want a Noveske barrel because they don't make .308s. I mean sure I could shoot .308 out of an 7.62x54 but I don't know just not being able to say "Yeah its 308 it's pretty sweet" would suck. I guess I could grab the lower and just recoup some money. But damn that's a lot of cash for just a lower. I could get a mega lower/upper combo for that. I mean everyone says they make a good product but is it 700$ lower good? I know it's my decision and I'm just ranting but if you really wanted a lower from a company that didn't make the product abymore and has to pay a premium for would you do it? Or would you go with anothwr company for that caliber and go with Noveske for a different caliber? Man this is a blunder I don't know what to do.

I mean I found 1 for 700$ but that's a little to rich for my blood. I mean just for a lower anyways.

Well I've pretty much givin upup any hope of noveske for parts. Maybe when it comes time to build 5.56 rig. But for now I think I'm gonna go with a Mega Maten upper and lower. As far as distance and it will be a 600yards target beast my budget is about 2500 or a little more if needed. I know I can pretty much achieve this with a 5.56 build but that would be no where's as bada** or what I want. I don't know what to pick for a barrel either, I've heard good things about the ultramatch series but its going to be a 20 or 24 barrel and those don't look all that great. Remember this is going to be a dream build and appearance is just as important as functionality. So please if you have a humble opinion share, if you are going to try to pursuade me into a 5.56 please move onto a different thread.

I am completely new to the concept of building an AR. I have tried doing some research on noveske lowers, but they all add up to the N6 lower which if I'm right they don't make anymore. I want to build a precision rifle, that being said Noveske seems to be the company that offers that. Is there a new lower they offer in 308? I also understand that only Armalite and Noveske uppers are the only compatible uppers. Are larue or lewis machine and tool lowers compatible with a Noveske upper? Any knowledge would be appreciated as I am new to this and all the compatibility problems are overwhelming. I want this to be a dream build as it is my first and probably my only for some time to come. Thanks
