RE: Thinkin about an AR
 

I really like that idea about building my own. That thought had never even crossed my mind. Was it fairly easy to build it yerself?

RE: Thinkin about an AR
 

Theya re very easy to build. If you do build one you will have to built it on a 5.56 lower so you will be limited to which rounds you can get uppers for. The 243, 308, 300 SAUM and similar rounds use a different lower.

RE: Thinkin about an AR
 

Is there not a company that I could buy the parts so that I could piece it together myself, that way I could go ahead and get it chambered in a .308?

RE: Thinkin about an AR
 

Not for anything that dosnt use a true 5.56 lower. Anything chambered for large rounds are made different by every company and 95% of aftermarket parts for AR15's wont fit.

Thanks for that little tid bit Retaks, I was already looking into mixing and matching the uppers and lowers so I could build my own .308. But now that I know it most likely won't fit, I won't waste my time and money. Thanks again.

RE: Thinkin about an AR
 

Here is a good list of what can be on an actual AR15 lower. All of these you could buy a parts set for the lower and buy an upper with this chamber. Any other round would not be an actual AR15. It would just eb an AR style rifle and most parts would not fit it.
