First time forum member.. Attempting first AR-10 build.. Help appreciated

[jcalveri]

I recently purchased a complete Armalite lower from their website ( http://www.armalite.com/ItemForm.aspx?item=L10PCB&Category=8780cda4-b901-4b0c-bc96-d7c6ca2b924a ) .. I would gladly purchase a complete Armalite upper or a stripped one and go from there.. But I was wondering (because I've heard in a few different places that some other uppers are compatible) if any other uppers (Noveske, CMMG, ASA, POF, etc..) would fit and be compatible with my Armalite lower. If any are, which are they, and if not, would it matter what Armalite upper I got for it? Or could I pick any of them from the Armalite website? I want a 24" stainless / heavy barrel, and I want to be able to put a nice bipod on the handguard. Being pretty new to AR builds in general, I could use all the help and suggestions I can get.. Thanks for reading guys, and God bless!

The upper receiver needs to be Armalite-compatible.  If a company that you're looking at makes DPMS-based 308s, then fitment of that upper becomes the issue, when attaching it to an Armalite lower.

Welcome, to be specific, to my knowledge the only other compatible receiver is noveske  <thumbsup>

Mega MA-TEN upper and KAC upper will fit, also.  <thumbsup>

I'm not sure if the Armalite mags will function with those two, though.  Expensive experiment, unless you can find confirmation somewhere... 

Edit - Iron Ridge used to make an Armalite-pattern set, but I don't know if they're still doing that anymore...
