Anyone build one of these yet? Is there any uppers out there already machined and ready to go? Any tips on a build? Any feed issues? Thank you in advance.

I have one.

No feed issues. The only drawback is there is no bolt hold open.

There is a spec sheet on CMMG's website for the mod to the upper. There are a few uppers that are already modded, but they sell them as a kit (upper and lower) and they usually expensive.

SI Defense (http://shop.si-defense.com/ProductDetails.asp?ProductCode=SI%20308%20MS-G3) has one for $725

I think someone ese made a matched set as well. I have never seen a G3 AR308 upper sold "a la carte".

PM me if you're interested in a DPMS upper, milled for a G3 lower... reasonably priced ;) ( ETA- Not my built rifle. I love it, and it isn't for sale. I was refering to a spare upper receiver I have.)
