Pulled the Trigger & Ordered one of the CMMG M4 (style) rifles. Got it last week.
CMMG Lower Receiver + Upper with Square Symbol (Brass Aluminum Forging Enterprises?). The Black paint on the lower & the upper slightly don't match, but you have to look hard to notice. No exterior scratches and everything looks new. Breaking it down, I did notice some wear in the chamber area where the bolt face enters, but only from slight use. Overall, I'm pretty happy with it. Looks and feels about the same as my duty M4 (except the CMMG barrel's a bit longer). Plan on shooting both tomorrow to compare.
Rifle - $600
"Hand Pick" upsale - $25
Shipping - $25
FFL Holder Transfer Fee - $30
Total Cost - $680 (ish).
Now I have to troll this thread for a good deal on a scope/sight.
