+ 1 for Daniel Defence!
I just bought a DDM4V5 after decided to buy my first AR. The reviews are overwhelmingly positive and after having held several from Colt, Bushmaster and others, I settled on the Daniel Defence. Basically at the price point that I bought mine at (1650$ I think) it was 90$ more than the Colt 6920 but had far more features such as; a very nice, slim quad rail, built in QD swivel cups at the end of the lol as well as on the rail, and a HAMMER FORGED BARREL!!
I too will say that the fit and finish was very good. The charging handle feels a bit gritty but I'm sure that will break in with time.
The only negative I found was that the trigger had a fair amount of creep, but I understand that this is normal for ARs and I've been spoiled with a Swiss Arms trigger.
Carefully consider what barrel length you want. I'm wondering if one day I will regret no having gone with the MK18.
