I have always wanted a CC C8CQB for my CC collection. I have seen one on the EE but just didn’t have the means to purchase it from the member here, so I am going to build one. Parts I am going to need will be upper receiver, barrel assembly, BCG, CH and furniture. I see the hardest parts to acquire will be upper and barrel assy. Well last night I received one of those pieces. A CC stripped upper has now been added to my collection thanks to NMI. Since a CC CQB barrel will be next to impossible to find I have been looking at the DD 10.3 with FSB. Here in lays the problem. The CC upper does not have M4 cuts (I think it is a C7 upper) and the DD barrel uses A4 (enhanced M4) cuts. I know that M4 barrel to standard upper is “ok” but my OCD is not happy with me. I don’t know if I should consider a different stripped upper with M4 cuts and sell the CC or just build it anyways. Help me please with opinions, if you have OCD when building you will understand why I am racking my brain.
Side note: If anyone has a C8CQB upper, I have the Danish and this stripped upper plus cash to trade.
