Looks like I am going to purchase my first AR (6400C). However, I have some simple questions that some of you guys may be able to help me out with. Is the 6400C 5.56 or .223? If it is .223 does this mean I can't use Q3131A and XM193? What does the US military use in their 1/7 twist M4s and would be able to get this ammo on the civilian market? If not what is the closest thing? Last but not least is there a real argument not to purchase the colt vs. another brand AR in this configuration. To me it seems the Colts are hard to find in the St.Louis area is there a particular reason for this? I would appreciate any input.

Having a .223 rifle does not necesarily mean you can't use 5.56mm ammo. A lot of people do and have no problems. If a problem occurs, it will most likely be a feeding or extraction problem. The military uses M855/SS109 type ammunition in the 1/7 twist barrels. Yes, it is available for civilian sales. The 6400 is one of the few Colts I would reccommend. It is the crown jewel in their civilian line-up. A Bushmaster would be the only real competition to the 6400, but the 6400 comes with a lot of features that would take extra money and effort to make a Bushy M4 similar. Colts are pretty hard to find in most areas. Civilian sales are a low priority with Colt these days. The only real concern is the good possibility that Colt's customer service will be quite lacking in the case that you have a problem. That is not always the case, but sems to be a lot of the time. However, the good news is that the 6400 seems to be the model with the least problems in Colt's product line.

I bought one of these about six weeks ago. Just for grins I temporaly put a Leupold 6-24X50 long range on it to check its accuracy. I found several loads that were sub MOA. I did not expect this from an M4. I only have 550 rounds through it but it has been 100% reliable.
