Good morning, hope all had as good a Christmas as I did.
I picked up a slightly used (150 rounds) Colt MT6700 for Christmas. Does this rifle have the chrome lined barrel and chamber? The barrel is marked C MP / 5.56/NATO 1-9.
I know the 1-9 is the twist rate and the 5.56 tells me that it's a military spec chamber and so I can use civ .223 or mil-spec such as xm193 / m855 etc.
To this point I've put 120 rounds through it getting it zeroed and seeing what kind of 3 shot groups I could get at 100yds. Best to this point is right at 1.5in. I am not a complete newb to the AR series of rifles having spent 12 years in the Army but I do realize that what we had (M-16A1 in Germany, M-16A2 when we deployed to the sandbox and then M4A1 when I was sent to Bragg as part of SOCOM) isn't quite the same as the civilian counterparts.
Thanks for the help guys!!!
