You ask questions that...
When the messiah comes he will tell us all we need to know. The reason is the placement on the frame of the M203 grenade launcher. I just know the full size 20" barrel is good to go, but in order to sling one on the 16" barrel you have to have the step. I wish I could be more specific.norfdet wrote:why does an M4 have a step in the barrel but a full size rifle does not?

The Short Answer
There is a very and I mean very slight difference in the throat and neck of the brass. But the biggest difference is the thickness in the brass. The 5.56 brass is a tad thicker thus causing higher pressures in the chamber. The rule of thumb if your rifle is marked 5.56 you can shoot either round since the chambers on the 5.56 rifles are a little rommier. If the rifle is marked 223 you should only shoot 223.
Now for the long version and I mean long version click here:

Oly M4
Nope, Oly does not use Chromed Lined barrels. Which is fine you only need that is you are shooting full auto. Also I will be getting some more M4A3s in a couple of weeks. They will be shipping in the begining of the next week.norfdet wrote:Scott,
the Olympic Arms M4's that I looked at last night, did they have a chromed lined barrel or not?
Stupid question time;
If you do not have a chromed line barrel is there a certain break-in peroid that you have to do when you first shoot the rifle? I reference the suggested Kel-Tec SU16 break-in, which is to shoot the rifle (a few rounds) and clean the barrel, then shoot it some more repeating the process a certain number of times.

Break it in...
Sure this is how I did it. Shoot a 100 rounds, take a bore snake and run it, and clean the chamber out and shoot on till you are sore in your trigger finger.norfdet wrote:Stupid question time;
