There seems to be alot of new shooter buying 223 so be aware of twist of rifiling. It can be compared to threads on a screw or bolt Im sure fellow nutters can also help.
 
You need to know what the bullet weight to be used. Lighter bullets,50-55gr, can use a slower twist like 1:12, and a heavier one, 80gr, will need a 1:7 to stabalize the bullets.
