If it is a short action then it will fit the 223. It is just that the follower may be cut to fit 308 win sized shells (Diameter .473") that is the 22-250, and all the 308 cousins that were made off of it. You might just need to replace the follower with one made for a 223. You might be able to modify a stock Remington 223 follower to fit the mag.
