Good luck with your purchase.
Just remember to get the platform you want for future expansion. I got the 223 because of the cheap ammo for plinking and varminting, but I am expanding to the 243 WSSM for bigger game.
I could also go with the 6.8 spc or the 7.62 x 39 if I want with this 223 lower.
If you want to go bigger you have to go with an AR10 Lower platform for some of the bigger [Longer] ammo.
