KrissYou can also build one from EE parts, I have, easy to do and I am not very handy. I would go 9mm for cost/close distance shooting and .223 if you want to stretch it more. Barrel 10.5-14.5 have universal appeal (i have 7.5"-16" in 3 cals). Building is fun and allows for you to get exactly what you want. Cost wise vs the exchange it is about the same but getting exactly what you want and put together with your own hands is the big plus.
I recall you getting my Bushmaster 9mm for a fair price if this is the same person and there was some re building to do there (if not the same buyer my mistake).
You are correct though, I did source another 9mm for a good price on the EE, when cost of ammo is factored 9mm pays for itself even with the added build costs compared to .223
I have a lower I want to build a 300BLK
I have a ton of 208g AMAX Bullets that would be fun to shoot
