AR Gurus please help a newbie to black rifles

[shootindude]

Ok so my buddy gave me some parts for switching over his noveske lower and pws setup for him.

He gave me a superior arms lower, stripped. A giselle trigger, a couple of trigger guards, ambi safety, and all the misc little pins to make the lower a complete minus stock and grip.
I really want to build a nice ar but not in a 223 caliber though. Im wondering what is possible though on a 223 lower. I think the 22 250, 243 etc.. will work, but was wondering if anyone had a site or something that would give that information.

Any help would be greatly appreciated, i'm not a total newbie so please dont kill me for the ignorant post, Im just new to the AR scene and after going through this website for quite awhile i decided to register, plus i never knew AR-15s were so accurate until i read up on them on here. Thanks guys

check out dpms website it pretty well lays out what calibers can be used with the ar15 lower and which for the ar10 style lower.

looks like 204, 223, 556x45, 6.8x43, 7.62x39.
243 and 22-250 are large cases ala ar10

Ok awesome, thank you for the quick response, One other question. I have access to a bead blaster at work that we blast titanium parts with. Has anyone bead blasted a lower? Will it chew the aluminum up too much to safely do? I will probably just mic out a trigger guard and blast just that part and see what it does. Thanks though in advance

Ok looks like the 6.5 grendel is available also for my selection. So heres a thought, 6.5 necked to 6mm for the 6mm rat or turbo. Ill do some more research and let ya guys know what i decide.

I picked up a lot of info on this thread.

As a side note I stumbled onto a forum talking of AR 15 ,M 4 zeroing.
Wow,I did not remember any of what I read except the term BSZ...
And I am almost convinced in buying a set up my self
Good luck with your build.
ps
Barrel type and twist seemed all important on any caliber selected.
