Has anyone built a AR 15 in 243 Win.

Been out of the game for several years. And have started building a few 5.56 kits, but when a did a lot of hunting the 243 was my favorite cal. I saw in the Shot Gun News that Olympic Arms Inc. offers a 243 upper. I was wondering would you have to use a 308 lower and also the 308 mags?
It is my personal opion that the 243 AR would be a real good rifle. I would like to hear from you all, pros and cons.
Thanks

The only Olympic 243 upper I've seen was the 243 SSM. I've been tempted to get one as well, but for the cost I'd rather throw that money into an AR10 platform and build one in 243 Win.

Moleman, Thanks for the info. Like i said, i have been out of the game, where would be the best place to read up about the AR 10 system?
Thanks

DPMS, Armalite, Stoner, Remington and others make ar10's which operate just like the ar15's.

I will do a google search and look up the AR 10. I am still trying to figure out the M4, from what I can tell it uses a piston system like the AK? But untill I can get my hands on one to see it, or a drawing that will so me the perpestive.
Thanks

There are some companies making ar15's/m4's with a gas piston set up, direct impingement is still the standard gas system.

Been doing a little searching on the AR 10, but havn't found out much. Can you tell me what the differnce is between the AR15 and the AR10?
Thanks

The ar10 is a 7.62x51/308 sized action, the ar15 is a 5.56/223 sized action.

the link has a bunch of 308 type ar-15 parts, uppers, bolts and so on.

the 243 will require the larger AR-10 type framed parts.

ever consider building a 7.62x39 ar-15 though? -- much fun to shoot--

Thanks guys! I am not fond of the 7.62x39, good cartidge in a short AR or AK. I want something that will reach out there a little ways. I believe if I get some of my other guns sold I am going to build a 243WSSM. I looked the balistics up on that cartidge and I think it will work good for what I want.
Thanks
