Newbie to AR-15 .... Additional Upper
Two weeks ago I picked up my first black rifle, a S&W MP15, in 5.56. I added an Eotech scope and have been to the range once. ^_^ That was a lot of fun.
Unfortunately, it did happen. I contracted the disease, and now I have the fever to get another AR. I want another caliber with some more "punch." Here's my question: I was browsing through some sites and read a post that implied I could get a second upper in a different caliber (eg, 6.5 Grendel) and I'll be able to slap that on my lower (even though it's stamped "5.56"). Is that true ? If it is, are there limits to what caliber of upper I can get to mate with my 5.56 lower? As always, thanks for all your advices.

You are limited by the dimensions of the magazine well for instance .308 will not fit in the 5.56 mag well you would need an AR-10 style Lower for larger alternate calibers.
There are a number of alternate calibers that will function through the 5.56 lower given the appropriate magazines, bolt group and barreled upper. |

There are definately limits - I have a DPMS AR-15, and I know that they offer a 204 ruger, a 6.8SPC, and a 7.62x39. You cannot grab a .308 upper and just slap it on there.
I'm sure there are several others that are available, but those are the three that I know should "drop in" on a AR-15 lower. |

I knew I could count on TFL guys/gals !
Wow, in about 10mins or so I have 3 very good responses. Thanks !
I'll search for that thread referencing what calibers are compatible in a ar15 lower to give me options for additional uppers. New question: My magazines are 5.56/223. Will I need to get caliber-specific magazines, or will the 6.5 Grendel or other similar calibers rounds fit in my existing magazines ?

IZ - thanks for your advice
Any recommendations for on-line sites where I can order the new upper? Del-Ton, Bravo Company are two sites I'm reviewing.
again, thanks for your help
