New to the world of AR...
I have an AR10A4 by Armalite to fire the .308/7.62x51. Recently I was looking at purchasing a Hi-Point .40cal Carbine to go along with my Hi-Point 995. While browsing, I stumbled upon a site that had a heading: "Olympic AR-15 A3 Flattop Upper Assembly 9mm". In the details it went on to say "The 16" button rifled barrel is chambered for 9mm Luger and has a 1 in 16" rate of twist. Ready for installation onto any standard AR-15 lower receiver."
My question has now become; 'Will the upper assembly for the Olympic AR-15 fit the lower assembly of my AR10A4?' It would be great if all I had to purchase for ammo was .40, 9mm for target shooting and the .308 for hunting. Any advise or help would be great. Thanks. article ref: http://www.midwayusa.com/viewProduct...tnumber=924841 |

Sorry to disapoint you, but I believe the 9mm upper will need an AR-15 lower not a AR-10 lower.

So to further flaunt my ignorance... what are the major differences between ARs 15 and 10, other than incompatability?

Now, the main difference between an AR-15 and and AR-10 are size. The 10 is bigger to allow for the bigger magazines that hold the bigger/longer cartridges of the .308 based family. The 15 is smaller allowing use of the smaller/shorter .223 and other cartridges whose length is equal to or less than (with adapters for magazines) that of the .223... Other than that, everything between the 2 is the same, just in different scale...

But yes, the main difference between AR-15 and AR-15 lowers is the magwell size. There may be a few differences in the parts kits as well; I'm not terribly familiar with the AR-10 design, but the LPKs are different between the two (and I couldn't say exactly what the differences are). Furthermore, the 9mm top ends sometimes require more than just a mag block and a buffer change; depending on the design of the thing a new hammer may be required as well (there's some 9mm uppers out there that will work fine with a regular AR-15 hammer). Rock River also makes a 9mm upper, but I couldn't tell you if it's one of those that requires a special hammer or now. |

If your really interested in a pistol caliber AR15 look at stuff from Ron Williams, Bazooka Bros. or Olympic Arms. I'm looking at the blow back .45acp from Oly. A 11.5 barrel with a can sounds like fun to me.
