| Is there a site i can go to for information on building a 9mm AR? If so what are the recommended parts manufacturers for building it as a high quality firarm? |

Well, you found it!!! [:D] There isn't that much difference in the 9mm vs 223 AR. To sum it up, a 223 lower will fuction fine w/ a 9mm upper. IF you have the "compatible" hammer. This link shows the most common questions on the 9mm: [url]http://www.ar15.com/forums/topic.html?b=3&f=15&t=108261[/url] I suggest reading Hammers: This pic shows a 223 hammer that WILL work with a 9mm upper. [img]http://www.biggerhammer.net/ar15/hammers/ar15_early.gif[/img] Below is a picture of a hammer that WILL NOT work. The difference is that little notch in the front. If you get a hammer w/ the notch, it will lock up the bolt if used w/ a 9mm set up. [img]http://www.biggerhammer.net/ar15/hammers/ar15_std.gif[/img] A simple solution is just to grind the head round.... If you read throught the post, you might have ran accross "bolt ramping". Don't worry about this, yet..... I have a 9mm set up from ASA on a Cavalry Arms lower. My Cav Arms lower (plastic) was built as a 223 lower (has the 223 buffer and spring). The hammer installed is the "compatible" one. All I did was install the magazine block adapter and put the upper on and it was ready to go. Parts: Magazine conversion block [img]http://www.rockriverarms.com/images/9part2.gif[/img] Center item. This example is from Rock River Arms and costs 150.00 [img]http://www.rockriverarms.com/images/9mag.gif[/img] Magazine. See notch near top... that is needed to work w/ the AR. Standard Uzi mags don't have that notch.... Notched mag suggested retail 35.00 [img]http://www.rockriverarms.com/images/9ua2.gif[/img] Upper...suggested retail: 450 I can't recall off the top of my head of RRA offers a 9mm "kit" to assemble. Example if you were to "piece" a kit together- lower: 100-125 lower parts: 50-60 butt stock kit: 60 upper: 450 adapter block: 150 mag: 35 total: 845-860 now, that is on the "high" side. There are dealers (aka Industry partners) and sellers (look in Equipment exchange) that sell Rock River Arms stuff. I suggest a Rock River Arms 9mm set up. A lot of people like the RRA vs the ASA (as the ASA upper receiver looks "cheesy", my opinion). Hope this helps. |

Some more info.... Aside from "Colt style" (RRA and ASA are this style), you have Olympic Arms and their verison of pistol cal uppers. Their 9mm uses a modifed Sten mag. It has a extention welded on to it that the notch for the 223 mag catch "holds on to". Modified mags typically run 50-65.00. The Socom mag block (about 60.00) can be used.... held in place w/ the 223 catch and a paddle release holds the Sten mag in place. A benifit of the Oly is, it will work on a 223 lower w/ any hammer. An upper from Oly runs suggested retail about 600ish... Both systems work. I am biased since I have worked w/ the Colt style (owning an ASA). I have no experiance w/ the Oly pistol cal style. |
