Ive been looking for one for several years, I did find one lesser known company that was selling an upper for about $650. Sorry but I cant remember the company name. They were selling 20 round mags with the welded on conversion so they would fit into the standard magwell. This was well after the AWB and they wanted something like $79 bucks a piece for the mag, needless to say I passed on the idea. Im still waiting for someone to make a reasonably priced upper and some less expensive magazines. |

I think Oly is the only ones making them at the moment. MGI will probably add it to the queue of calibers they are making for their modular lower/ CQB upper system ar15.com/forums/topic.html?b=7&f=125&t=321244 |

I have a Oly 10mm upper, using modified GG mags with a Cav Arms lower/Hahn mag block, and it works flawlessly. I am also currently putting together a Colt-style .40S&W upper using UZI .41AE mags, a modified Colt 1-piece block, and a Colt bolt with the bolt face opened up. The UZI mags are hard to find now, but Sten mags may work with an adapter. Also, colt barrels are easy to make. There are several folks who could do one up for you in .40S&W. |
To bad I'm in GA. I plan to be in Reno in December, that the story of my life. Wrong place at the wrong time. I'll keep a watch on that RRA plan. That would be perfect. |
| You may want to try to find out the optimum barrel length for 40SW. A 16" barrel actually has less velocity than a standard pistol barrel. After a certain length the gases aren't expanding enough to overcome the barrels grip on the bullet and the velocity begins to decrease. This is the reason I lost interest in pistol caliber carbines. |
details on the mag please. Round count and manufacturer? ETA: Awesome! About time one of the big boys decided to make a .40. |
