Cross posted to build forum as well. Figured some guys here don't go in there. Anyway:

This is part of a gigantic multi-firearm fishing expedition, have a decent summer job, want many things, can only get one.
Well, I was thinking about having Jayson at IGF put together a MP5 clone for me (so it would work), but have been now thinking about putting together a Colt System 9mm AR-15, so then I could transfer uppers, be cheaper, etc. I also want to build it, to save costs, since I'm a poor college student.

Anyway, this is what I've calculated out so far:

RRA A2 9mm Upper: $450
Rock River Arms Lower: $140
RRA parts kit $58
RRA CAR stock: $65 (I like the look)
ASA drop in mag block (Colt, modified Uzi): $150
M16 Hammer (grind off autosear notch): $13.95
Total: $876.95



It's mostly Rock River, because I hear good things, but I've never built or been involved with a build, so I don't know what else is really out there. If anybody has anyway of cutting costs, but still coming out with a quality firearm, I'd love to hear it. Thanks.

Also, any advice on SBR jobs? I think if I did this I would want to bring it down to a 10.5 inch barrel.

450 is *way* too much to pay for a rock river 9mm upper. I got my detachable carry handle upper with bolt and charging handle for 370 delivered. You might not be able to find it that low, but don't pay retail on it. Buy a dpms cast lower because you really don't need a forged lower for a 9mm carbine. Or buy an eagle arms lower from quantico if you have to have forged. Use a dpms parts kit, usually you can buy the kit with the stripped lower for less money. I paid 90 dollars for the RRA magwell adapter block. Again, don't pay retail. Buy a 9mm hammer, don't play around with m-16 parts for legal reasons, unless you are class 03. Also, don't believe peoples word on what you can and can't do to parts to make them legal. (CYA, always). I don't like pinned car stocks, so I got an a2 to use on mine. Also, don't forget to get a 9mm buffer. If you use anything longer than a car length tube, you will need a spacer to take up the extra space.

Buy mine... Cut off the bayonet lug, Silver solder on a muzzle brake and avoid the uzi mag prices, Get your lower and you are good to go. [url]http://www.ar15.com/forums/topic.html?b=7&f=22&t=166665[/url]

[size=5]RRA![/size=5] The poor man's MP5 | | | V [img]http://www.vzavenue.net/~eumenides/m16/9mmfun1.jpg[/img] I don't know where one can get a $90 genuine RRA magwell adapter and I didn't realize that $11 was too much for a very easy to load 25 round mag but I have to say that my RRA setup works pretty well when using good mags and good ammo. If you stick with a straight Colt-pattern setup, get at least one Colt mag.

It was 99.00 that I paid for it, but that was thrown in there to sweeten a deal on some other items. I went through and sent the guy a list of all of the parts he needed and what I paid for them. My uzi mags work fine for me, though maybe after (if) the ban sunsets we might be able to get ahold of some new production colt mags.

I'm planning on sticking with straight Colt. I like the whole cheap Sten mag idea, but the last shot bolt hold is something I don't like to lose. Would like to grab a Colt or two down the road. Have to eat a bunch of Ramen this winter or something. That will have to wait until after I SBR it. 9mm out of a 16 inch isn't as cool as a 10.5, imo.

On good UZI mags the follower is steel. One can spot weld a tab on the follower that will enable the "bolt hold open".

Does anybody make a 10.5 inch 9mm upper for if/when I get this into a SBR? Or would I have to buy another upper and get it turned down? I'd like to keep a 16 inch upper around, for traveling to unfriendly states (Alabama). I'm assuming I should go with KKF for a fake 9mm flash suppressor.

[blue] Colt will be only source for 10" factory barrel, as RRA only makes 16" (not doing NFA stuff), you will have to cut a 16" to the length desired.[/blue]

[blue] Wont happen legally, as the serial # is registered as a "SBR", even though it is wearing a 16" or longer barrel.[/blue]

I took a RRA 16" and cut it down. Threaded it 1/2-28 and my 92F Phantom Can is used on this upper too..... [img]http://users.zoominternet.net/~subguns/9mm.jpg[/img]

One of the dealers in shotgun news is selling SBR 9mm uppers. They look like my RRA. BTW, I have a preban upper and mag block for sale, $550 to good home. Like new.
