I usually hang out in the retro section of the tech forums. A coworker wants to buy a rifle of mine, and I want to apply those funds to a Colt 6450. If he does not buy my rifle, is it going to be a nightmare messing with conversion blocks and the like converting my old rifle to 9mm or would it be better to sit it in the corner and get a factory made? I have a dedicated polymer .22 I pieced together and love it, and I have several 5.56 rifles already. I have the 9mm bug now.

I don't know about convert your own vs. factory made.



I do know my Colt 6951 (flattop with a matech flip-up) is reliable and great fun.

It was $1075 at DSG.



It seemed like building one from scratch was going to cost almost as much as buying a Colt.

I was asking the armorer at work what he thought about it. All we use here are Colt 6721's. He did pull out a full length A2 9mm upper with 2 funky magazines. It has OA stamped which I'm pretty sure means Olympic. He told me he didn't have an opinion on them cause he's never used one, but I could sign this out an play with it to see if I Iike it.

Edited for spelling, typing on android.

Right now, I would bite the bullet and buy the 9mm parts and do a seperate build or buy the factory colt you want.

If the election goes one way, parts may spike up in price and not come down to reality for a while.  You can at least get the important Colt parts as a start.  

HK parts has some SMG kits: http://www.hkparts.net/shop/pc/Colt-9mm-SMG-Parts-Kit-Used-p841.htm

Looking at those prices for kits, I'll buy a factory rifle. The only reason I was contemplating converting the other one is that selling the retro parts would offset the cost of the 9mm stuff., and i'd wouldn't be coming out of pocket too much to complete it.

I ended up getting a slightly used Colt 9mm instead of making one up from kit of parts.

Check out RMW Xtreme's 9mm. It's reality now. Check the lack of recoil in the video.....

Well, you haven't really said what your budget is or what kind of setup you are looking for.

As for the basics, a complete RRA 9mm upper starts at ~$400 from adco.  A mag block will run about $125-180 and mags $20-30 each.  If you want a specialty upper, your cost will certainly run higher than $400.  IIRC, you can get a cmmg integrated lower for ~$300 complete, so your choice between that or a block for your existing lower.  It's almost always going to be cheaper to build an AR because of the FET...

If you have to have colt stuff, it will probably be cheaper to find a deal on a complete gun since used colt parts are not terribly plentiful and more often than not priced higher than new ones...

As for conversion kits being nightmares, that is a big YMMV depending on the individuals choice of parts and their capabilities to properly assemble and troubleshoot as necessary.

From reading on here, it looks like budget 9mm's are a headache. I set aside $1200 so I could get a new one if I had to, but I'll keep looking for a used one with a horsey on it in the meantime. Not in any big hurry. I've been getting rid of the stuff in my collection the I'm "meh" about and getting stuff I always wanted.

At todays price for Colts.... I don`t believe you can build a quality gun
at the level of a new factory Colt for any savings at all....Plus building
one negates any warranty....Now if you like to learn how to build a AR
then thats fine but saving money isn`t going to be a factor....Jim

This is what I've got now in my RRA 9mm:

RRA lower $300
RRA upper w/ramped bolt $500
Hahn top loader mag block $175
Spike's buffer $50
Colt long finger bolt catch $20

I like my setup and I was able to built it slowly but it's difficult to build a cheap 9mm AR. So a complete Colt for just over a grand is a pretty good deal.
