You need to start with a usc and figure about 1500.00 for the conversion.

Thanks. For those of you that have the conversion is it worth it? Any calibers other than .45 possible? What about converting a HK94. About the same cost?
No idea about the HK94.... as for the USC/UMP:
You can do multiple caliber conversions for it, .45 .40S&W and 9mm, although the 9mm bolts are nearly impossible to get. The bolt and barrel are pretty expensive though. HKparts.net lists the .40 cal bolts for just under 600 bucks, and the barrels (225 for a 16" one and 175 for an 8" one, which are US made barrels, or just under 500 for a used german UMP-40 barrel). with 9mm the bolts are VERY hard to find....
The conversion, ergonomically alone is worth it IMHO, but Its hard to get a more kickass pistol cal. carbine. You will want to start off with an HK USC45... Then you'll need a UMP lower (I'd go with the Semi-only lower, although I think you can use any lower since you'll put the semi-auto internals into it), the stock block, and the folding stock. Plus magazines. If you register your gun as an SBR then you can get the 8" barrel too.
Now if you get the 8" barrel and SBR it on a form 1 or whatever, then you dont need to worry about "compliance" parts. If you want to keep it NON-NFA, then you will need some US made parts. HDPS makes a trigger, and magazine follower and floorplates I think, but you'll need them for EVERY magazine, which can get pretty pricey. You can go with an 16" US made barrel which would also count as a part.
HDPS is one of the big players in the USC/UMP conversion world. Check out their website
HERE and scroll through. They list the whole kitten caboodle with all the parts you need (UMP lower - either semi-semi or semi-only-burst, stock block, folding stock, trigger parts (including , magazine and US made follower and floorplate) for $1375 for the FBI trigger group (semi-only) and 1395 for the "burst lower"
NOTE: the burst lower has the semi-auto parts installed, so it only 'looks' like the auto trigger group. The sear area has been filled and machined so you cant install the auto sear into it.
All you need is to add a USC and do some minor work to it (all explained at HDPS).
You can also try and look around for some already completed ones, IIRC there were some going for pretty good prices.
