Is it really worth it to convert my USC into a 9mm UMP? Or would I have just as much fun making the USC a SBR and throwing a suppressor on it? Also. What should I expect to save money wise to creat this 9mm UMP? This would be my first time doing anything like this. - Thanks.
I am debating the same thing. I estimate $2k, all to get a folding stock and SBR threaded barrel, which also would require at least 6 months. This for what cost initially $850, and that wouldn't be semi auto either. Pretty anti-climactic. It does shoot well, otherwise I'd have serious buyers remorse. I am contemplating taking Dremel to a spare USC stock, grinding off the thumb hole portion. That would be a hell of an improvement. But $3k+ for a 45 that folds? I gotta re-evaluate.
The most ingenious conversion I've seen are the German folding stocks and double stack mags that fit the USC without modification, but I here the quality isn't good. Too bad.
This is a real dilemma at todays prices. Only 2 years ago I was able to make 2 of these for around $2100-2200 apiece but that was finding good prices at various vendors and it took awhile. None of them have any parts in stock any longer. The guns were $1200, mags $45 and lowers $260. I suppose you could say I have 3 because one is now a 9mm so that was an additional $900. I was fretting about those prices then...
I'm going to speak on the contrary. I just finished mine(minus sbr'ing) and I absolutely love it. All y'all saying not to do it are nuts. Have you shot a USC without that stupid thumb hole stock? This is the way they were meant to be shot.
My form 1 (SBR) is already downrange and I plan to cut and thread it for a suppressor. I'm even thinking of having the "tip" of the 16" barrel (with HK 45 markings) made into a thread protecter. It will be a fun little carbine to shoot. I have contemplated using a dremel on a spare stock to "clean up" the thumb hole portion but thought I saw somewhere (on this board) that it was taboo without all the US and UMP conversion parts. The sbr/suppressor combo will be fine by me.
Ubetit that suppressor looks frickin awesome on the UMP!
OP: for less than what you would pay for an MP5 you can have a weapon which is capable of being changed to 3 different very popular calibers.
I cannot think of a single other firearm which you can change calibers on as easily as the UMP. Or even one which can change to 3 different calibers
in the first place. Really, they are about the same price range as a SCAR or ACR (if you do some of the work yourself!)
I have all three calibers for mine and it's sbr'd. It's worth it. Just take your time buying all the parts. If you're patient you can pick up some good deals on the parts for time to time.
You could do a 16in 9mm conversion and have tbostic open the USC mag well. Just an idea.
