UMP and USC  HDPS Barrels



Those are the HDPS CORP production UMP and USC Barrels made with the cutting edge CNC machinery that will be available for sale in a few weeks. I got some samples for test fire and they work 100%.

You can find reproduction barrels for the UMP and USC in two places only, BUT you will find the exact specs of the originals German made only here. Just compare the UMP barrel. Our barrel is an exact reproduction with all German specs. not a  low profile barrel.

Also, our USC barrels have the same design of the UMP barrel by the chamber face allowing :

1- The use of a 16" barrel in the UMP, so PD's and Govt. Agencies that always wanted a little more speed and accuracy on their  UMP's, now have a choice for a quick barrel swap.

2- Will accommodate the enhanced USC bolt for those that want to be able to load your converted Carbine in silent mode.

Important - Third Version of Barrel "USMP"

This is the special USC 16" barrels made WITH the UMP quick attachment tip on them, so you guys will be able to attach the UMP flash suppressor or a sound suppressor.

Barrels are dark Gray in color like the Original German barrels (if you want in black, just ask )

UMP HDPS barrel test fire at 25 yards, fired 7 rounds only so would not destroy the target  and you can see the hits...and I did not really put much effort, stand up position, no sling.


Buyer be aware...B&T products for the UMP (flash suppressor and folding stocks) are not uniform in specifications, parts vary greatly....some flash suppressors work just fine and some others require some work  and fitting.

 I have tested 5 of those suppressors in an OEM German UMP barrel, 3 fail to slide in and lock without requiring fitting.

We have plans to offer our HDPS Phanton Flash Suppressor soon! It will cost way less.
