HK UMP - USC RAILS

Mil. Specs Picatinny Rails

See the differences, double click for bigger image

ATTENTION, MAKE SURE THAT YOUR ACCESSORY WAS MADE FOR MIL-STD-1913 PICATTINY ARSENAL RAILS

No other outfit have this quality at low price, they are our FOURTH generation and IMPROVED with NO sharp edges, upper rail is just a little over 1" longer but give you almost 2" for  more choices to fit your scope or sight, rounded front face for snag free and 100% base contact with receiver giving you  a complete rail stability. Lower rails no longer have the notches for KAC covers, they were just another sharp points and we have now a variety of snap on much cheaper rubber covers for those rails that don't use those notches anymore.

 

And don't forget, those are not just anodized, they are Teflon Molly Coated for more durability, no milling marks and a texture close to the polymer texture.

Advantages of HDPS CORP. Barrels

Those are the HDPS CORP production UMP and USC Barrels made with the cutting edge CNC machinery by Green Mountain Rifle Barrels Co., a company  in the specialty business of only make quality barrels for 31 years...

Those barrels are made from blanks of 4140 Chrome Molly Steel (Stainless Steel for the UMP Barrels), turned on centers, machine finish. Stress relieved & Air gaged to +/- .0002".

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- All barrels are compatible with USC bolt/carrier AND UMP bolt/carrier!!

Important - Third Version of Barrel "USMP" is a 16" with  the UMP flange.

 

USC  HDPS 16" Barrel  $200 (IN STOCK)

 

 HDPS UMP barrel 7.87" in Stainless Steel- $215 (IN STOCK)  Your Choice, in Gray or Black!!! you can choose colors only here!!

 

USMP HDPS 16" with UMP flange $210 (IN STOCK)

 

The new HDPS UMP Stainless Steel barrels are the best solution for your registered SBR as you may plan to attach a Sound Suppressor or a Flash Suppressor and you can trust that it will stay tight there, other solutions can only become a serious problem, example.... cutting an USC 16" barrel that has a twist rate for it's length and solder a tip to it is a recipe for a catastrophic failure.

Special Notes:

Be aware of after market brands offering a "magical" special refinish on those barrels, is no such thing, those barrels must be between +/- 0,001"~0,002"  and in order to apply such special finishes their barrels in order to work must be under the specifications to make up for the thickness of their finish, once finish wear out you also have an out of specs barrel flange.

Also, about 9mm and .40 S&W barrels, we are not offering them because would be the same of selling a car without an engine as the UMP 9mm bolts are not  available for sale and very difficult (and expensive) to find.

If you want a HK UMP conversion done in 9mm or .40 S&W, make sure to ONLY USE HK parts, several people that purchased after market brand of UMP and USC 9mm barrels ended up with an expensive paper weight due to specifications and not being able to find a 9mm bolt.

 

 

 


 FYI-  Upcoming Projects for the USC

1- Upper receiver to accept all USC/UMP internals (for those that asked me over and over...it's coming, now you will be able to have that  UM-Pistol)

2- Tab to lock folding stock to upper receiver

3- Fake UMP look a like sound suppressor

4- Real Sound Suppressors line
