ROLLER +8 NEW, HK CONTRACT

+8 roller new.  HK contract production made on HK tooling in an HK licensed facility using correct spec. metric steel. 

These are way better, much harder and much more durable than any U.S. made rollers that have been produced. German and HK Contract rollers have a Rockwell hardness of 63-64. U.S. made rollers we have seen have hardness of only 44-48. 

ALL ROLLERS ARE PRICED PER ROLLER! So order two if you want a set.

Fit all HK Bolt Heads including HK91/G3, HK93/33/53, HK94, MP5, SP89 all clones and the Cetme.  Plus Size Rollers increase bolt gap.  Minus sized rollers decrease bolt gap.

For those choosing between U.S. made rollers or HK contract rollers: German HK rollers have a rockwell hardness of 60-64 (depending on era).   HK contract rollers also have a rockwell hardness of 60-64 as they are made from the same material.  All of the U.S. made rollers we have seen have a rockwell hardness in the 40s which is way too soft.  We stocked some of the U.S. made rollers when they were the only option available.   Today however there are better choices.  The quality of our German HK or HK Contract rollers cannot be matched.
