Product Details
+4 roller new. HK contract production made on HK tooling in an HK licensed facility using correct spec. metric steel.
We only recomend rollers made by HK, HK contract manufacturers or RCM. Other US made attempts are just too soft. German, HK Contract and RCM rollers have a Rockwell hardness of 63-64. The other 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.
