Heckler and Koch -4 7.96mm Undersized Roller for Bolt Heads
The proper roller size is essential for proper head spacing and bolt gap. New HK German not surplus or used goods. German-made -4 roller, each roller is priced per roller.
Compatible with:
MP5, MP5K
HK91, G3
HK33, HK53, HK93
Please Note: The price listed is per roller. Order 2 (pair) for a complete set for the bolt head.
An easy way to remember the size you need to order - plus-size rollers increase the bolt gap and minus-sized rollers decrease the bolt gap.
