Description
HK US MP540 Undersized Locking Roller, -4
The proper roller size is essential for proper headspacing of bolt gap.
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.
