This is my first compact HK MP5, SP5, MP5K, SP5K picatinny rail. Made this for users who were having troubles with their normal long rails, obstructing their slaps (for the sp5k bois). So this should be no problems for you, fits perfectly for the Holosun 510c and other picatinny style optic mounts.
*EVERY COMPACT OPTIC MOUNT WILL NOT OBSTRUCT YOUR SLAPS*
