Frequently Asked Questions

How do you operate the safety on an HK-93?

The HK-93 safety selector is on the left side. The upper position is 'Safe' (S), and the lower position is 'Fire' (F). Ensure it's in the 'F' position before attempting to fire.

What is the 'HK slap' and why is it important for the HK-93?

The 'HK slap' is a technique where you firmly strike the charging handle forward after inserting a magazine. This ensures the bolt is fully closed and a round is chambered, a critical step for reliable operation of the HK-93.

Does the HK-93 have a last-round bolt hold open?

No, the HK-93 does not feature a last-round bolt hold open. After firing the last round, the bolt will slam shut, so you must manually cycle the action to chamber a new round from a fresh magazine.

How do you aim an HK-93?

Aim the HK-93 using its iron sights. Align the top of the front post with the top of the rear notch on the HK rotary drum sight for accurate targeting.
