This guide details an efficient reloading technique for MP5-pattern firearms, as demonstrated by Polenar Tactical. It advises against the popular 'HK slap' due to potential receiver wear and interference with modern optics. Instead, it promotes a faster, more practical method using the bolt release lever or pushing the charging handle forward with the thumb, which keeps the hand in a ready-to-fire position. The video emphasizes empirical data from a shot timer to prove the efficiency of this technique.

Quick Summary

Avoid the 'HK slap' reload on MP5-style firearms due to potential receiver wear and interference with optics. A faster, more efficient technique involves using your thumb to press the bolt release or push the charging handle forward, saving time and keeping your hand in a ready-to-fire position.

Frequently Asked Questions

Why should I avoid the 'HK slap' when reloading an MP5?

The 'HK slap' can cause mechanical wear on the receiver over time and may interfere with modern optics like EOTech sights. It's also less efficient, taking longer than alternative methods.

What is a faster reloading method for the MP5 than the 'HK slap'?

A more efficient method involves using your thumb to press the bolt release lever down or push the charging handle forward. This keeps your hand ready to shoot and is demonstrably faster, saving time.

Does the MP5 have a last-round bolt hold open?

No, the MP5 does not have a last-round bolt hold-open feature. This means you must manually lock the bolt to the rear after firing the last round before reloading.

How much faster is the thumb-release reload compared to the 'HK slap' on an MP5?

Empirical testing using a shot timer shows the thumb-release method takes approximately 3.58 seconds, while the 'HK slap' takes about 4.22 seconds, making the thumb-release method about 0.64 seconds faster.
