AK reload: Why BUMP the magazine?

This video explains the necessity of 'bumping' the magazine during an AK reload, specifically when using Yugoslavian bolt-hold-open magazines. The follower in these magazines catches the bolt on the last round, creating pressure that can prevent the empty magazine from dropping freely. Bumping provides the extra force needed to overcome this friction. Standard AK magazines lack this bolt-hold-open feature, making the bump unnecessary.

Quick Summary

Bumping the magazine during an AK reload is crucial for Yugoslavian bolt-hold-open (BHO) magazines. These feature a follower that catches the bolt on the last round, creating pressure that can hinder the empty magazine's release. Bumping provides the force needed to overcome this friction for a smooth reload.

Frequently Asked Questions

Why do some shooters 'bump' the magazine when reloading an AK-47?

Bumping is primarily necessary for Yugoslavian (Yugo) bolt-hold-open (BHO) magazines. The follower in these mags catches the bolt on the last round, creating pressure that can impede the empty magazine's release. Bumping provides the force to overcome this friction.

What is a Yugo bolt hold open magazine?

A Yugo bolt hold open magazine is a type of AK magazine, specifically from Yugoslavian production, featuring a follower designed to catch the bolt carrier group when the last round is fired, signaling an empty weapon.

Is bumping necessary for all AK magazines?

No, bumping is generally only necessary for Yugoslavian bolt-hold-open (BHO) magazines. Standard AK magazines do not hold the bolt open, so there's no pressure on the follower preventing the magazine from dropping freely.

How does bumping help with AK magazine reloads?

When using Yugo BHO magazines, the bolt rests on the follower, creating friction. Bumping the fresh magazine into the rifle provides the necessary force to dislodge the empty magazine and seat the new one efficiently.
