G3 Locking Roller Holder (3-pack)

In my write-up for the G3 bolt locking piece, I expressed my impression with the design of the G3 bolt carrier group and my desire to hold a long discussion on the topic. Well, the long discussion will have to be put on hold again, as today we focus solely on a single component of the bolt carrier group. Today, we focus on the G3 locking roller holder.


As you may already be aware, the Heckler & Koch G3 features a roller-delayed blowback action that necessitates the inclusion of a pair of bolt locking rollers. As the bolt carrier moves into battery, the bolt locking piece forces these rollers outward into two small recesses and locks the bolt in place. Upon firing, the expansion of gases that results from the ignition of a propellant charge sends the bolt head to the rear, forcing the locking rollers inward and allowing the bolt carrier to move out of battery.


The G3 locking roller holder is a small retainer plate housed in the bolt head of the G3 rifle. The locking roller holder is designed to do exactly what you would expect a part called the locking roller holder to do – it holds the bolt locking rollers in place and allows them to move in and out of the small recesses. The locking roller holder is secured inside the bolt head by a small roll pin known officially as the clamping sleeve. Like many of our G3 parts, this is an original part manufactured by HK.


The G3 locking roller holder is one part of the G3 that experiences wear and breakage. That said it is a good idea to keep a few on hand. Our fair price of $2.95 will get you three locking roller holders and let you do just that.

The G3 locking roller holder is located inside the bolt head on the G3 rifle and sold as a 3-pack. This small retainer plate serves to hold the G3 bolt locking rollers in place, which lock the bolt into or release the bolt out of battery. It is an original factory part made in Germany by HK.

Spare parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly, including the bolt carrier group. If a part breaks or fails, a repair or replacement is necessary.

It is also important to consider availability. At this time, Keepshooting.com has a wealth of authentic, original factory parts from HK for the G3/HK91/PTR91. Not only are they readily available, but also they are cheap. Now is the time to take advantage.

I could not believe how nice these were, and to get three (3) of them at this price! The three I received were in no way surplus. Roll pins would be nice hint, hint. Thanks Keepshooting Review by Brian (Posted on 1/17/2013)

These appear to be original HK parts from the 50's, new unused excellent condition. The pin hole in the center is smaller than the contractor copies being sold, so you will need to insert the locking piece when mounting rollers so that the hole is properly aligned. No slop with these! Review by Nato (Posted on 9/4/2012)
