  • Close-up of a buffer spring for the G3 rifle Close-up of a buffer spring for the G3 rifle

Quick Overview

Springs are perhaps one of the most underrated components of any semi-automatic firearm. Repeated compression and decompression will weaken a spring and eventually lead to breakage. Basically, the more rounds put through your firearm, the greater the chance a spring will break.

Like any spring, the G3 buffer spring is designed to store (when compressed) and release (during decompression) energy. In the case of the buffer spring, this energy is the direct result of an impact from the bolt. Designed to absorb and release the energy created by the action, the buffer spring is one of the most important springs in the G3.

For $3.95, you can be prepared with an original Heckler & Koch part if you ever happen to fire the fatal round that destroys your buffer spring.

Availability: In Stock



The G3 buffer spring is housed in the buffer assembly. 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 springs. If a part breaks or fails, a repair or replacement is necessary.

It is also important to consider availability. At this time, 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.

  1. A Must! review by Uncle Mike on 4/6/2017

    Buffer Spring was in good over-all condition. Definitely good for a spare. Price was outstanding and shipping was fast. Great product!

  2. Good for spare parts kit review by HK Al on 8/14/2016

    I bought these for a spare parts kit I'm building. It was great deal compared to other places. The buffer springs were worn, but serviceable.

  3. Good item to keep on hand review by RemMax on 5/22/2013

    Having finally managed to get one of my G3 buffer assemblies apart for routine maintenance I found the 50 year old spring was broken.
    So now once I get the other 4 apart I am glad these are available at a fair price.
    Needless to say, I'll most likely replace all of them and pick up a spare with it, but the point is it's nice to have a spare on hand as the 50 year old spring in your gun is most likely due to be replaced.
    Also these can cost far more in some of the rip off sites so here is a good place to pick up a item you will likely need.
    Thanks KS
