  • G3 Hammer - Original Part Made in Germany by HK for the G3 G3 Hammer - Original Part Made in Germany by HK for the G3

Quick Overview

In any hammer-fired rifle, as opposed to striker-fired, the hammer is one of the most vital components. Aptly named due to its similarity in both looks and functionality to the common tool, the hammer is responsible for striking the firing pin, which in turn strikes the cartridge primer. Most semi-automatic rifles are hammer-fired. Such is the case with the Heckler & Koch G3. now offers replacement G3 hammers. Like many of our G3 parts and accessories, the G3 hammer is an original HK part. The hammer is housed in the trigger pack and held under spring tension around the hammer pivot pin. When an appropriate amount of pressure has been applied to the trigger, it will act on the sear, which in turn releases the hammer and allows it to continue the firing sequence.

The hammer is one part of a firearm that takes quite a beating. Ensure that your rifle is never out of order due to a worn out hammer with a replacement G3 hammer for $7.95. As our mothers always say, “It’s better to be safe than sorry.”

  1. Not a part that wears out much but.... review by Rich on 2/11/2013

    A friend of mine brought his HK 91 over and said he was having problems with his rifle not firing everytime. He knows nothing about these complex works of art so I pulled it apart and as soon as the trigger pack came off I saw a hammer that looked like it had been firing full auto for 50 yrs! It really was wore out like a old camshaft lobe, the top of the arch was wore flat. Suspiciously, the other parts in the pack were fine and there was strange absence of metal shavings. I asked him if he had taken the rifle anywhere for some reason and he said he had taken it to a local gunsmith to make sure it was all in good working order (a checkup) so to say. We figured out pretty fast someone had swapped his hammer with that of a well used and I mean used hard G3. Well, I had the extra hammer I had gotten from here and installed it. From start to finish 2o mins later he had a 91 that was functioning perfectly. The replacement had some finish scuffing but no material wear. We then went to the so called gun smith, tossed the wore out hammer up on the counter and said "Pay your 8 bucks for a surplus hammer like anyone else honest would. He cussed and kicked us out but he knew what he did. He did ask why it was in 2 pieces and I said I cut it on the bandsaw so you wouldn't screw anyone else with it. So, the 8 dollar hammer from KS saved the day.

  2. If it's used you can't tell review by Brian on 1/17/2013

    The hammer I received the other day looks brand new. I'm doing a trigger job on my H&K 91 so I wanted a spare just in case. The cheapest price on line also. Thanks Keepshooting.

  3. Excellent price review by Nato on 9/4/2012

    This is a G3 part, to stay in BATF compliance the sear notch on the hammer should be ground flat when used in a semi-auto weapon.
