Strange AR Hammer
I was working on a rifle that had problems. It would fire and pick up and chamber a new round, but most of the time the hammer would follow the carrier and not fire. I broke down the lower and when I pulled the hammer and compared it with a known good one, I notice that the shape was about right, but the length of the hammer was shorter. The Hammer had a notch, but the length of the notch was 1/3 the normal size and measuring the hammer, the length was shorter by almost an 1/8 inch.
There are 2 S's marked on the hammer head at a 90 degree angle from the length and the hammer is not been ground down ( Was made this way )...does anyone know what this thing is? Sorry don't have a picture at this time
Will try to get photos tomorrow
All brand hammers are not the same length. Nothing really unusual about the length difference.
The hammers with the two S marks have been in a lot of different kits lately but they are not the only ones that are made to the shorter length.
this one sure has a hard time recocking, got lucky once and had a about a 6 shot string, but usually it was a FTF after firing...like I said, would reload a new round, but fail to cock the hammer
The hammer might be a problem if the trigger notch on it is off. I was just commenting about the length..
