I was shooting my AR the other day and I could swear I was getting some trigger slap. Is this possible with an AR? What is the fix?

Checked the FAQ, but I missed anything on this problem.

Thanks.

You nailed it again Tweak.

I did one of those 15 minute trigger jobs on my hammer spring a while back and although I like the trigger pull and it never light strikes I think the weakened spring is allowing the hammer to swing too fast and far.

Now, to replace the spring with my spare or cut a little off the hammer spur. Decisions, decisions...

Thanks

It's usually caused (if the FCG was good previously) by correcting improper timing by cutting the nose of the disco.




I had installed new FCG parts (hammer, trigger disco, springs and pins) a little while back as I was experiencing doubling problems. I didn't notice any slap, but the hammer spring was a lot more stiff than the old one and so the trigger required more pressure before release. I cut one spring leg to 3/4 inch, but did not bend the other so I ended up with a lighter trigger and still had pretty good lock time. This past weekend I put about 300 rounds down range and the slap was just enough to make me wonder if that's what I was really feeling.

My theory was that the hammer was actually bouncing off the bottom of the carrier and hitting the disco due to the weakened spring.

Or not.
