Lately when fire my gun on semi, sometimes my rifle will fire two shots.  It cycles those two shots fine, but any ideas what is causing it?  Some run away silicone maybe got on something?

I never used spray silicone and I've been cleaning my Lm4 regularly too.

Worn out trigger sear? Are you pulling the trigger all the way? This is kind of hard to diagnose without knowing exactly what you're doing

Hmm, I had to look up what a trigger sear was, but I don't it is that.  Trying to look down the lower receiver I don't see any wear and my gun hasn't ever failed to cock the hammer.   I think possibly not pulling the trigger back all the way could be the problem.  It's mostly happened when I am firing to see if I need to adjust my hop up so I am not focused on pulling the trigger.  

Can under pulling the trigger cause that?  I've never messed with the trigger before so this is really interesting to learn.

Does it ever skip a shot like a misfire?

Not that I have ever noticed.  I have even been cycling my lm4 trying to get it to cycle twice again, but it hasn't yet.  I wonder if it was just a couple flukes?  It's by no means consistent, but I thought it was worth mentioning.

Keep an eye on it and let us know if it starts to happen again.
