Help! Safety Selector Problem

[montana]

I had some early production "SGW" Olympic Arms lower receivers that were not machined to spec back in the early 1980's that caused selector lever issues. I still think your selector lever could be the culprit in your case. What manufacturer made your lower?

It's a PF lower and parts kit... I might be able to borrow a selector from a buddy at work and try swapping it to see what happens

[montana]

Your selector lever set groove seems to be machined a bit too short, which is a hair short of allowing your trigger to clear the selector. When you push the selector lever far enough to clear the trigger your pushing the detent past the machined groove in the selector lever which would be difficult to do. I would try and find another selector lever or send the one you have back for a replacement. If your new selector lever has the same results as your original one then your lower receiver selector detent pin and spring tunnel is probably machined out of spec and I would try and have the place you purchased it from replace the lower. Good Luck!

Any chance you put the safety detent pin in backwards? The flat side goes against the spring and the pointy end goes in first towards the safety selector.

Nope, had it in pointy end first

That's what I'm thinking as well... I'll see if I can scrounge up a different one to try

So I might just be overthinking everything now, but does it look like the hole for the detent is a little off center to anyone else?

I've got a safety from a PF LPK that I didn't use, if you want to try it let me know. Oshkosh.

The selector doesn't point straight up, but a little forward even when on fire. The trigger will fire if I force the selector to point straight up. Could the detents be slightly off from where there should be? Has anyone had this problem before? Am I missing something super obvious?

That's your problem. Was this an 80% lower? You can fix it by relieving the selector detent track on the shaft of the selector so that it will point straight up. The mechanical problem you are having is that the flat surface of the selector shaft isn't oriented perfectly flat when on fire, so the trigger trough tail is not able to raise enough to allow the trigger nose to clear the hammer notch.

Nope, this was a stripped lower and matched upper from PF

Let Mark know. He'll take care of you.

I appreciate the offer... After looking at my selector the detent and the indicator seem to line up fine, so I'm thinking something else is the issue... I'll keep it in mind if I end up needing one... thanks.

I'd try a different selector as suggested. The groove or detent stop might not be in spec. Is the flat section flat? Check for casting marks there and in the groove and detent stop.

The other remote possibility is the Geissele trigger tail is too tall and is causing the interference. Read the last reply from the OP.

I took a file to the safety selector flat and removed less than a thousandth of material and now it works fine. I'm guessing something was just a fuzz off.. It could very well have been the trigger tail. Thanks for standing behind your product Mark, can't wait to get it out this weekend and see how it shoots!
