Hey guys, I'm not sure this is in the correct forum, but on my AR the pin above the trigger slips out causing a jam and mis-fire. Do I have to get a new pin?

Thanks

Is your hammer spring in the correct orientation that the legs of springs are holding down in the grooves of the pin? See pics in link below.

I believe so.

Can you remove the upper, and take an image of your lower looking straight down onto your trigger pin? Especially showing how the two legs of the hammerspring are engaging onto your trigger pin.

See post #3 of the link I sent you earlier.

you might want to try anti-roll pins, $20-30 and they stay put

it looks like one it a tad inboard

Hard to see, but it does look like the leg in the lower part of the image is very askew. The leg needs to sit on the groove of your trigger pin, or the pin will slip out. Are you getting bad or light hammer strikes?

Take a look again at the link I sent you. In an analogy, think of a roll of toilet paper. If the hammerspring is coming over the top of the roll of a toilet paper - its's good. If the hammerspring is coming under the roll of a toilet paper - you aren't going to get the right tension, and it might allow for your leg to run askew.

Try re-posting your pic in the centerfire forum, to get some more opinions to take a look at the image.
