AR 15 stuck front takedown pin

Sometimes a little lube can be all the difference.

That's what she said....

Word choice was with intent

You can get feeler gauges and trim them down to slide in around the pin. Then using the mallet as the lower sits on the buffer tube extension tap the pin area while pushing the gauge in around the pin from right to left. Tapping it will momentarily release some spring pressure on the detent holding the take down pin. Get it in and slide the pin all the way out. Take a piece of sand paper to the detent and to the pin itself. Smoothing the exit side of where it rests. It will allow it to come out easier next time.

I use some grease when I'm putting a lower receiver together. The magazine release, bolt catch, and pivot pins since this is your one chance to put grease on them. Unless you disassemble your lower receiver at some point.

So this may help if I had said it first the pin sits flush and tight to the lower and will not budge from there. Pics to come of that!

Try giving it a little twist along with some lube, and maybe even a little heat!

Kroil oil the snout out of it wait 1/2 hr and try the punch and hammer on it again.

 

[Kruel J]

Spit on it.

So from what I'm able to see it looks like the detent is halfway in the hole not just part of the tip

Dude, you're making this too easy!

You didn't put the detent plunger in first then the spring did you?

No lol. I put spring then detent

 

[solv3nt]

No lol. I put spring then detent

You're still whacking on that thing?!?!?!?

I wonder if the " dent" the detent engages in the pin is oversized and it is acting like a locking pin and won't disengage. If It is too deep it will hold the pin and not let it disengage.

That's exactly what I belive it is. I'm almost 100% sure that's what it is.

Do you have a Dremel tool with the cutting wheels? Get some painters tape and put it around the pin to protect the lower receiver and cut it. Take your time since that is very nice looking lower.

That's the right pin.
The detent is stuck you probably need to use the hole that others have point out.
Use a needle or something to take pressure off the detent.
Then try a hammer and punch.
You might need two people .
One to hold the lower and the needle and the other to do the hammer work .
I would add some lube also just in case it's stuck.
Brass or plastic hammer and punch.

 

[EPS]

If your lower has the hole if not you need to get something small enough to get that detent pushed back .
OR JUST PUT IT IN A VICE AND GET A HAMMER AND PUNCH .
and hope for the best.

 

[EPS]

Hold on I have to go back and look at pictures

 

[EPS]

Ok you don't have the upper on there .just cut the pin and buy a new one
