AR castle nut spring needed

[tarheelbball]

Put a qd end plate and lost that spring. Not the one with the pin for the buffer tube. Locally in Chattanooga can these be found or do need to go online? If I go online what other pins, springs should I get since I'm going to pay shipping. thanks

When you look, it's called the take down pin detent spring. Same one is used for the front pivot pin.

 

And the little detent itself stayed in there, right? If not, you'll need it also.

I'm new to AR's. But where the take down pin is for the rear there is a pin in there because I had to slide it back so I could keep up with it. I think that's it, I guess I need to go find some new vocabulary word also. Thanks

I tried twice on an iPad and twice from my phone Dolomite to send a message. I'm not showing the message in my message box. I'll check again later.

Give me your address.

Also, here is a tip to prevent it from happening again. Take a 4-40 tap and tap the rear detent hole. Only go deep enough for the shortest 4-40 screw you can find. Grind the spring to remove the small amount as the set screw is long. Then install like normal and use the 4-40 set screw to capture the spring and detent. I do it to every AR I build to save the aggravation.

This is a great idea! Thank you for the tip.

You can also use one of these pins and just forget the whole assembly. Drawback is you can lose them.
