dumb question

[brybenn]

Why is there a small spring in some ar pistol grips?
I took off the stock grip on my jrc and there is a spring recessed in the top of the grip pressing against the chassis. The replacement ergo grip I just bought for my mdt chassis has the same hole placement

Look at the safety selector.
On the safety selector is a tiny channel groove.
Now look in line with the safety selector down to where the bottom of the reciever lines up with the top of the pistol grip.
Notice how when you change the safety selector it 'clicks' and holds in place.

That is a tiny pointed dowel that rubs against the groove in the safety selector and holds place in the channel.
It is called a 'detent'. It is puished up against the selector by that tiny spring which comes out when you take off the pistol grip.

When you put the pistol grip back on, make sure the detent is in the hole, pointy ebd towards safety selector and then place the srping in behind it.
The spring will stick out jusst a bit, when you put the grip on it will compress it back in place.


There is another tiny detent and spring holding the front take down pin in in a similar style.

Make sense?

Yup. I feel dumb now. Thanks. Still new at the ar stuff. Just checked and my jrc is still working good so I must have got it put back the right way

1. The only dumb question is the one you are thinking but won't ask.
2. Don't feel dumb about your question. You simply didn't know but someone helped you out. All good.
3. Despite 1 and 2 there are many folks here that will pounce on questions or comments with a negative attitude to make themselves feel smart, important, or simply takes pleasure in making others feel miserable. Ask all the questions you want and ignore those aligning with point 3.

Amen, Moe. You hit that thumb right on the nail.

Speaking of those small springs, if you ever go about changing the buffer tube, namely the plate, on your AR, there's a spring held in by the plate that'll fire across the room if you're not careful about it.

It's for the rear takedown pin, before you ask

 

[brybenn]

Good to know thanks. I'm not into ar platforms. I love my just right carbine but thats about as close as ill get I think. That said I'm really starting to like chassis rifle style which has led me to start swapping parts around
Lawn gnomes answer was perfect. That's why I love this site

Moe for the win

85 pushes 86 up to give you that solid click when rotating 104

There are two other little springs 110, 97 that keep the take down pins in place so you can't pull them out when you pull on them that work the same way.

Good on you for asking the question, most of us learned the hard way by taking stuff apart, losing springs etc.

 

[brybenn]

Oh I lost the spring. It hit the floor and my 160 lb mastiff decided to help me by stepping on it and getting it stuck between her toes. I found it eventually after several minutes of what one may call a mantrum lol

 

[lawn gnome]

You are not the only one to launch tiny springs and detents across the floor into oblivion.
Check out the diagram and ring up a gunshop/sponsor telling them what spring or detent you want.
They won't laugh too hard, you aren't the first.

If you work on a lower like this in future or any tiny bits,,,lay down a small hand towel where tiny bits tend not to roll away.

My NEA has not one but two springs

 

[Kidd X]

My NEA has not one but two springs

Two springs in the grip??

 

[lavino]

Two springs in the grip??

yeah.. some weird design they have. One for safety and one for takedown pin.. somehow these NEA ones don't go through the castle nut like other ARs I have seen.
