Question about A2 butt stocks

[MAGG]

I believe that is what the old school solid ones are called ( like the ones that were on M-16's)

Will those fit on any type of AR? I have a colt and also a wyndham AR and would like to throw this type of stock on them. I have never done it tho and was wondering if they are all compatable? thanks

Are you installing the buffer tube as well?

 

[mac1911]

Yes the extension tube/buffer tube threads into rear of receiver. Then the stock slips over the tube attached by the upper rear screw.

 

[ErnstStavro]

Yes, you may need to change the buffer tube, spring and buffer as well...depending what is already installed.

What are you removing? Why the change?

 

[SJan]

yes, it will go on any AR, you will need a rifle length receiver extension (buffer tube) its best to get a kit from a reputable manufacturer

I have never assembled or changed anything out on an AR so I won't lie and say yes...I would prob have a friend help me/teach me.. I just didn't know if you needed a certain brand for a certain gun

I just like the look of these and never really dug what is on there now...just a cosmetic thing

 

[shanef]

make sure you have a proper stock wrench if existing stock is faux or pinned col. stock....

+1 for the Rock River Arms butt stock kit. Put one on my match lower & very happy with it. Easy to do on your own, or a very quick and easy job if someone is going to help you.

i just watched the videos that shanef and mac1911 posted and def think i can tackle this on my own...thanks for the feed back everyone.

the only potential tricky part could be removing the old castle nut. good luck.

You may find A1 stock which is 1 inch(?) shorter more comfortable. It installs identically to A2.

+1, I have the RRA A2 butt stock kit on my match lower.

To the OP, when you remove your existing stock, mind the spring that applies pressure to the rear takedown detent. It's pretty easy to loose or even not notice.

What does that spring actually do?

 

[SJan]

What does that spring actually do?

it holds in the rear takedown pin

This is why everyone should have the opportunity to build a lower (install a lower pack kit into a stripped receiver). Answers all the questions and takes the fear out of changing things out to improve it to suit you.

 

[mac1911]

What does that spring actually do?

The spring puts pressure on the detent for rear take down pin.
About 1:15 on the video I posted.
If you have a M4 extension tube with a castlenut the castlenut holds a plate on the back of the receiver.

Thanks guys-
I swapped out my butt stock recently and found my spring laying on my bench after.
I then had a WTF?!? moment....
