A2 stock with carbine buffer/spring?

[CK_32]

Been googling and have a question for A2 stock users.


I have a Carbine stock with buffer/spring set for my 308. Another member gave me his A2 stock, screw and cap. My buddy and every google search has told me I need and have to go out and buy a A2 spring and buffer that's different from my carbine one. Because of length.. Ok I get that.


But my question is, a weight is a weight, a spring is a spring as long as they are both rated for 308... Shouldnt I be able to get the A2 buffer tube, put a block in it and replicate and make it like the carbine stock with no issues?


Besides the length which again the block should fix, what is the difference? That should work fine no?

I just feel its kinda useless to drop another $35 on a spring and buffer when I have a set already just smaller length again which a block should solve. Unless I'm missing something

Personally I would opt to spend the extra $35. Why because typically depending on the spring construction a longer action spring will give you a more reliable weapon. Because the spring rate deviation will be lower making the carrier cycle more consistently.

Yes that shouldn't be a problem. Its just like adding a spacer.
But since all you have is just the stock, why not get the whole kit meant for it?
I used to have an entry level RRA stock with carbine buffer, tube/spring. The stock was too short for my liking so I replaced it with an A1 (3/4" smaller than A2) and just added a spacer and a longer screw.
In your case, you can probably fashion out a round tube that'll fit inside the buffer tube. Just make sure its cut to size.

I see no benefit to "MacGyver" the rifle for lack of $35 in parts. A2 stock still feels right to me weather it's a 556 or 308 AR type.
If this is the rifle that is in process of completion you posted in another thread then pony up and do it right. It should be a good hole puncher.

The reason I'm trying to not go and buy another A2 spring/buffer is because I'm already going to use up $30 for a buffer tube so this can work... Which is just going to be soon replaced by a UBR which will be using the carbine spring and buffer which is just a waste IMO that I wouldn't mind putting towards other parts and reloading components if this can be solved by making a simple cheap block and be fine.


I see RRA has a blocker for 9mm to do just what I'm looking to do here but I need to figure out how long to make my blocker or if someone has a block out there pre made.


And yea I know we all should and want to do things the expensive and right way but that doesn't mean it's the ONLY away. Not so much a MacGuiver more than a cheap simple fix to a cheap simple solution if my thinking is correct. Cause again I don't see how anything should change if I block out the A2 tube and make it the same length as my carbine and be able to use the carbine spring and buffer again being it's now the same thing. Just a shorter tube than a longer one with a special longer spring needed.

If its only temporary, why spend for the RRA spacer? Just get a rounded piece of wood cut to size and be done with it.

Pretty much what I had in mind. I just wanted to see if a company had one so I could get specs and measurements from it and go off that. But all I found was the 9mm which I don't think would work.

Another thought.
When you test the rifle for the first time you may run into issues that are going to be more difficult to trouble shoot. Over or under gassed or buffer/spring/receiver extension issues. You really need to test with a known config that has a track record of reliability. Having said that... report back with your findings after you test it with spacer and carbine parts installed. Party on dude!

Good idea^

I'll run a few mags with the carbine stock and see how it does. Then if all goes well then do the little conversion. And see how it goes from there. Lad you mentioned that actually.

My main fear is over travel and making BCG contact with my receiver and blowing the back out.
