I have a V Seven 2055 Carbine Buffer Tube and a Magpul ACS-L Mil-Spec stock. The stock does not stop at the end of the buffer tube, it pulls right off. Both are milspec so that shouldn’t be the reason. Any ideas?

Would you post a picture of the underside of the bare buffer tube, please? Might go a long way towards getting you an accurate answer.

Many of the new buffer tubes (Vltor A5) are longer than a carbine stock tube. They stock doesn't cover the entire tube. And they make a 5 position and 7 position tubes, the 7 isn't covered by the stock completely.

The longer tube is supposed to match the middle ground between carbine and rifle making the gun run smoother and more reliable than a carbine gun.

At least that is part of the equation for the A5 systems. Yours may well be the same.

Let's see a pic with stock on and collapsed all the way and see if its what I am talking about.

I’ve never seen a milspec receiver extension that looks like that. Have you tried the stock on an actual “milspec” RE?

I think he is referring to mil spec vs commercial tubes.
I could be wrong.

I don’t know what a link to the product does for the discussion. They can claim whatever they want, but those odd cutouts make me question their claims. Here’s what a milspec RE looks like.

The one pictured and linked to clearly had some unnecessary aftermarket voodoo.

Could be or it could be an instance of manufactures making claims about “milspec”.

I think they're referring to the diameter of the tube being "milspec" for the purpose of fitting the correct stock. Not that I see that many "commercial" spec stocks or buffer tubes these days compared to the 90s and 2000s.

Good riddance to that American Mediocrity Fad. The OP has a weird aftermarket RE that his stock slides off instead of stopping at the longest spot when the latch is squeezed. No idea why without getting the parts directly in front of me.

The buffer tube appears fine. I would make sure there’s nothing wrong with the stock. There should be some kind of detent or pin that protrudes into the tube of the stock. Is the spring weak? Can you try it on a different buffer tube?

Could be the stock, but..

The thing is... the stock is Magpul, and the RE is some oddball brand will unusual cuts. My money is on the circus part. Shoot.. the RE isn't even round.. it has flats on the outer diameter.

I blame Magpul for it being around as long as it has been.

True. They did cater to that crap a bit.

What does this $105 RE do that a $40 BCM ones doesn’t?

It also in theory has more drip.

No cap. Lol

OP, what is the dimension of the top of the buffer tube to the bottom of the very back?

Let's get a picture of the inside of the Magpul

Transfer money from the wallets of the unwise to V-whoever's account.

A completely mil spec (not just diameter) RE is plenty strong. This is another "solution" to a problem that doesn't exist.

Op can start his own box of shame, throw the Magpul stock in there with it and be off to a good start.
