What's the big difference here between the two?

I believe (and I'm going from memory here) that the A2 is about 5/8" longer. Also, the plastic used in the A2 is supposed to be stronger somehow.

 

Both use the rifle length buffer tube. W/ the A2, there is a little piece of plastic that plugs up the difference in length and goes between the end of the buffer tube and the inside buttstock end of the stock. On the A1, the buffer tube goes flush to the inside of the buttstock.

So is a Sully Stock an A1 Stock?

I believe the Sully uses a Carbine buffer tube vs. the rifle length buffer tube. The Sully is shorter than an A1, I don't know by how much though. I understand the Sully stock is roughly the length of an M4 stock pulled out to the first notch position, not flush up against the receiver. I think that when you order the Sully, they give you a buffer tube in the package.

 

I'm going to go w/ a Sully stock for my Bushy when funds allow.

Strength was the biggest change. The old stocks were somewhat flimsy and breaking during rough use.

 

Then there is the Entry Stock that is for use with tactical body armor.

A couple people on the forum run the Sully stock, I believe Caine being the only one that I remember off the top of my head. I have a Sully stock in the mail, and I was hoping to get it sometime in the next few business days or so. I do know that they do come with their own set of everything... http://prostores2.carrierzone.com/servl ... Categories

Is the Sully stock shorter than the ACE Entry stock?

I've been trying to find a picture to illustrate the difference in buffer tubes between an A1, carbine, and Sully stock for days, and finally found one:

Ben, this should answer the question you asked me the other day that I couldn't quite answer.

 

The Sully Stock comes with the tube on the right. Most collapsible stocks come with the carbine tube. The rifle tube is on the left obviously. Like others have said, when you buy the Sully Stock, it comes with everything you need to attach it to a lower: spring, buffer, tube, stock.

 

Is the Sully stock shorter than the ACE Entry stock?

The Sully stock is about 8" long I believe, where as the ACE entry is a bit shorter.. like 7.5 or 7.25". I have no experience with an ACE, so don't have very much other info about them, but I do believe they both use the same tube. Sully also sells a 1" buttpad if you feel it is too short.

 

So is a Sully Stock an A1 Stock?

No - the Sully is shorter than an A1. Even with the 1" buttpad, the Sully would still be just a bit shorter than an A1.

Thanks for the info, Caine.
