I bought this hard rubber recoil buffer, it looks like it could soften recoil, but this thing is .780 thick and I'm worried it will not let the roller blow back bolt go full travel and damage the receiver. Any advice will be greatly appreciated.

  I'd contact PTR and see what their thoughts on running a/this buffer are.
  
  Personally, I'm not an aftermarket buffer fan. One more thing to break and cause reliability problems.

  If the gun is designed/assembled right to begin with, it shouldn't require an aftermarket buffer, right? (Which kind of goes to what the manufacturer is likely to say if you ask them this about this. . .its going to be "we think our buffer is OK", or "we don't recommend using an aftermarket buffer".)
  
  The biggest issue with buffers like this is that they tend to disintegrate with (normal) wear, then they shed off material inside your guns action that can jam the gun (including the whole flipping thing breaking off). I think the opinion of most authorities is not to use these in any fighting/defensive gun for that reason.
  
  On your actual question, it seems implausible to me that a rubber buffer that slightly limits the bolt travel is going to damage the gun. You'd also hope that whomever manufactured this buffer knew what they were doing and wouldn't put one out to market that was likely to damage the gun it was designed for.
  
  So, while I haven't tried this, I don't think this is likely to destroy your gun. On the other hand, you're dealing with a .308 with a delayed roller action to begin with. . .I'm also skeptical that you're really going to have any significant difference in recoil. My experience with these sorts of things is that they can decrease the metal on metal "clack" during recoil, and tame the associated shock a bit. But there is only so much something like this is going to do for you. If you're really bothered by recoil/action noise here, maybe an AR-10 is a better fundamental choice.

  Thanks for the advice, this is made by buffer technologies.
  I did a search over at HK forum and found a thread on this particular buffer that confirms my worries.
  
  Here is one of the typical replies to the same ?
  
  "From my personal experience and from other posts I have read in the past I do not recommend using the Buffer Tech buffer.
  
  These buffers make the original buffer useless. Also they do not allow the bolt carrier to go as far back as it is designed to. This throws off the geometry of the operating system and causes additional stress to the rifle. These buffers can cause cracked stocks and roller marks in the receiver.
  
  I put one of these buffers in my Cetme years ago and the first day out it cracked my wood stock!! The recoil was noticeably more harsh with the Buffer Tech buffer than with the buffer the rifle was designed to use" C
