Looking for suggestions for a extended carbine rail that will install around a FSB and have rail space past the FSB.  Looking for drop-in with delta ring.  Currently have a P&S RAS installed and my WML placement doesn't agree with new rifle racks.

Not drop in, but Centurion C4 12 FSP uses a GI bbl nut and is kick ass.

For this, you will have to remove the Delta ring assembly. It can be cut off, but you have to be extremely careful in doing so. It is that or disassembling the entire barrel assembly, including removing the FH and FSB. It does use the standard barrel nut.

^This or the MI, I've had both, I prefer the Centurion well worth the coin, sold the rifle, which I regret, but I still have the MI on a Colt, love it, just as good, easy to install, and just as efficient as the C4, although I think the C4 is just slightly better, but not by much!

Almost positive DD made one that retained the factory Delta ring.  Good luck finding one.

If you're not a Troy hater the Delta seems to fit your requirements.

Here's one on my SP1 with a 14.5" Colt SOCOM bbl.

Far from a drop-in, but the best one I ever had was the APEX modular cut-out.  I am a huge Centurion fan, but I loved the APEX even more.

You could go Force Recon Marines style and add a ERGO M4 rail extension. I'm amazed at how solid this thing is. Mounts directly to the FSB. About $85 and works with everything else you already have.
