Time to rebuild my Upper. Need rail advice.

This is the way I'd go. I am not a fan of metal handguards because they are hot in the summer and cold in the winter and adding plastic covers increases weight and girth. But I got the chance to handle a Colt CCU with the covers installed and the setup was light with a surprisingly small cross section that's comfortable in my hands. Of all the aluminum handguards I've tried, this is the only setup I like enough to buy. In fact, I'm waiting impatiently for the group buy for the Centurion handguard to go through that Stick is so graciously sponsoring for us.

Agreed. I've been through a lot of hand guards in work and rec. I wasn't a sceptic of the Centurion, but didn't give it much thought as there are so many others on the market I enjoy. The other day I got to feel one for the first time and it had that "finally" feeling to it. Finally, a rail I can't find a single thing about it I would want to change. It feels slim, solid, and something I wouldn't hesitate to take into combat. It truly is worth considering.

Just FYI on the BCM rails, V7 offers titanium cross bolts and barrel nut. It will drop the installed weight by 1oz.

This thread really applied to me, got a new midlength upper and was in a similar situation to you Greg (going from two DD omega FSP's and wanted something lighter weight) thanks for getting me what I was looking for!

To the OP, sounds like a great build. Please post pics when you get it back. Also for those interested, I had my SF3P silver soldered to my 14.5" SOCOM barrel, and it turned out quite nice. If you are a stickler for aesthetics, you may want to take into consideration the discoloration of your barrel that may occur near the soldered area. On my barrel the finish turned a slightly bronzed color near the flash hider. Initially the discoloration bothered me, but after shooting it I don't really care anymore, as the discoloration has not affected function at all. In fact it's one of my more accurate barrels.
