My Google-Fu is failing me. AR-15 gurus assemble

[SaintsNSinners]

So Im looking for a new handguard for an AR-15 build and for the love of me I cant remember who made the rail I used to want.

It was for a carbine length gas system (believe they made mid length to) Basically it free floated to the FSB and stopped with rails on the side but a cut out for the FSB and bayonet lug.



Anyone know who made a rail like this?

Daniel Defense?

I have seen free float rails with FSB cut-outs by:
DD (fixed rails)
MI (fixed rails)
Vltor (configurable rails on CASV)

Just saw another thread with a Centurion link from Bravo Company that had the FSP cut-out and a taper on the bottom for the bayo lug.
Here is a link to the carbine one.....

How about this one from Daniel Defense.

If you're looking for a 9" or 12" handguard / quad rail that will fit a carbine then you'll need the cutout. I bought a couple from Valhalla Tactical Supply, but after I bought them I found out I would rather have changed out the front site for a low-profile gas block and the cutout would have been unnecessary. That's because I use Trijicon scopes and I now need a riser if I don't want to see the front site. If you're looking for a carbine length you won't have to worry about a cutout for the bayonet lug. Either way, there's a lot to choose from on midwayusa.com or at Valhalla Tactical Supply. I bought one Troy in FDE and one black GG& G. Daniel Defense cost over $100 more, but that's what a lot of guys prefer.
