I did not even know KAC made these… Not a FSB fan but I’m a KAC fan and these are interesting.
Carbine Length Free Float RAS

And it looks like they are dumping the stock by slashing the price…
A 7" LaRue is almost $100 less and I consider it to be a better rail since you don’t need a special super expensive wrench to turn the nut.
I like centurion rails. Cut off the delta ring and install without removing the fsp.
Too short. I have a LaRue 7.0 installed on a 6920 upper. Once you’re used to longer rails, the 7.0 just doesn’t cut it…at least for me.
I’ve seen people sell their children for the rifle length. Those mk12 cloners are a special kind.
A3 what?
??? It is a RAS not a URX, no special wrench needed.
This is the rail Larue knocked off for their rails design.
Any carbine length fixed front sight bus 'a frame"
Ya, they are.
I guess since these are not made anymore, and they are the original rail. It was a brilliant design.
Ya the PN has it listed at 6 7/8 inches, so I guess these are 7 inch. I guess if you don’t want to hack up your front sight buss it would be an option?
I’m personally not a fan of A frames to begin with, so I don’t know the hoops that might have to be jumped through.
On carbine-length systems (like the 6920), you can use FSP rails like the DD LR3 or RIS, Centurion’s 12" FSP, and Midwest Industries Extended Carbine handguard. They just have a cutout in the top to accommodate the A2. A few inches of rail space ahead of the front sight base is perfect for mounting a light, and it also is less limiting on where/how you grip the gun.
I just installed a Troy Delta on a carbine. Works well.
Got it, Kinda like the RAS MRE.
Not sure I understand the point in keeping the “A” at that point tho. Just seems like an impediment on a rail that long?
You’re right on the wrench.
LaRue ‘knocking off’ KAC has been mentioned, Daniel Defense knocked off the same design.
I know LaRue is not liked on this site, so I’ll just say that everything sucks and leave it at that.
I know what opinions are like, but Centurion, Fortis, and DD have the best FSP rails going at the current time.
Good luck finding one (12"). I wanted one but have given up looking.
I think they’re discontinued, but they still show up in the EE once in awhile.
The MI is a decent alternative if you need to work around a pinned muzzle device or simply don’t have the tools for a proper install, and the DD LR3 has a better profile, IMO.
Front sight cut out Daniel defense rails for $99 are far better
Where do find one of those?
Aim surplus had them for $119, but they’re long gone. $99 is insane.
