I could've sworn I saw a 11" C4 rail but know can't find it. That would be ideal for my SBR.

Another question lol.

What would happen to a C4 rail if say, a good 3/4 of it overlapped my Lantac Dragon? 😁

First question is I don't believe the C4 was ever made in 11", I've seen both 10" and 12". The CMR is available in 11". Second question is that is a PWS rail that they don't make anymore, it also was not free float. Third question is I don't think it would be a good idea to overlap a muzzle break, to much side blast. There some pics floating around where the side blast has actually ruptured the handguard. If you're wanting a quad rail for an 11.5" barrel I would recommend a Knights Armament URX II 10.75".

No such thing as an 11" C4.

If the ports are blasting into the interior of the rail, I would not do that.

Damn I swear I saw one lol. Thanks guys. May just go with the C4 in 10" so I can just use my existing bbl nut. Easier swap

Just goes to show you why you need to "shoot the gun" This was posted on M4c last year. The OP admitted it was his fault, and learned a valuable lesson.

However, Fortis stepped up and replaced his rail, even though it was his fault. Now that's some customer service.

Unless it's a Linear Comp or a KX3/5 DO NOT place muzzle devices inside of a handguard.

That looks like a BCM comp too. I figured it was a bad idea as the dragon has some serious blast

I really want a C4 but that'll make my Arisaka mount obsolete. I like the Fortis Rev as well and the mount will work but I'm just not sure I trust it. Perusing the interwebs I've come across some not so good stuff concerning the Rev rail.

The REV rail is Good to Go. What are your concerns?

The C4 is also solid. If you want to use the Arisaka Mount, you can either throw it in the parts bin for later, as if this will be your last upper...

Very true as I change my mind way to often. Read some fitment issues and the rail shifting after some use.
