13" vs 15" rail for 16" barrel

Geissele has a 16". Wish they would do a 10 and 11".

You got that right.

The only 16" they make is the MK18 with the Arca-Swiss Quick Release System, their other rails are 15"

Wow. 7pages on which length handgaurd should one buy. This site is getting arfy lately.

I'm sure that the OP can appreciate a nuanced answer like "it depends..." and will ignore the mouth breather replies of "15 looks better!" or "13 for no other reason than that's what I have!"

I am a believer in less is more. When it comes to my M-4 too many add on's can induce a malfunction. Having said that, I like a long rail just in case.

Personally I like the look of longer rails. I run a 15" rail on a 16" barrel. If your inclination is towards the 15" and it's available you should go for it. I doubt you'll find any drawbacks to it once it's installed. Like others have said, you can mount accessories anywhere on the rail even if the last 2" of space are "wasted".

Simple for me...I shoot with arm extended to get close to end of 15" rail.

I generally hang lights on the FSB with a clamp-on Picatinny rail; works just fine, and the light is only installed as needed. Several carbines share several lights.
For looks, I prefer the Dissy, tho' the real issue is sight radius; I'm one of those antiques who likes irons. For irons, more sight radius makes a difference, whether with a FSB or mounted on the handguard.

I'm putting an 11" rail on an upper, just shaved the FSB down, and the front end is perfectly flush with the gas block. Midlength.

So that works too.
