MK 16 handguard

Google search didn’t turn up anything. Anybody know if the Superlative Arms adjustable gas block fit in the Geissele MK16 handguard?

I can't say without a doubt but it should, I run a Jp adjustable block under one of fine and it clears that fine. The handguard that I use to run with that block was a MWI and it clears the superlative thats under it now. You should be fine.

I also don’t know for certain, but I’ve got an SA block under another brand’s slim rail and it clears no problem.

Yes it does, I just built a 16in SPRish with a Craddock barrel and used the SA block.
Set screws, I don't think the clamp on will work.

It does. I just put 2 15" mk16 on builds using SA gas blocks. All are .750" fwiw. The .750" SA GB fits under the mk14 too (a few of them in the safe). As mentioned above, set screw versions.

Great! Thanks for the info.

I run both, they fit.

however, the MK16 (or any of the geissel rails with the 4 anti rotation tabs) does NOT fit with a larue stealth upper receiver. Even though both claim to be "mil-spec"



I was super pissed. Then I realized I could use that rail on another project and ordered a forward controls rail and that should fit.

Maybe I should clarify my earlier post. The .750" SA set screw GB will fit under the mk14 and mk16 but the handguards may not work on all uppers. I have run into both rails not fitting "thick" uppers to include a CMT I just installed a mk16 on last week. A small amount of measurements and application of a fine file and it fits fine. Some may not want to use a file on a $$$ handguard but me and aluminum black liquid have a long history.

Looking at the Larue above, yeah that won't fit. I bet it did piss you off.
