Can anyone confirm if gate lock is compatible with the 5.56 Vortex flash hiders?

It is not.

We make a 3 tine flash suppressor that works as well as a Vortex, and we make a closed tine flash suppressor that I like better but that isn't quiet as effective.  So there are some options.

As previously stated, it is not compatible. But it could have been. A while back (2-3 years? something like that) @Green0 drew up the necessary changes to make the Vortex G6A4 compatible with Gate-Lok suppressors, I was in contact with Smith Enterprises and about to order 100 of the modified units...then they ghosted me without explanation, so that fell through.

Big fan of Griffin's 3-prong stealth flash hider though. A few of those and a bunch of Wilson A2s are on pretty much all my stuff now.

Yeah we tried.  I had made one flash suppressor with them before, but it was for a suppressor that wasn’t successful so it was a one time thing.

I’m sure they have had a mixed bag of custom projects and that may get to be sort of undesirable business.

I know we are close to "the end" of the NFA, but has there ever been any thought to making an A2 extended compatible gate lock? Or are those dimensions just not reliable enough?

There hasn’t been any thought- the front ring isn’t where it needs to be to index the front support.

Y’all had a longer closed tine model that had a raised ring like a half inch back from the mouth, but it went away with the introduction of the Nato mount cans, which they were not compatible with. A couple other Gate Lok mounts also went away.  

Any extended mount compatible with both has to have open tines up front to fit around the stops in the Nato adapter:

I think all current Gate Lok devices work with both mount types. Not certain of that, because I haven’t checked all of them.

The m4sdk for sure in the am line wouldn’t be compatible anymore with that.  

The longer flash suppressor would be a little better, but probably it would only come back if some kind of contract requested it.  

The short closed tine flash suppressor works pretty good, and fits all cans.

We are considering playing with slm designs on a hybrid muzzle device although there is very little room to do much in the tiny footprint.

That makes sense about the upcoming shorter K can. The fact the old M4SDk can fit so many baffles and also accommodate a 2.25” mount is kind of a marvel.
