I have one host that I want to keep as short as possible while unsuppressed without it being an SBR.

Is there any downside to a machinist slicing off the 2nd and third ports on either a saker or Specwar brake to create a single chamber brake for this one specific host?

The first ports are doing the majority of the work as far as aiming the blast anyway. Reducing recoil on a semi auto is not even necessary to be honest so your idea sounds fine to me. Muzzle devices on semi auto AR rifles are more for looks and protecting the barrel crown than actually making the rifle controllable.

A hacksaw or sawzall and a belt sander would make it fairly easy to do yourself?

I worry that the leading portion of the brake might have a role in preventing baffle strikes in some circumstances.

A call to SiCo might answer the question, but I think I would cut the barrel, pin and weld the brake for a barrel length of 16.25" (an extra .15" just to make sure...) I looked at a similar option for a short, handy, easy-to-travel-interstate-with suppressed rifle, and iirc, your barrel length before brake or flash hider ends up around 14.7" assuming you use the Specwar 7.62 flash hider.

[FWIW, I hate brakes and see no reason for a break on any rifle, let alone an AR 15 with the very limited powder capacity/bullet weight combination of any cartridge that will fit. Perhaps the only practical use, imo, would be on a full auto rifle, but I have fired a full auto 5.56 rifle equipped with a flash hider and muzzle rise was pretty easy to control after a couple of tries.]
