I got my 4 port sporter version finished up. They are .73" OD 1.725" OAL and weighs under 1 oz. this design only accommodates 1/2-28 thread.
They are designed to be able to be turned down to .625", and can be bored up to clearance for a .308.
I also just did a run of the 5/8-24 3 port slab brakes this week.
Right now I have the 3 port 5/8-24 slab brakes available for $150 each.
The 5 port self timers in 5/8-24 for $180 each.
And these sporter 4 ports in 1/2-28 for $100 each.
