Did some chrono testing (new Athlon chrono) on some 300PRC putting more time on the original rest.
24in barrel + can netted 2830fps avg (2810 box rating), new chrono bracket worked good.

Trimmed the extra material out of the linear rails and shortened the legs to fit a 250mm cubed printer. Files coming soon.

What printer do you use?

Currently using an Anycubic Kobra S1 combo, 270hr in I've had 1 clog that I had to sort out.
