I am having a qty of short bbls machined to work with either the original rec or the new receivers I am making for the px90 project and want a little input on what twist rate would be preferable , 1/7 or 1/9
I would buy a barrel like Esteves is talking about if you can keep close to the $300 range. Essentially, I want a 10.3 barrel with standard .5 x 28 threads with a perm attached suppressor shroud to keep the PS90 non SBR OAL. Shroud would need to accept standard 1.5 inch 5.56 suppressors. Is that possible?
