Need a measurement between the receiver and the flash hider where is that slight play for the barrel to free float. Someone was able to get a measure using a set of feeler gauges. .015 and a tight .016 were reported to me, but I wanted to see what others get for a better sampling. Any one with factory free PS-90 nonsbr might be able to help most.

The barrel has a counter spring under the flash hider and is torqued to if I remember around 26 to 30 ft lbs.

30-35 ft/lbs.

Yep, completely know that. Just seeking knowledge though on that gap...

If your parts are correct and you assemble it properly and torque it to the specs listed you have the right gap.

I just checked 6 at random and they're between .018 and .024.

Just curious but why do you ask this question?

Look up my post history with a HDD barrel debacle. Also thirst for knowledge...
