I can say mine was a bit stiff when new, but that vanished

rather quickly with heavy loads... makes you wonder.

After cracking several forearms through the BB screw, I quit the 300+gr, 2000+fps loads. Those forearms are thin, especially with the overlarge mag tube. Stepped down to 1800fps and the last already-cracked forearm hasn't gotten any worse. that's about 2-300fps above where I run my 45C 92s. Of course, that sort of ruins the dual gun, same ammo concept unless you load down your FAs.
