The platform can be made to shoot much better. It has a 48. WTF.

coil spring that’s to soft. Shorten to 40 coils add 1.125 delrin plug for space and Re guide with longer tighter guide. Re seal with tighter seal,( I made mine as all 27 mm seals are junk parachute ) and depending if it’s adjustable port set at 3.3 mm to 3.4 mm. Replace front two trigger screws with longer and the gun will transform into a calm 17 to 19 ft lb shooter.
The Quattro is a great trigger. Every bit as good as a Rekord at 1 lb and up as most hunting guns should be.
My re barreled .25 Turkish Tommy ( same gun as a 95). Is doing 17 ft lbs now
I may Re barel it again to .22.
I hated the .177 it was .. not shot wise just hate the caliber.
