VSR hard to cock after upgrades

Recommended Posts

So my question is I recently upgraded my vsr with a new piston, spring, spring guide, and sears.  It clocks in at around 530fps with .2's which is right where I want it to be.  However my problem isn't the pulling back of the bolt, this faces normal expected resistance.  However, returning the bolt forward is much more difficult then on say my 550fps full PDI'ed maruzen aps2/98k.

 

I was wondering if this was a common thing?  Or is this a difference between 90degree trigger vs a 45degree trigger?  Or is there work that I need to do on it?

Yes mate, thats what happens if you above about 400 fps on a vsr, and why people fit 90 degree parts.

 

The piston sits at an angle when cocked and drags at the cylinder wall with the 45 degree sear, whereas the 90 degree parts keep it parallel to the walls with no dragging.
