I used to run the old spring in my nt10 and it shot amazingly. Now that I have the bumper sorted out I'll start messing around with the lighter spring. In combination with the adjustable manifold this could prove to be interesting.
I've been doing some thinkering and some experimenting and I'm almost sure that most of the `kick` of the NT is in the rearward travel of the bolt.
I noticed that the the bumber/limiter of the bolt on it's rearward motion is the insert. The insert is the stop, when the bolt goes back it stops when the insert hits the tip of the plunger.
I tried a oring in front of the blue oring on the plunger, then the bolt stops when it hits the oring, which is softer than the material of the insert.
Also, have you ever saw a ego/geo detent? I did cut it's tip and glued the rubber piecie on the spacer rod, so the spool hits something softer.
I've played last weekend and the gun was really great, soft and quiet. I'm playing again tomorrow(holiday here) and if it works okay again I'll send you the pictures of that I did.
From what I have been thinking/seeing/experimenting, the spring makes little and maybe no difference. It seems to me that it's just a this work/this one does not work situation and that little dialing makes no difference at all.
Sorry if at some point I did not make myself very clear, english is not my native language.
