My friend bought a Pilot ACS he asked me to fix. The problem is that the bolt won't release, my first thought it was the battery or the solenoid. I put in a fresh battery and changed out the whole trigger frame, to a trigger frame that I know that works. The bolt still won't release. I tried a spring from my old Spyder Tl and exchanged it with the pilot and the pilot will work. Are the springs the same? I'm just thinking that someone put in a wrong spring I just wanna if I should order one.
