RonnoThat sounds like it will work as long as there is enough room so the spring is not completely compressed.For the locator in the sear what do you think about drilling and taping a 6-32 or smaller hole and using a screw withmaybe a washer under it?
That brass spring holder look like it should work if it is not sticking out on the top side of the valve body where the delrin wedge did. Will the brass be glued in place like the delrin wedge?
You said something about sear bounce, I don't know how that happens but something was happening when I first put my rifletogether and pumped it 4 times and was getting a loud pop each time I cocked and pulled the trigger for 3 or 4 times.
At this time I believe that the problem that I am seeing is caused by the sear, but who knows.I installed a sear that is different that the original.The sear only moves until it hits the top of the valve body, I removed some metal from that point on he sear and the rifle worked fine at 6 pumps but not at 8 pumps, only tried it once at 8 pumps.I am going to wait for the brass locator from Ronno so I can try the rifle with the original sear, If there are still problemsholding air we can look for other things.I am happy to be a small part of this process.
One gun I would like to test this in yet is a Barra 1866, not sure if this will be compatible, but this one has a super stiff crunchy trigger, needs help bad.
