Tuning the AirArms CD Trigger

[Ferrets Bueller]

None, its really easy, just take your time, following the guide.

A very worth while mod and just two things to add

While you have your pride and joy apart you could also think about mirror polishing
the mushroom as well, you will notice after you have how much smoother it will cock
and its quieter as well.

Secondly while you are there with your sears and block in pieces give the adjusting
screws a polish as well (the ends that is )it helps your fine adjustments no end.

You never need an excuse to mirror polish your mushroom! Just don't get caught.

Tried this with my TX200 this week: stripped the trigger, polished the contact surfaces to a mirror finish and re-lubed with a bit of moly grease. I then decreased the travel of both stages bit by bit, resetting dry-firing the trigger block as I went. I found that by doing this, I was able to get the trigger light but sharp with a clear second-stage despite it being light, and no creep or "sponginess" to speak of.

The pressure feels different to when there's spring pressure on the rifle but it gives you a good idea of the stages if nothing else - set the trigger pressure a shade lighter than you'd want it and then put it back in the rifle and try it out. Remember of course to test the rifle by loading it then (whilst pointed in a safe direction) giving it a few firm smacks from different directions to see if knocking it will set it off. Obviously you don't want the trigger so light that this occurs!

I think it's worth the hour and a half to two hours I spent on it, so will be doing the same to the trigger unit on my Pro Sport soon.

Hi,

I have polished my CD trigger, but I'm not happy with the result. The first stage is not entirely "clean" and the trigger tends to get stuck just at the 2nd stage if the trigger is set at low pull-weight.

As I see it there can only be one contact point where the problem is. Since I have a rowan trigger with hardened screws and the metal piece where those screws make contact is mirror polished the problem has to be the other contact surface. Have i taken to much metal off (we are talking just the machining marks)? Are the edges to sharp? One theory i have is also that the surfaces are not entirely aligned with each other.

What do you think?

Try turning the rear trigger blade screw in(clockwise) 1/8th turn. This helps at times. It sounds like you have the travel after the first stage completely dialed out which may cause the sears to catch when they try to reset. I actually set my guns up the way your trigger is described. When I take up the first stage and try to release it the blade dangles. I use my guns for target work only, but if they were for hunting, I would add a little to the rear blade screw as well as the weight of pull screw.
