If the latch rod latches in the trigger off the rifle, Build the action minus the spring ,see if it cocks if not, make sure your guides aren't coming together ( have you put a washer behind the guide ) or maybe your pre load washer is too big on diameter and wont fit in your piston ( or the bore of the washer is too big and is sitting eccentrically on the guide)

Adding pressure to the 1st stage and weight screws fixed the latching problem.
The rifle will now latch every time.
It still needs some more adjustment because the safety pin does not always reset.

Thank you for taking the time to reply to this post.
You have educated me on the TX 200.

Thanks again.
Kelvin

Now that the problem is fixed, you can adjust the trigger for creep. If the second stage breaks crisply, you can forget this advice. I turn the rear trigger blade screw anti-clockwise about 1/8th to 1/4th turn then cock and fire the gun. If the gun fires before you get to the second stage stop, adjust it back to where it was because it's already good. If it still has a second stage, repeat the first advice of turning anti-clockwise and firing until the second stage goes away. At this point, turn the screw clockwise 1/8th to 1/4th turn and you should have a very nice let off with no creep. One thing that may happen is the trigger may seem to catch at the end of the first stage travel. If it does, go just a fraction more clockwise. You will soon realize why the AA CD trigger unit is the airgunning world's premier sporting trigger.
