Evening all,
Looking for some clarification on DST trigger operation on a 1518. Today while hunting I had an opportunity for a shot, set the trigger and the shot opportunity passed so no shot. I then un-set the trigger using the procedure below. After finishing the hunt I pointed the muzzle at the ground and pulled the safety off to open the bolt to remove the live round from the chamber. While moving the safety to the off position the rifle discharged. I thought I had bumped the trigger in this operation but then though no, the un-set trigger weight is 3.5 lbs and I know I did not bump it that hard (if at all).
After unloading I closed the bolt, set the trigger and with the safety on pulled the front trigger to un-set it. Loud click, should be unset, slowly eased the safety off and about half way to the off position the firing pin dropped with no manipulation of the trigger. Does it every time.
As received the set trigger pull was about 8.5 oz, a little light for me as I primarily hunt with it, so I raised the weight to approximately 10.5 oz. Passed the bump test with no problems.
Here is how I understood the operation of the Anchutz DST to work:
1. To fire unset, just pull the front trigger, breaks at around 3.5 lbs.
2. To set the trigger, pull the rear trigger, rear trigger will not fire the rifle, you hear a good click and now the front trigger is "set".
3. Once trigger is set, then front trigger is much lighter at the break, pull front trigger to fire rifle.
4. My understanding is that if you set the trigger but do not take the shot and you want to un-set the trigger to make it safer, then with the safety on you pull the front trigger, you will hear a loud click and the action will now be in the un-set mode and to set it again all you have to do is pull the rear trigger again.
From a safety point I always set the trigger with the safety on, and only take the safety off when ready to shoot.
I use the same process outlined above to un-set my CZ SST rifles and have never had an issue.
I had contacted another RFC member who I felt was pretty knowledgeable in Annie DST operation and asked for advice. He gave me the following procedure to un-set the DST:
1. Ensure rifle is on safe.
2. Hold rear trigger to the rear and keep it there.
3. While rear trigger is depressed, pull the front trigger and then ease off the pressure on the rear trigger, this will un-set the trigger mechanism.
I tried this on my unloaded rifle and it does work. BUT!
1. Need two hands to complete operation, seems very awkward.
2. When I first received my rifle I unset it by MY method and it did not fire when taking the safety off until today. Something seems to have changed.
3. Is there a mechanical reason WHY you cannot/should not unset the rifle with the front trigger?
Even if the above method is THE way to unset an Annie DST, I'm SURE that someone has pulled the front trigger by mistake once set with the safety on and I find it hard to believe the firing pin can be expected to fall while moving the safety to the off position.
Anyone have any input? I'm quite mechanically inclined and not afraid to dive into triggers (have in the past) but before doing so I like to arm myself with as much knowledge as possible to promote a positive outcome!
Thanks in advance for any and all advice!
Cheers!
Wade
Any advice or can you point me in the right direction as to who to talk to on RCF? I'm mechanically inclined and am not afraid of diving into the trigger. Just thought I would ask someone who has more knowledge than me to shorten the learning curve!
Thanks
