Lyman GPR Trigger

[Msplcdyankee]

My Googlefoo is broke. Can anyone tell me the thread size for the center adjustment screw on the GPR Lyman uses. Mine is run all the way in and the trigger is still heavy when set.

Hello Msplcdyankee,
I'm not sure of the thread size but, it is a tricky one. A friend of mine gave me a couple he ordered off the internet. I believe they are metric or European sized threads. They are longer than the original that comes in the rifle. The screw that comes in the rifle is really short. I believe you should be loosening the crew to make the pull lighter. Give that a try to see if that helps.

If you are able, possible next upgrade, I would suggest getting a set of the R.E. Davis Deer slayer triggers for your rifle. I have 2 GPR's and put a set in each. My opinion they make your rifle soooo much nicer to shoot. Its like a completely different rifle. They drop right in the stock. I did not have to adjust anything when I put mine in. They run between $50 and $55. There are some threads here on this sight with more info on them if you would be interested.

If you have the original screw, the folks at Ace hardware or some other hardware or automotive supply place should be able to tell you what the thread size is.
Another place to check if one is available might be a clock repair shop that specializes in fixing old fashioned mechanical clocks.

Maybe they will even have a longer screw available for you to buy?

I think the people who make the guns Lyman imports make that adjustment screw short intentionally so that people won't set their set trigger too close to the release point.

Setting the screw wrong can cause the gun to fire accidentally from just a little tap on the stock.

If you do get the longer screw, with the hammer or cock in the fired position, set the rear trigger.

Then, screw the adjustment screw in until the rear trigger suddenly releases.

After that has happened, back the adjustment screw out by one full turn.
In this position, the trigger should be set as lightly as it can be while still being safe.

Oh. If you do buy a longer screw, be sure to tell us what the actual thread size is in this post.

I ordered a Deerslayer trigger for my GPR today. I have never been happy with the original, and I like a good trigger on my target rifles. For $61 delivered, it is a pretty inexpensive option. Hope it is a good as people say.

Ace has'm,, Metric-2.5x8
It's plenty long and you could cut some off if you want/need,, but the next length down is as short as the factory.

Thank you so much for the info.

I'll be real surprised if it's not. On rare occasions I've had to make slight adjustments to the stock, but most times it has been a straight drop-in job. The results have been so much of an improvement that I won't even consider shooting a GPR (or a TC Hawken) without the Deerslayer.

I have had them a few years on my.40, thinking about getting two more for my other two gpr. They are really an improvement.

I got a Davis Deerslayer for my T/C Renegade last week and it does really make a difference. My stock double-set trigger wasn't too bad, but the Davis is much better. Only a very minor internal wood alteration and it fit perfectly. I'm happy.
