Ruger m77 drop in trigger assembly

[WoodchuckAssassin]

All I can find for a drop-in trigger assembly is for a M77 MKII or M77 Hawkeye...but my rifle is the older version from the 70's.

Can I drop in a MKII trigger in my older m77 rifle? If not, where can I find a trigger assembly that will fit?

I also realize that the m77 has an adjustable trigger, but after playing with the adjustable screw, there was no difference in the trigger.

Thanks for any info you can pass.

I believe the part you want to replace is the factory sear for those 77s with a tang safety. You'll keep the factory adjustable trigger itself but the aftermarket sear will improve feel. Call Rifle Basix: (704) 499-3087

Good advise.

The adjustment screw should take up all the sear travel. It should be adjustable enough to even make the rifle unsafe (will fire upon closing bolt when adjusted too far). You should be able to easily attain a 3lb trigger on the tang safety model.

Timney does make a full trigger assembly for the tang safety Ruger 77. I installed one on my .257 Roberts 2 years ago. It's hard to find the trigger assembly online, and even more difficult to actually install it - the safety link rod in the Timney is heavier wire, and the bend in it requires taking some wood out of the stock along the left side of the receiver. In addition, there is a cap screw head in the bottom of the Timney trigger assembly ahead of the trigger itself, that requires a little wood removal. The latter can affect the action - if too much wood is taken out, the action can "bend" a little when the bedding screws are tightened. This WILL affect accuracy.

While the solution may not be as elegant, the Rifle Basix sear replacement is a LOT easier to do, and makes for a better trigger than the original.

Thanks for the advise! I'll give that number a call and see what they might be able to do for me. I have a good gunsmith who says he'll give me an action job for $100, but if there's a way to save a little money I'd rather do the work myself. Is it difficult to get the action of the m77 apart/back together? After taking apart my Ruger 10/22, I can't imagine the m77 being more difficult than that. Haha!

I THOUGHT that playing with the adjustable screw would work, but after taking the screw COMPLETELY out, the trigger pull was still a slightly heavy 5.5 pounds - exactly the same as it was when the screw was all the way in. I also tried changing the overtravel screw, but that didn't make things any better so I just left it alone.
