Well, just picked up my new Ruger MK 77 "All Weather" in .308 today (thanks ARmaster!).  Although, I have not had a chance to shoot the rifle (beside dry-firing with snap caps), I have become spoiled with my Savage's new Accu-trigger and this Ruger's factory trigger will not suffice.

I need some recommendations for good adjustable aftermarket triggers for the Ruger or help on tuning the trigger myself.

TIA

I put a Timney trigger on my wife's MKII compact in .308   It's a nice trigger (about $80) and was fairly easy to install.  The hardest part is getting it to fit with the safety, you have to remove enough material so that the safety works but doesn't allow enough sear movement for the striker to fall.  

quoted from their web site:

The Timney RU77 MKII raises the standard of accuracy and helps you to achieve the marksmanship that you know you are capable of. The RU77 MKII provides trigger pull adjustment from 1½ – 4 pounds as well as over-travel adjustment. Trigger pull adjustment is easily made without removing the stock. The trigger and sear are made from 440C stainless steel, the best material for both hardness and corrosion resistance. All contact surfaces are hardened, precision ground, lapped and polished. Available in both right and left hand models. Will not fit the VT model. Not for the Ruger M77 (old style w/ tang safety).

Spec-Tech sells one. I got one for my Varmint and it went in no trouble at all.
