Trigger Tech now has two models. One is a standard replacement hunting trigger to replace the Remington 700. Trigger Tech will adjust from 1.5# to 4# and second another model that goes below 1.5#. They use a roller between the trigger and sear. No two pieces of metal scraping directly between the trigger and sear. Here is a link to their web site:
https://triggertech.com/collections/bolt-action/products/rem-700-primary-trigger I got turned on to the Trigger Tech triggers about 6 months ago when one of the top Remington 700 action clone manufacturer said one of their larger buyers for their custom actions had gone to the Trigger Tech triggers. The story goes that the Canadian Army sniper units have gone to the trigger for their sniper rifles. One of their sniper instructors had opened up a Trigger Tech trigger, filled it with sand and put it back together with sand still in it. The rifle would still function not at 2# but now at 4# without any other problems. The Trigger Tech trigger is a one piece unit, either with a safety or without a safety lever - your choice.
Brownell's list the trigger on line, without the safety lever. Directly from Trigger Tech you can get a one piece unit with trigger and safety as a complete drop in!!! Really nice!!!! I called one of the gunsmiths at Brownell's and he said he did not know a lot about the Trigger Tech trigger. I asked him how Trigger Tech triggers Brownell's had sold? After a few minutes, he came back on the line and said, "My gosh, we have sold over 750 units in the last 6 months and not one return! Guess I had better get a unit and look at it closer."
I have four of them now. They are not a Jewell, but are better than a Timney or Shilen. But for a hunting trigger in wet or dusty conditions they are the "cat's meow"!! What I like about them is they are all one piece, drop it in and no fiddling with a Remington 700 sear that requires 3 hands to replace. Adjustment is from the outside the trigger guard with a small hex head wrench. The adjustment is a click adjustment (like the click adjustment for windage and elevation on upper end scopes) that equates about to one pound per click. I check with a Lyman Digital trigger guage and one click does equate to about an ounce. Lots better than turning a screw, check, adjust, check, adjust, etc. Really well designed and about half of a Jewell.
