I have a CNC Billet Aluminum tube fed trigger guard for a Winchester model 77. I have then polished or hard black anoidzed.
If it is a newer model it should be right in front of the trigger guard.
It is very easy to adjust the trigger on a Model 700 Remington. Remove the rifle from the stock and there is 3 small screws you can adjust. One is for the lbs. of trigger pull, which be careful you don't make it so easy it's a hair trigger and could go off just by the jar from closing the bolt. The other is to adjust the length of trigger pull.
Winchester made the model 1873 rifle and the model 1876 rifle,but did not make a model 1875 rifle.
Winchester but I'm not sure exactly what model. The Winchester has a cocking lever built into the trigger guard. His rifle had a modified cocking lever that was larger and allowed fast cocking.
Type your answer here... how do I adjust the trigger on Remington 799
I am not aware of one on today's market.I have never heard of one for this model of rifle.
The rifle was produced from 1904 to 1923, originally known as the Winchester Thumb Trigger Model. In 1920, the rifle was renamed to become the Winchester Model 99, and it stayed that way until 1923 when the rifle was discontinued. Value is heavily dependent on condition, but should exceed $1,000. You will need a hands-on appraisal for a better answer.
A Winchester Model 70 is a rifle.
There were a few that do not have a standard trigger, but use a THUMB trigger. Do a web IMAGE search for Winchester thumb trigger rifle, and you will find it.
