I also posted this at the "rifle" site in the firearms section.
But, just in case some of you go here, but not there (which I doubt), Here's
something for you Nagant lovers.
Timney triggers is now producing an adjustable trigger for the Mosin-Nagant rifle.
It also has a side safety in it (like the Mauser featherweight deluxe) so you don't have to fool with that horrid military bolt safety anymore.
Timney sells them retail for $94.95.
I use timney products, as I'm sure a lot of you do if you work on rifles, and I have found all their tiggers I use to be exactly what they claim them to be, and excellent quality.
Just put "timney triggers in "search", and your almost there. The new trigger is shown on their home page.
