I routinely take ALL my new rifles except Sako, Tikka, and TC ICONs to a gunsmith to for set up to my shooting style. The three mentioned above are easily adjustable with a small allen wrench…even for a mech challenged guy like me!
I have had Mark X Pro triggers on 3 of my last 4 Remington CDLs and my LSS .280. My Gunsmith comments that ALL factory triggers need de greasing and de gritting. While the polish and finish on the Mark X parts are nice, it is not a huge improvement over the std trigger. The gun manufacturers are finally getting over lawsuit phobia and producing some better triggers but most of them still come way too heavy for accurate (MOA) shooting.
My big game rifles (deer, elk etc) are set at 2.5-3 lbs with no creep or overtravel. My 22.250 is aet at 2 lbs for shooting small objects at over 300 yds.
All Std Remington triggers are awesome when cleaned and set by a gunsmith…a 25-30$ task.
