Congrats on your Savage Axis
Have over 3,200 rounds through my 223 a few hickups along the way - it was the best $450'ish taxes in I've spent on the rifle.
Never had a firing pin issue
Extraction issue started after about 1,000 rounds bought a new bolt head no issues since then
Magazine still functions as new
Didn't do anything to the factory stock
If I ever burn out the barrel - a prefit barrel will be installed (same profile/twist rate)
To each their own I guess -
My axis 223 package has 2500+ rounds and never had a issue. Accurate but the trigger sucks. Spent most of its life bouncing around on a quad ,tractor or truck. Mostly used for ground squirrels but with 64 grain WW PP has cleanly taken 7 mule deer bucks.
