This is my opinion and it hurts feelings-the reason the 700 has so much aftermarket is mainly for one reason-it is sub standard to begin with, people like to fiddle fuck with things and plenty of people have convinced them they have to. And not that a stock mil spec 1911 needed anything, it's the last two above that have made that industry thrive.
Ehhhh, I agree to an extent.
Back in the day the r 700 was fine. Great trigger, good wood stocks, good QC.
Then prices rose, manufacturing cost went up, lawduits from idoits happened and labour got worse and more expensive.
Winchester, and to a lesser extent Savage, didn't have to deal with this because they were dang near out of the game (Savage) or came out with a shit turn product and went out of the game (Winchester, there's a reason no one talks about the post 64 actions before FN started labeling their rifles as Winchester)
Remington adapted and still produced rifles, and those rifles suffered which certainly help with the aftermarket stuff, but for a long time Remington was also about the only option, Winchester stopped making firearms, Savage was dang near bankrupt and only produced a basic model 10/110 and let's face it Rugers are terrible.
I'd say put two period same grade m70 and r700 actions next to each other, or rather whole rifles and they'd shoot the same. And you'd be down to features.
