LowLight..... Question... when reading the story on the rifle Chris Kyle used when he was a sniper. He gave what he liked and so on. Is it up to each shooter to build their own rifle? or does the military provide it? He said he loved NightForce because of how durable they were. Just wanted your insight to this.That is an old story,
the S&B being used was a hybrid of Premier and S&B, when they divorced the USMC went to Premier. Since Premier really does not exist I am sure they need a new scope about now, especially with the changes in the industry.
The USMC has not bought new S&Bs for a while, which is why you see both S&B and Premier and recently I know they bought some NF scopes
But the stories are a mix of old and new. They didn't want to replay the contract process when the two divorced so they opted to just change it over to Premier, we all know there is no Premier now.

Choices in scopes require a process,
that takes a long time, they have to solicit requests, test and evaluate, it's not as easy as saying,
We want X Scope....
That only happens on small scales, drastic changes or large Marine Corps wide changes have to go through contracting. Now they can write the solicitation so it favors a specific scope, but they still have to accept competing offers from other brands. They cannot say, We want Nightforce, they have to say, We want a 7-35x scope that includes the following specs

I'm sure Ilya (@koshkin ) can explain it in better detail, but as I understand it, the SFP have fewer parts and lenses, and fewer parts in the same real estate means those parts are more easily built/designed to be more robust/durable. I think Ilya did a video a few years ago on FFP scopes and how they work. Within that video he mentioned something like a minimum of 11 lenses in a FFP scope, vice something like 7 in a SFP scope. Also, he mentioned (IIRC) some FFP scopes have up to 19 lenses. That's a lot more different things than can be bumped, busted or bent. Again, with all those parts crammed into a 34mm'ish tube, it really limits how thick and robust some of those parts can be (and still fit inside the tube).
I'm hoping ILya can pipe in and clarify, as my memory ain't what it used to be, and it's been awhile since I watched that video...
