Remington just doesn’t have that many interesting guns. There are a ton of firearms manufacturers in the last 20 years. I’m guessing the AR-15 market alone is billions in revenue.
The problem is that even their basic offerings have drastically declined in quality. If you make plain oatmeal, you'd better be really, really good at it, or else you have absolutely nothing going for you.
The Mk13 which is expected to replace the Marine's scout snipers M40 is 700-pattern, just not built by Remington.
You're going to be right soon, just not yet.
Likewise, "The Military" is still using Rem 870 and Mossberg 500 shotguns. The "other military" that is, the IRS, Deptartments of Interior, Energy, Education, and everything else; their SWAT teams all use the Rem 700 and 870.
