Remington hasn't been good or put out anything worthwhile for 30 years. Other then their ammunition.
As horrible as Remington management has been over the past decade or two I would have to disagree with you on the worth while of some of their products even if they ultimately killed them due to QC and support issues. In the past 20 years Remington has done some good things technically the have made a difference.
The Versa Max and the V3 have been two fairly impressive semi-auto shotguns.
Remember the DPMS GII was designed by Remington's R&D group and is probably one of the better if not the best of the small frame 308 sized AR.
Remington made the ACR what it is today when Magpul couldn't. Yes Remington failed to support it properly but they took a cool concept from Magpul and made it a (nearly) viable platform. It certainly would not be were it is now by Magpul alone.
The RACS (Remington Accessory Chassis System) for both the PSR, CSR, and M2010 were way ahead of their time and for years where the bench mark against all other chassis guns were measured. You can still see the influences of those chassis on the current market of chassis guns.
How many new cartridges has Remington helped bring to the market in the past 20 years: 300 AAC Blackout, 450 Bushmaster, 30 RAR (even if they did not support it again but I like it), 6.8 SPC, no doubt others.
I have probably missed a few things but these are the ones I thought of off the top of my head.
