The issue with Remington is the Marlins suffering in poor quality after Freedom Group bought out Remington & Marlin, and subsequently Remington making the Marlins. Marlins' quality suffered a lot because they moved manufacturing to a different state. At the very least, the tooling & machining was not up to par. I heard the original manufacturing plant sabotaged the tooling & machine when they learned they were losing their jobs after Freedom Group bought them out. Who knows if it's true, but the quality of the Marlins definitely suffered when Remington started making them.
The Remington 700 rifles never suffered. They've retained high customer reviews. The ADL doesn't have the same quality finish as the BDL & CDL models, that's why it's less expensive, but it retains the same superior 700 action and, to my knowledge, barrels.
Remington even has great reviews on their 1911s, and RM380, and their RP series pistols.
They still make great shotguns, too.
