I've been reading (and occasionally contributing) to this topic for some time now. I finally realized that a key point here is less about making a catchy statement than it is about attracting customers.
We (mostly) are not the customers, rifle builders are. The message they are seeking from the roll stamping (or whatever) that appears on the receiver is one that will help reassure their customers that what they are holding is a prime example of excellence.
QAA (Quality Assured Armaments); Assurance 700 (the flagship offering), Epitome 700, Pinnacle 700, Top Gun 700, etc. make for a good start on the model name hunt.
AAA ( 'triple A') Assured (Assurance?) Armaments Actions, and names starting with 'A' are usually at the top of most lists, and multiple 'A's are at the top of the 'A' List....); similar model names, etc.
QED (Quality Engineering and Development, or quod erat demonstrandum, meaning "which had to be demonstrated". ); same-same.
QfQ (Quality from Quality); self explanatory.
If the name doesn't sell itself to both of the customers (the builder and the shooter), it's not helping.
Also, when a company name includes words like 'Quality' and 'Assurance', it has to meet a higher standard. Buyers will be expecting this, and will know that all involved will have to meet it. Public advertising would do well to acknowledge this, and such acknowledgement can go some ways to bolster the action makers customers' (the builders') reputations. Delivering each action to the builder with a gentle written admonition that the action maker's reputation depends on the builder's diligence as well can help this admonition come true for both parties. They could even pass that written admonition on to the shooter as a sign of their own diligence.
For example "Our customers are building quality from quality, providing the American Shooter with a rifle that does the Constitution and Second Amendment proud. Look for the AAA (or QED, etc.) on the action". Make it a policy that wherever the Company name appears, it is always followed by the phrase "Quality from Quality, crafted with respect for both the Customer and the Second Amendment. Your actions are all we build, and everything we build.".
