Probably the RRAs will be at best carried / stored a lot and shot little. . In a "good year" I will shoot a issued rifle 300 rnds. I'll clean and/ or lube it more times than shoot it. I shot my muzzle loader at a range more than my duty rifle.
As said most LEOs and Mil. are not in the "know" on firearms and for the most part are not liked or shunned. I would not be surprised if a "fud" shooter has more trigger time at clods and cans than average special agents duty rifle, not a knock on them just not the main focus of their job.
The lowest bidder/ best connected (kickback ? ) wins bids in a lot of cases. . M9 pistol comes to mind (Mil. Bases in Italy?)
