More notes from phone conversation with RA 2000 to 2002. Finite Element Analysis was one of the tools used in during the design phase. Receivers were nitrided stainless with a service life of greater than 80,000 rounds. Six barrels were made in 6x45 cal. Fifty stainless heavy match barrels were slated for production, three had been produced at the time of that particular phone conversation. Unknown number of barrels were nitride finished. RECON carbines had chrome bores. RA was not in favor of this but did it anyway due to customer demand. 100 BREN kits were slated for production in two runs of 50 kits due to a part suppliers delay. The folding stock prototype was in testing. ( Later it would be carried over to the XCR ). The RAV-02 was select fire M96 derivative aimed for the MIL and LE market. It was chambered 5.56 feeding from AR mags and convertible to 7.62x39 feeding from AK mags. It featured a distinctly different lower that accepted standard AR grips and most M16 FCG components.
