CZ Mannlicher stocks do likewise. When I bought the 550 in 9.3 x 62 in 2002, I dawdled for about a month--weighing the Mannlicher/500mm barrel vs. Lux half-stock/600mm barrel question. I went for the latter, not knowing at the time about the CZ free-float/Mannlicher regimen. It has worked well for me. The several CZ rifles I have added since that purchase have all been half-stocks. I was VERY sorry to see the Mauser 98-system 550s go away, and the push-feed 557s take over. Following Winchester's 1964 example has EPIC FAIL written all over it. If it ain't broke--don't fix it.
