It has been my experience with Euroarms, is that the lock parts are soft. They can be made to be VERY good shooters. as a side note I have a Garrett Arms miss rifle on consignment sale at Lodgewood Mfg, it has a Numrich bbl on it, and it is .58 cal. The bore is .577. It is Italian, made in the 80s. Has the 1855 md long rangge rear and a custom front site. It shot the RCBS N-SSA Minnie, with an over size base pin very well, with40 grns of 3F,and MCM (like SPG) lube.
