Any opinions out there on steel vs. aluminum, vises that require lead inserts, etc.?
Gunthings has a vise at a good price (about $83 at the present) that can be used on various barrels (see:
FNFAL & L1A1 Accesssories, Tools, Videos).
Or, would anyone recommend Brownell's vise system, which has interchangeable inserts, both steel and aluminum (quite a bit more costly, though).
