So bake is a magazine, is that a brand name or a type?
I’ve been through this recently - just got my first AK a few weeks ago.
Bake = Bakelite. This most commonly refers to Bakelite mags, but can also include Furniture. Bakelite is the earliest version of plastic from back in the 30’s and 40’s, consisting of layers of fabric/string/etc in a resin matrix.
Furniture = stocks, grips, handguards.
UF = Underfolder stock
SF = Sidefolder stock
Bake mags are desirable because they are lighter, thinner and slicker than steel and don’t have the sharp edges.
Drawback would be their price, and I imagine they don’t take the punishment a Magpul might. I have a magpul and it’s so-so. The Tapco poly mag I have is huge and ungainly. The steel mags I’ve got are heavy and sturdy, but you can dice a potato with the edges.
