AR15 Rifle and Pistol legalities

[saddlebum]

not sure if you guys are familiar with fixed mag, or bullet button.... want to make sure I can basically just dump those. The pistol may run into other issues too. as it has a shorter than 16" threaded barrel -- but it's a pistol so... as a fixed mag, legal in CA -- but may be an nfa issue if I take off the fixed mag? what about regular capacity?

here they can be as God and Eugene Stoner designed them. none of that silly commie California stuff here.
