what solutions available for CA compliant Sig MPX or Kriss Vector?

i've been searching for a AR Maglock type product that works for my MPX. I reached out here to figure out if one exists so I can use it instead of going featureless. If not...I'll register.

The regular AR bullet button will fit the MPX. It leaves an ugly-as-sin hole above and below the bullet button, but it will fit. Two years ago I PPT'ed an MPX with a regular AR BB. An MPX Raddlock now sits there.

If you do choose to go featureless, this is the best solution available IMHO.

Cool. A raddlock sits in mine now and I had to punch the roll pin out on the left side to get rid of the ambi mag release function. Now im debating if I want to run the Patriot release that people linked above...but time is running out!

Time is running out, but not. You can always separate the upper from the lower and finalize things later if need be.

Or just use a standard AR magazine catch.

I registered mine as mine is a pistol. I can keep it in NV but I want options ..

Regarding the Kriss, I'm happy to report that the Viper modular fixed stock, which I just installed today, fits the Kriss Vector II very nicely, and is super easy to install. Its FDE version even matches the Kriss FDE rather well. This, along with a grip wrap (which are all ugly) makes the Kriss featureless.

At least, that's the way I understand it.

Viper is located in Santa Ana, Calif., so shipping anywhere in Calif. is pretty quick.
