CA Legal 40 S&W Carbine

[edward]

There is/was and MP5/10 in 40 S&W, but it won't be cheap.

It will be about 2 grand... used... with 500 rds through it, and some internal mods for better extracting/ejecting.

That JRC sounds interesting and it isn't too pricey either. Thanks everyone for your suggestions.

Olympic makes a 40 upper. Very reliable.
