    Just picked up a used USR rifle ... have a few questions about legalities

    can i add a take down button for the barrel? it seems like it might fit ... but 1 is it legal and 2 is it easy to do ?

    can i cut the barrel down and add a pinned down muzzle brake ? the law says no flash hiders , so would a muzzle brake be ok ? and if so , can i use one of those AAc's that would allow a suppressor to be attached?

    research seems to be not so much in favor of suppressing this rifle due to piston port noise .... anyone did it and can comment ?

    the 20/20 trigger sear seems to be the best part to improve the trigger... any recommendation ?

    thanks in advance!

    Are you talking about state laws?

    Yes you can add the quick release barrel button and it's legal in CA. I believe it was left off just to further differentiate the USR from the AUG for import. I put one on my USR and it works great. The grub screw in the USR has to be heated with a torch or heat gun until the thread lock compound release smoke. Then it can be removed and the new button installed.
    As far as your barrel, you could cut it down and thread it for a brake, but why not just order a new standard barrel and put the brake on that - it would be lighter weight. There are a few 18in barrels around (try PJS) and you could legally pin and weld a brake onto that and be legal in CA. I would just order the standard 20in threaded barrel and be able to change muzzle devices at will and be legal in either case.
