Richard, unfortunately buds won't modify a firearm to make it state compliant and they won't ship it to a FFL/gunshop for them to modify it. Sorry but hope this helps.

Richard, unfortunately Bud's does not do compliance work, nor will they ship to a FFL for compliance work. The rifle must be CA compliant as is, or Bud's will not ship it. Sorry but this is Bud's policy. You can find a CA compliant MPR model here, which has been fitted with a fixed magazine or MagLock, making it compliant >>> https://wbtguns.com/rifles/ruger-ar-556-mpr-california-legal-450-bushmaster/

Sorry to say, Bud's will not do any compliance changes to any firearm. And, as mentioned, they will not ship said firearm to an FFL in a state where that firearm is not compliant for that FFL to make compliant.

Hi Richard, unfortunately Buds does not alter any firearms for compliance other than shipping without non-compliant magazines. It would help many folks out, but it is not a service that Buds offers. Cheers and stay safe!
