In July of 2016, CA Governor Brown signed legislation that will mandate state registration of semi-auto centerfire rifles with certain "features". I won't register on principle, but will not violate the law either if the gun is modified so that it does need to be registered. "Modified" in the sense that it is no longer a semi-auto.
Turn the gas block on the barrel to block the gas port that routes gases to operate the bolt, and the gun no longer self ejects, cocks, and loads another round. Remove the gas tube or bolt gas key and it really can't be made into a semi without reinstalling a part.
There are available options that permit the shooter to pull straight back on a handle attached to the side of the bolt, the gun essentially becoming a bolt action rifle, but with only two actions, pull back to eject shell, and push forward (or let bolt return spring do it), to strip a round out of the mag and chamber.
Typically, to ensure reliable rapid loading and extracting of the case in a semi-auto, the chamber is on the loose side, avoiding potential hangups that may come with a tighter chamber. A loose chamber may not be be the best for accuracy. But if case extraction and loading are like a bolt action, could one not use a tighter chamber to hopefully enhance accuracy?
With a straight-pull action, other benefits are realized. Biggest one is a much cleaner bolt carrier assembly. No high pressure gas mixed in with bolt lubricants. Ugh! And of course, there would be no gas tube, no gas block, no gas key on the bolt, and no gas port drilled into barrel. There are other benefits as well.
In any event, without gas powered self ejection, loading, and cocking, the gun is not a semi-auto. No registration, a cleaner gun, and possibly more accurate if the chamber is cut more like a bolt action than a semi. I may try this. I have an AR-15 and AR-10 receiver, I may build as straight-pull actions, using a tighter chamber. What problems do you think I may run into? I would use 6.5 x 47 in the AR-10, but may want to see if it is possible to run a 6mmBR, which can be a challenge in any mag fed gun. Call me nuts, but I do like trying stuff like this.

I'm looking at a 93 acre farm in PA right now. Interested in renting
