PTR-44 bullet button
Ever since Dianne Feinstein decided to launch her full scale assault on legal gun ownership, questions have come up to what extend we -as historic rifle collectors- will be affected by her proposals. It is now clear that it will all boil down to the magazine. If the magazine is considered detachable, and BTW, this will also be of concern if you own certain G43 models, the rifle may be classified and vilified as an "assault rifle" if it has at least one other feature as innocent as a muzzle nut (the "threaded barrel" part of Feinstein's proposal).
Past restrictions in California have led to the development of the bullet button. Relying on a tool for ejecting the magazine instead of simply pressing a release button -in this case using the tip of a bullet- makes the magazine a fixed magazine in the eye of the law (well, the LEOs may still see it differently but there's a flyer with guidelines issued by the Sacramento PD that every owner of an "assault rifle" should carry along with the rifle). Once the magazine is considered fixed, muzzle nuts and pistol grips become a non-issue.
Assuming that the whole nation will soon be as screwed up as California, I have decided to be pro-active and I've looked into developing a "fixed magazine" feature for the PTR-44. The first 2 pictures below show the piece parts of the original push button release, followed by my fixed magazine conversion. I decided not to use a bullet tip as means of releasing the magazine catch but to built a custom 2-prong tool in order to distinguish my contraption from the current AR-style bullet buttons with their known workarounds (magnetic button insert etc. <--felony!!!). In case our elected officials keep pushing us further against the wall by simply outlawing all detachable magazines, bullet button or not, I have already come up with with a solution making the magazine permanently attached (in lawmakers' lingo, "permanently attached" means you can't remove the magazine without first taking the action apart). Loading the non-detachable magazine will turn into a major PITA, though.
