I can attest to the very well thought out design of for forti-cinis striker system. I used the system in a Project Guns Bren that was giving me some trouble. It has cleared up and cleaned up the operation of that semi auto design. It is the best solution for the semi auto conversion of a Bren gun.

To those in the UKicon. A good number of design changes have to be made to a reman'd full auto as our ATF (Alcohol, Tobacco and Firearms), as I still call them, has to approve said designs in order to not be in violation of Federal Law, or "making machine guns". They tend to vary between makers, but the denial pin set up means there are two protruding pins inside the receiver to keep a full auto or unmodified Bren bolt from going home. Each gun has slightly different "denial" features. But they all (except for one ill fated hammer design) have to be a striker system. No Open Bolt guns any more here, unless they are full auto or a grandfathered design like some of the early open bolt semi auto MAC-10 copies.

It IS a complicated collection of laws and restrictions.
