On 2003 FABARM introduced a new gas system, the PULSE PISTON (PATENDED) which was considered as a revolution. No more valve like competitors shotguns, but a piston with a soft polymer insert to regulate the reloading...with an incredible recoil reduction.
PISTON PULSE WITH THE IMPROVED AND PERFECTLY RELIABLE NEW ACTION BAR. THIS ACTION BAR IS USED ON ALL FABARM SEMI-AUTO FROM JUJY 2005 AND IS INTERCHANGEABLE WITH THE PREVIOUS ACTION BAR PROFILE. PLEASE CONTACT YOUR DEALER FOR ALL INFORMATION.

All the pressure is used to reload the shotgun
WITH HEAVY LOAD SHOTSHELLS
