NEW HDD P90 SILENCER, MADE FOR THE FN P90 & PS90 SBR CARBINES. THESE HAVE A MONOCORE BAFFLE SYSTEM FOR EASY CLEANING AND IS A DIRECT THREAD 1/2X28 SILENCER. MEASURES 7.5" LONG BY 1.5" DIAMETER AND WEIGHS UNDER 12 OZ. THESE ARE DESIGNED FOR THE P90 CARBINE WITH A EXPANSION CHAMBER AND ONE PIECE MONOCORE BAFFLE THAT HAS 8 CHAMBERS. VERY QUIET, LIGHT WEIGHT AND OVERCOMES THE BURST CASE SCENARIO IN THE P90 CARBINES. A HEAVY STEEL SILENCER WITH A LOT OF BACK PRESSURE CAN CAUSE A BURST CASE PROBLEM DUE TO RESTRICTING FREE MOVEMENT OF THE P90 FLOATING BARREL DESIGN. THE BARREL TRAVELS REARWARD EVERY SHOT WHICH DELAYS THE UNLOCKING OF THE BOLT AND CHAMBER BUT HEAVY SILENCERS RESTRICT THIS MOVEMENT CAUSING EARLY UNLOCKING OF BOLT AND CHAMBER LEADING TO A BURST CASE SCENARIO. A BURST CASE IN A P90 CAUSES THE MAGAZINE TO BLOW OUT OF THE WEAPON AND INJURIES TO THE OPERATOR CAN RESULT.  THERE IS NO BURST CASE SCENARIO WITH A HDD P90 PURPOSE BUILT SILENCER. THESE ARE T6 ALUMINUM, HARDCOAT ANODIZED MATTE BLACK, DISASSEMBLE FOR CLEANING AND HAVE A STEEL INSERT WITH THE 1/2X28 THREADS FOR LONG LIFE.   BURST FIRE RATED.

A SILENCER IS A NFA ITEM SO MUST TRANSFER TO YOUR LOCAL CLASS 3 FFL DEALER ON A FORM 3.
