Rugged Suppressors OP003 Piston | M16x1 LH | 17-4 SS

The Rugged Suppressors OP003 piston is a purpose-built suppressor piston featuring a non-slotted, full-circumference gas seal designed to reduce gas blowback and improve the shooting experience on compatible hosts. It is machined from heat-treated 17-4 stainless steel and finished in copper for durability and corrosion resistance. This piston fits M16x1 LH threaded platforms and carries specific compatibility notes for certain hosts.

Applications include use on suppressor-equipped rifle platforms for range training and in precision or competition shooting where consistent gas sealing is desired. Note that this piston is not compatible with Kriss Vector firearm hosts, and fixed-barrel platforms require a spring replacement with a fixed-barrel spacer when using a piston.
