JP JP-5/MP5 Lock Piece
JP JP-5/MP5 Lock Piece
JP-5 Lock Piece functions as the tuning element of the roller-delayed JP-5 system, similar to how an adjustable gas block serves the AR platform. This interchangeable component allows shooters to optimize recoil impulse and cycling characteristics for different ammunition, barrel lengths, or configurations. Each JP-5 Lock Piece is precision-machined from proprietary steel and finished with a lubricious nitride coating to ensure minimal wear, low friction, and long service life.
