JP Enterprises JP-5 Lock Piece - 70Adeg 70Adeg Roller Bearing Angle A Competition Recoil Reduction A Proprietary Steel A Nitride Finish A JP-5 / MP5 Pattern A SKU: JP5-LP70 The JP Enterprises JP-5 70Adeg Lock Piece is the preferred competition angle for shooters optimizing for recoil reduction on the JP-5 roller-delayed platform. Proprietary steel with nitride coating for low wear and low friction. The 70Adeg angle runs any standard pressure loads reliably but operates closer to the edge of the functional window with very low-pressure loads such as 130 or 150 Federal Syntech or similar light hand loads. More frequent cleaning is recommended when running the 70Adeg with low-pressure loads. Compatible with H&K MP5 and MP5 clones that accept H&K lock pieces. Validate bolt gap after installation. 70Adeg - Competition Recoil Reduction The 70Adeg lock piece requires more force to open the action than the standard 80Adeg-reduces felt recoil for competition use. Runs standard pressure loads reliably. Operates closer to the functional edge with very low-pressure loads-more frequent cleaning recommended in that configuration. Proprietary Steel with Nitride Finish Manufactured from proprietary steel with nitride coating for low wear and low friction throughout the service life of the component. MP5 Platform Compatibility Compatible with JP-5 and H&K MP5. Compatible with MP5 clones that accept H&K lock pieces-not all MP5 clones are compatible. Validate bolt gap after installation as lock piece geometry may alter bolt gap.
