This is only the Advanced Reset Technology MP5-22 A.R.T. Lever w/ Buffer System, you will not receive the entire firearm.

Enhance the performance of your HK or Umarex MP5 .22LR with the Advanced Reset Technology MP5-22 A.R.T. Lever w/ Buffer System. This precision-engineered internal upgrade delivers active trigger reset assistance, allowing shooters to achieve faster, more consistent follow-up shots while preserving the platform’s reliable semi-automatic function.

Key Features

• Active Reset Lever Technology: Mechanically assists trigger reset using bolt movement for quicker release and pull cycles between shots.
• Adjustable Anti-Bounce Buffer System: Fine-tunes bolt timing to optimize performance across subsonic, standard, and high-velocity .22LR ammunition.
• Direct Factory Integration: Drops into the existing trigger pack with only minor fitment required—no proprietary housing or permanent modifications needed.
• Compact Design: Measures approximately 4 inches in length with a 2×2 inch profile and weighs just 8 ounces for seamless installation.

Benefits for Shooters

Traditional MP5-22 triggers rely solely on spring tension for reset, which can feel sluggish during rapid fire. The A.R.T. Lever addresses this by actively driving the trigger forward as the bolt cycles, promoting a positive and repeatable reset point. This results in improved control, reduced shooter fatigue, and enhanced accuracy during strings of fire—all while ensuring one round is discharged per trigger pull for full compliance with semi-automatic operation.
