The SPEED Precision Sear Group includes a specialized first and second sear group that is designed to handle high spring power.  SPEED uses a set-screw for the second sear to ensure that during the pivot range, the second sear rotates true on the pivot pin with no shift or wobble.  The second sear contact surface is specially CNC profiled with a curve to minimize wear on the piston and extend the life of the piston to a greater amount of shots before replacement. 
Developed by SPEED Airsoft, the SPEED second sear utilizes a very special design of three precision ground pins that can withstand the most powerful spring that sniper owners would ever want to use in their VSR-10 sniper rifles.  The second sear pivots on the center pin and uses the other two pins as a sear lock up while the piston is cocked.  This feature allows the SPEED Precision Sear Group to function as a single sear once the piston is engaged. 
The SPEED first sear has been reinforced for added strength and the pivot pin is factory pressed in, to ensure that it pivots true and has zero play under load. The first sear surface is undercut so you can get a smooth and crisp trigger pull. 
The SPEED Precision Sear Group is machined from USA Grade billet aluminum and hard surface anodized for high durability.  It will fit the VSR-10 and other sniper rifles that are VSR-10 compatible.
