Since the release of the SPEED VSR-10 Precision Sear Group (SA3099), SPEED Airsoft has now developed matching triggers, which are meant to be companion products to work with the SPEED Precision Sear Group in enhancing the performance of the VSR-10 much further.
The CNC milled SPEED VSR-10 Tuneable Triggers provide more precision over the stock cast versions by allowing the forward pull to be adjustable, so that you can achieve the shortest and crisp trigger pull every time.  The SPEED VSR-10 Tuneable Triggers have a new geometry milled into the sear surface to allow for a lighter and smoother trigger pull.  These tuneable triggers also use a precision ground pivot pin for a slop free operation.
