wow what can i say about these... THEE best $23 i have ever spent! easy to install on the vfc/dboy/echo 1 MK17. the stock selectors were sloppy, These are nice crisp clean a satisfying click in each mode. the selectors not only look awesome but preform extremely well. Im not one for the magpul horde but magpul makes really good products that work! i was leary about buying these thinking "are they really worth $23, will they fix the sloppy stock selector?" yes they did. buy these you wont regret it and you will be thinking damn i should have bought these earlier.
nice tactical look
great build quality
improves selector engagement
price may deter some but i can see zero cons with this item
