WOW GK 4.9 Shipping NOW!!!

1412_A_IMG_1989_HDWe’ve started shipping the GK 4.9! This is a MAJOR evolution in the GK product line and is the most signifigant thing that we’ve done in years.
It takes all of the improvements of the 4.8 and builds on them.

this is by far the best filter that we’ve ever offered and if you are a RFL member or a GK4 owner we highly recommend that you join the RFL program and get yourself a GK4.9 filter!
