SIK Pro C-Series Armlock Putter

The SIK Pro C-Series Armlock is the armlock variant of SIK's 2021 Pro C-Series, itself a follow-on to a line witbhub.com reports first launched in 2020. What sets the C-Series apart is the face, described by witbhub.com as four flat planar surfaces milled into the putter face with loft decreasing by 1 degree from top to bottom, from 4° to 1°, a treatment SIK calls Descending Loft Technology. The armlock designation refers to one of several hosel configurations witbhub.com lists for the model, alongside plumber's neck and slant neck, paired here with a length range the same source puts at 38 to 43.5 inches and a loft of 7 degrees.

Pricing on this release is disputed between sources: witbhub.com reports an MSRP of $749.99, while pgatour.com lists it at $499. Both are outlet figures, not a maker-confirmed number, and the gap is worth noting rather than resolving. Elsewhere the record is more consistent, with witbhub.com describing a clean blade profile with rounded corners and a contrasting black sightline, an oversized grip set with its wide flat side parallel to the face, and an upright lie.

The putter's standing on tour is the most repeated thread in the record. Both witbhub.com and pgatour.com tie the model to Bryson DeChambeau, with witbhub.com and pgatour.com both crediting a DeChambeau win at the 2020 U.S. Open to this model, and witbhub.com further noting the putter is currently used by 2 professional golfers across the PGA Tour, LIV Golf, DP World Tour, and LPGA Tour. Community sentiment on witbhub.com goes further, calling it one of the most notable putters on tour, a claim that reflects that visibility rather than any verified count.
