SIK Golf Pro C-Series Armlock Putter

Blade Putter

SIK Golf built its reputation on one idea: loft at impact matters more than almost anything else in putting. The 2021 Pro C-Series Armlock takes that idea and pairs it with the most stable putting method allowed under the rules. This is the style of putter Bryson DeChambeau made famous, and SIK was the company behind his. The armlock setup presses the grip against your lead forearm, which takes your wrists almost completely out of the stroke.

The Pro is SIK's blade, milled and clean, with no alignment aid to speak of. That last part is a choice, not an oversight. SIK's position is that a well-fit armlock putter squares itself through setup and geometry, so the topline stays uncluttered. You aim it like a blade because it is one.

Be clear about what you're signing up for. Armlock putting requires a different setup, a longer build, more loft, and a real adjustment period. Golfers who commit to it tend not to go back. Golfers who dabble usually do.

Design

The face is where SIK separates itself. Descending Loft Technology mills four distinct lofts into the face, decreasing from top to bottom, so the ball launches consistently whether you deliver the putter with more or less shaft lean. That matters twice as much in an armlock, because the whole method is built on a pronounced forward press. The armlock version carries significantly more static loft than a standard putter for exactly that reason, so the ball still comes off the face with proper launch instead of getting driven into the ground. The head itself is a milled blade with mid toe hang. That hang point is worth noting, since many armlock putters go face balanced. Mid toe hang gives the putter some natural flow for players whose stroke keeps a slight arc even with the forearm anchor. Combined with the longer shaft and oversized grip typical of armlock builds, the total package is heavy, stable, and deliberate.

Who It's For

• Players with shaky or handsy strokes who want the wrists locked out of putting entirely.
• Golfers who putt with a slight arc and prefer a blade shape, since the mid toe hang works with that motion rather than fighting it.
• Anyone willing to commit to a real transition period, because armlock putting is a method change, not an equipment tweak.

Frequently Asked Questions

Is the armlock putting style legal?

Yes. The rules ban anchoring the club to your body, but bracing the grip against your lead forearm is explicitly allowed because the forearm counts as part of your gripping arms. Armlock putters have been used on the PGA Tour for years without issue.

Why does the SIK Pro Armlock have so much loft?

The armlock method has your hands well ahead of the ball at address and impact, which delofts the face. SIK builds extra static loft into the armlock version so that after the forward press, the effective loft at impact lands in the normal range. Their DLT face then handles the remaining variation with its four descending lofts.

Does mid toe hang make sense for an armlock putter?

It's less common, since the armlock method reduces face rotation and many armlock models go face balanced. But plenty of players retain a slight arc even with the forearm brace. If that's you, the mid toe hang on the Pro C-Series lets the face release naturally instead of feeling like it's resisting your stroke.

How is the Pro C-Series Armlock aimed without an alignment aid?

You aim it off the topline and the leading edge, the same way you'd aim a classic blade. The armlock setup itself helps here, because the locked-in forward press makes your setup extremely repeatable. If you rely heavily on a sightline to aim, this putter will ask you to adjust.

What length and grip do I need for an armlock putter?

Armlock putters typically run 40 to 42 inches so the grip can extend up your lead forearm, and they use a long, often oversized grip designed for the brace. Your fit depends on your height and how high on the forearm you anchor, so getting the length right matters more here than with a conventional putter.
