*Add a PEEK striker to your order by clicking on “choose an option”.
PEEK striker:  For all calibers – Marauder pistols, Woods Walker Pistols, 17xx  series pistols. 

Allows for installation using a 1/8″ hex wrench – just like the factory striker.

+ No more metal ping sound when the hammer strikes the valve stem.
+ Lightweight;  Removes about 5 grams from the total hammer weight for a higher shot count.
+ Keeps the valve stem from mushrooming at the tip – where the striker impacts.  This allows for easy and safe removal of the valve stem, without damaging the valve body.


New Item   Spacing shims for your hill airgun PEEK striker.  The hill airgun PEEK striker is designed for a flush fit to the hammer. When performing the o-ring buffer modification, you may find that you may or may not need to space out the striker some. Includes 2- .005 thick shims and 1- .020 thick shim. Use no shim, 1 shim, 2 shims, or up to 3 shims, to achieve  the perfect tune. *Buffer mod o-rings are listed in the o-ring section.

Add a hill airgun lightweight Pistol hammer kit, to your order.

Some of the Features Include:

+  Precision CNC machined from a solid piece of hard and durable 7075 aluminum, then anodized blue.
+  No missed shots like with non metal hammers, since the hill hammer does not change shape – distort, drag, or hang up inside the reservoir tube, with temperature or humidity changes.
+  The hammer operates smoothly and quietly during the rifles shot cycle.
+  Already drilled and tapped and a set screw is installed, to prevent the striker from moving.
+  The hammers hard surface allows for a crisp trigger break
+  Ventilated for faster and more consistent hammer movement.
+  Less valve dwell for more shots per fill and quieter shooting airgun.
+  Great for regulated applications.
+  Weighs less than the stock hammer. Only 20 grams  (25 grams with the factory striker installed).
