Stalker™ Series

Loaded with every technology available for AeroInsert-A, AeroInsert-H and AeroPoint, the Stalker Series takes advantage of every patented insert technology we’ve created so far and reapplies them for the 0.166” ID size shaft. Turning the traditional insert on its literal head, our AeroStem system allows for field changes from field point to broadhead. This series meets the challenge of the harsh environment of global competitions head on.

The Stem System: AeroStem™

Target archers who use 0.166" class shafts and prefer not to use outserts have few alternatives past glue-in points. This is unfortunate because when a field point eventually becomes bent or damaged, the arrow becomes unusable. While others try to avoid that damage through the use of more durable tungsten points, their price at $200 to upwards of $400 per dozen makes this an impractical alternative. At Firenock we have taken a entirely different approach, one we call the “stem system” aka the Stalker Series. Together, the Stalker AeroInserts (SIA/H) and interchangeable Stalker AeroPoints (STP) as well as Stalker AeroStem SwingBlade (SBST) broadheads mate seamlessly with a 0.166” class shaft (AeroWeave166 shown).

Two AeroInsert Versions

The Stalker Series includes two insert versions: the Stalker AeroInsert-A (SIA) and The Stalker AeroInsert-H (SIH). Together, they utilize up to three patents. Every insert is equipped with our reverse tapered shoulder for durability as well as our patent-pending dual O-ring for perfect concentricity. The addition of our patented double shoulder on our SIHs allow for use with AeroConcept tubes. Installation with a CTI160 will result in a shaft with greatly reduced oscillation ( i.e. less energy waste) as well as a stronger frontal end.

For those who love the simplicity of our AeroSystem components, our SIAs are great upgrades. Including the aforementioned technologies, the Stalker inserts, even at their small size, are hollow for a light weight and easy Firenock lighted nock system installation. Their hollow shape is only made possible due to a new EDM drilling process, making a 0.5mm hole through the entire insert. Finally, for those for a quick transition into hunting season, our two-part system allows for replacement with most broadheads.

New for 2020: The Stalker SwingBlade Points & Broadheads

Soon after the early 2020 release of the Stalker Series AeroInserts and AeroPoints comes the broadhead version for fall: Stalker SwingBlade. Equipped with the interchangeability that both its parent series boast, the Stalker SwingBlade includes two all new AeroStem bodies that mate perfectly with the current Stalker AeroInserts as well as the SwingBlade head and blades (only Falcon, Talon, and Saber shown) for use on 0.166” ID size shafts. Easily replace these bodies with Stalker AeroPoints for practice.


Currently offered components are built to fit 0.166" ID class shafts. Examples of popular arrows with a 0.166" ID include the Firenock AeroWeave166, the Black Eagle Deep Impact or X-Impact, the Carbon-Express Maxima SD, the Element Storm, and the Easton Injexion. Firenock Stalker AeroInserts and Stalker AeroPoints are made with 420 hardened stainless steel and all have an outer diameter of about 7mm. In terms of weight, our Stalker AeroInsert are 38gn (SIH) and 50gn (SIA) respectively while the AeroPoints come in seven weight sizes: 35, 45, 55, 65, 75, 85, and 100 grains. While the Stalker SwingBlade bodies have the same OD at 7mm, the 75gn body is made of 7075 hard-anodized Aluninum while the 115gn body is machined from 303 Stainless Steel.
