How can wehelp?
Everything you need to know about CMI components, fitment, and how we run our shop.
Products & Materials
What materials do you machine your components from?
All CMI components are CNC-turned from titanium or 17-4 stainless steel. We do not use brass or aluminum in our arrow components — both materials are too soft to hold the tolerances and impact resistance our customers expect.
What's the difference between titanium and stainless inserts?
Titanium inserts are roughly 40% lighter than stainless at the same grain weight, allowing for FOC tuning without overloading the front of the arrow. Stainless inserts are denser, more affordable, and the right call when you want extra weight up front.
How tight are your machining tolerances?
We hold ±0.0005" on critical OD and thread features. Every batch is verified for weight, concentricity, and thread fit before it leaves the shop.
Fit & Compatibility
How do I know which insert fits my shaft?
Inserts are sized by the inner diameter (ID) of your arrow shaft, not the nominal name. See our Shaft Compatibility page for a full chart matching common shaft brands and models to the correct CMI insert size.
Do your field points and broadheads share threads?
Yes. All CMI field points and broadheads use the standard 8-32 archery thread, so they'll thread into any matching CMI insert or HIT system.
Warranty & Support
Are CMI components guaranteed?
Yes. Every component is guaranteed against defects in materials and workmanship. If something fails to spec, we'll replace it.
