The New Innerloc 6 Pack 4 Blade 125 gr Fixed Blade Broadheads are built for hunters who want proven fixed blade strength, dependable accuracy, and serious cutting performance. Featuring four .020″ blades and a 1 3/16″ cutting diameter, these 125 grain broadheads deliver a strong cutting profile in a durable, field-ready design.
At the core of this broadhead is Innerloc’s patented Center Locking System™, also known as CLS Technology. This system is engineered to lock the tip, blades, and ferrule together with exceptional strength. When the tip is tightened, the matching bevels at the top of the ferrule and inside the tip create a clamping action that forces the components together so tightly they perform much like a solid piece of metal.
The blades are designed with an L-shaped profile for unmatched strength. The base of each blade is curved to sit perfectly against the round shaft of the tip, creating metal-to-metal contact from top to bottom. This secure blade fit helps improve durability, alignment, and energy transfer on impact.
The heart of the Center Locking System™ is the tip itself. By extending the tip through the length of the broadhead body, Innerloc is able to thread the tip into the base, which is the strongest area of the broadhead. This design helps transfer a powerful amount of arrow energy at impact, giving hunters a fixed blade broadhead built for confidence when the shot matters.
Sold as a 6 pack, these 4 blade 125 grain fixed blade broadheads are a strong choice for hunters who want reliable Innerloc construction, secure blade retention, and proven CLS performance.

#1: The matching bevels at the top of the ferrule and inside the edge of the tip create a “clamping” action when the tip is tightened. The tip, blades and ferrule are forced together so tightly they perform much like solid metal.
#2: The blades (gold areas show how parts mate when assembled) are “L”-shaped for unmatched strength and the base of the “L” is curved to lay perfectly against the round shaft of the tip. Metal to metal contact top to bottom!
#3: The heart of the Center Locking System™ is the Tip. By extending it throughout the length of the broadhead body, Innerloc can thread the tip into the base.This is the strongest area of the entire broadhead and securing the tip at this point transfers a walloping amount of arrow energy on impact!


“Sharp Beyond” All Innerloc® fixed blade broadheads feature Endur-Edge™. A special manufacturing and tempering process on the highest quality stainless steels that yields an ultra durable blade edge. This keeps the broadhead sharp as it passes through it’s target, causing better blood trails. Everyone knows the importance of sharp broadhead blades. But a sharp blade that won’t hold it’s edge is no more effective then a dull blade. Endur-Edge™ blades stay keen after they punch through hair and hide to slice the vitals effortlessly causing the immense blood trails and quick bleed-outs that Innerloc® is famous for.

Slide the triangle shape of the supplied wrench over the point of the tip. Carefully loosen the tip.

The tip can now be turned counter clockwise to disengage the threads.

Slide the tip out of the front of the body. Note the way the blades wrap around to create room for the tip to slide in and out.

One at a time slide the blades out of the front of the body. See the way the blades “L” shaped flange is located within the hole of the body.

You can now install new sharp blades by following the steps above in reverse order.
” IMPORTANT TIP” With Innerlocs’® front loading design and Center Locking System™ you can change the blades without removing the broadhead body from the arrow. This means you won’t de-tune the broadhead to arrow union assuring continued accurate flight with the new blades.
