Bull Craft PKM / M60 Hop Up Unit 2.0

Bull Craft PKM / M60 Hop Up Unit – Revision 2.0

When reliability fails, we build what’s missing. After countless service cycles on PKM and M60 platforms, we found the available hop ups lacking—fragile, inconsistent, and not up to Bull Craft standards. So we engineered our own.

⚙️ Precision Grip, Tactical Control
Borrowing from our proven Stoner 63 design, the adjustment wheel delivers aggressive grip and micro-tuning precision—dial your BBs in with confidence, even under field stress.

🔩 Durable Fit, Zero Slop
The C-Clip locks in tight. No wobble. No compromise. This unit is built to take abuse and hold zero.

🚀 Now Shipping: Revision 2.0
This is our latest evolution—stronger, smarter, and field-tested. If you run a PKM or M60, this isn’t an upgrade. It’s a necessity.
