Highly recommended for xm-18!

These are better than the original bearings in my standard xm-18 3.5. The action and lock up is perfect now! I did have to grind down one bearing ever so slightly just to fit in the groove in the blade. I just used a fine ceramic stone and rotated the bearing a bunch to keep it as round as possible. It took 2 minutes tops. The other bearing didn’t require any modification. Still highly recommend!!

Skiff bearings are the Best bearings on the market!

Awesome bearings!!! Made my knife way way way smoother!!! I will be buying these for every knife I own for sure!!!

Hinderer Jurassic

I didn’t think the action on my Hinderer Jurassic could get any better but after I installed these bearings the drop action is more amazing. Hard to put this knife down now!!!

The only bearings I use

These are excellent. I have five sets total. Three hinderers, an SBD Evo Typhoon and a an apurvis primordial mk2. Couldn't recommend them more.

Put them in my xm-18 and wow, improved the action so much. Flips very good and falls shut.
