QR2 Pool Cue Extensions

The Predator QR2 Extension adds length to your cue's butt with a single turn of the handle, so you can reach shots that would otherwise call for a mechanical bridge. It pairs with any Predator cue equipped with the Uni-Loc Weight Cartridge System, as well as Poison cues.

What Does a Pool Cue Extension Do?

A cue extension screws onto the butt end of your cue, adding a few inches of length so you can comfortably reach shots that would otherwise require a mechanical bridge. It's most useful when a ball sits near the rail on the opposite side of the table from your position, or in tighter rooms where a full bridge isn't practical. It's not a permanent cue modification — most players screw it on only for the specific shot that needs it, then remove it.

What Sizes Are QR2 Extensions Available In?

The Predator QR2 Extension comes in three lengths: a 3" Mini for players who want just a little extra reach without changing the cue's balance much, an 8" length that suits most rail-side shots and is the most popular option, and a 12" length for the longest cross-table shots.

Will a QR2 Extension Fit My Cue?

The QR2 Extension pairs with any Predator cue equipped with the Uni-Loc Weight Cartridge System, including Sneaky Pete SP4, SP6, and SP8 Series; 8K and 9K Series cues; BK3 and BK-Rush break cues; Blak 2nd, 3rd, and 4th Generation Series; and Predator CRM and Molinari by Predator carom cues. It also pairs with Poison cues — see our QR2 Poison compatibility guide for one fit note worth knowing on certain Poison models.

How Do I Install a QR2 Extension?

Installing a QR2 Extension takes three steps: remove your cue's existing rubber bumper, install the Uni-Loc QR2 Extension bumper using a standard 6mm Allen wrench, and twist on the QR2 Extension handle — a single turn locks it in place. The extension ships with the bumper already attached, so most players only need to complete this process once. For a full walkthrough with video, see our bumper installation guide.

Where Is the Bumper on My QR2 Extension, and How Do I Install It?

Predator QR2 extensions ship with the bumper already screwed onto the extension, arriving together in a protective sleeve.

  • To remove the bumper: Grip the black threaded section and unscrew it counterclockwise to detach it from the extension shaft. Once removed, you'll see the stainless steel bullet pin underneath — this is normal and is what the bumper threads onto.
  • To reinstall: Line up the bumper threads with the bullet pin and screw clockwise until snug. Watch the video below for the full walkthrough.

Can I Use the Same Bumper Across Different Extension Lengths?

No — the bumper bore differs by extension length, so a 3" extension's bumper won't interchange with an 8" or 12" extension. If you want to switch between lengths for different shots, you'll need a bumper matched to each extension you own.

Can I Buy Replacement Bumpers for My Predator Cue?

Yes — replacement bumpers are available for most Predator cue lines, matched to your specific model. Find your cue.
