Instructions: Jag Brush TM for Rods

It is easy to use a Jag BrushTM. Simply trap a patch against the barrel using a Jag BrushTM. Grab the brush with one hand, and use that hand to insert and guide the brush-patch combo into the bore while using the other hand to apply moderate force behind the rod. After pushing patch through the barrel, pull it off, or leave it stuck to the bristles for the return trip of the stroke.

Any jag, a standard one or our Jag BrushTM, works best when used with our Triangle Patches TM. But the Jag BrushTM may be used with square or round patches.

Do not use a square patch larger than recommended, or else the brush's core may bend. Below are maximum dimensions.

Jag BrushTM Caliber --> Max Square Patch (inches)
17 --> 0.75 x 0.75
20 --> 1.0 x 1.0
22/223/5.56 --> 1.25 x 1.25
243/6 --> 1.25 x 1.25
25/6.5 --> 1.5 x 1.5
270/7 --> 1.75 x 1.75
30/308/7.62 --> 2.0 x 2.0
32/8 --> 2.25 x 2.25
338 --> 2.25 x 2.25

Use Like a Standard Jag

If you do not want the patch to stay on during the return trip of a stroke, then remove the patch after the combo exits the bore at the end of the forward trip.

Single Purpose

When a patch is not applied to the front section of the brush, the Jag BrushTM acts as a typical single-purpose bore brush.


Because our Jag BrushTM is long, a patch extremity aka corner cannot reach over its connector base. Many standard solid jags or loops are not long, and at caliber 30 and below, the clearance between jag base and bore wall is less than a thick-cotton flannel patch thickness. When a patch reaches there, the combo of patch with standard jag or loop is likely to become stuck in a bore. See details in press release here.


Our Jag BrushTM bristles are less massive than solid jags or loops, and that results in no damaging high friction. A solid jag being heavier than our Jag BrushTM creates 10,000 to 36,000 times more mass friction and 90 times more pressure friction. See details in press release here.
