A booth was giving away free samples of a new cleaning product intended to be an alternative to bore patches.
From an initial glance it looks like a Q-tip (likely from where the name Bore-tips is derived). Rather than cotton they use a mesh foam. The representative said they can be washed & reused several times.
While I am not sure if these will be economical compared to traditional patches. If they prove effective, the time saved would likely justify their added cost.
$5 for 6 Bore-tips includes free shipping. Depending how many times of re-use they last Bore-tips could prove to be a minimal cost over patches.
NOTE: I notice these are made in Springfield, Mass. I wonder if these were somehow born out of the S&W factory. Perhaps An employee who came up with an easier way to clean the test guns.
