A bit expensive for what it is but does the job perfectly. Ends play completely and provides tactile confirmation that rail is properly engaged.
As any MFT3 owners know there is a noticeable slop between the locator pin and the slot on the track. At least there was...thanks to Slop Stop it is completely gone. Yahoo!
While the price is steep for what you actually receive, getting rid of the slop makes it worth every penny.
Easy to install and great improvement.
Immediately on installation I could feel no play in the guiderail on my MFT. The play has driven me nuts causing me to doubt the accuracy of my MFT. I am looking forward to working with this in place.
