Rack Gear Upgrade Kit :

This item is a combination of rubber stops, washers & bolts.  

 If your serial number is between 2300 and 10475, then this will improve the feel of the Boss and ensure long life of the Gear Rack and AR-10 gear.

It installs in 5 minutes. Watch the video to see it done step by step.
