Breakthrough Clean Pivot Lock Features The Breakthrough Clean Pivot Lock secures the AR-15 s upper and lower receiver in the open position at the takedown pin holding the action locked open throughout a cleaning session. This keeps the barrel and chamber fully accessible without needing to hold the receiver open by hand freeing both hands for scrubbing the bore or wiping down the bolt carrier group. Because the action stays fixed in place there is no risk of the receiver swinging closed and pinching fingers or interrupting a cleaning pass mid-stroke. The lock is sized specifically for the AR-15 platform so it installs quickly without any tools. This pivot lock pairs naturally with other cleaning accessories such as a bore guide or lower vise block forming a complete stable cleaning setup for a thorough maintenance session. Regular cleaning is essential to reliable AR-15 function and a pivot lock makes that process noticeably easier and safer to perform especially for solo cleaning sessions without a helper to hold the action open. Its compact size makes it easy to keep in a range bag or cleaning kit for use wherever maintenance is needed. This is a small inexpensive tool that meaningfully improves the cleaning experience.
