Breakthrough Clean Front Sight Adjustment Tool Features The Breakthrough Clean Technologies Front Sight Adjustment Tool is purpose built to adjust the front sight post on AR-15 rifles equipped with either A1 5-pin or A2 4-pin front sight assemblies. Covering both patterns in one tool means shooters do not need separate adjusters for different AR-15 configurations. The black oxide coated stainless steel construction resists corrosion and wear from repeated use at the bench or in the field. This coating also helps the tool hold up over years of range trips without rusting or degrading. A built-in handle gives a secure comfortable grip when rotating the sight post while integrated caps keep the tool protecting the sight during adjustment. The aluminum frame keeps overall weight down making it easy to carry in a cleaning kit or range bag alongside other maintenance tools. Finished in black and green for quick identification among other gear this tool is a straightforward addition for anyone maintaining or zeroing an AR-15 with iron sights. It is a practical dedicated solution for shooters who want accurate sight adjustments without improvising with household tools.
