WTS: Yankee Hill modular sight set (front sight + gas block + rear sight) off my Bushmaster. I have switch the sights out to better suit my needs but these always worked extremely well.
Front flip up straddles the low profile gas block. Rear is self explanatory. Gas block very low profile.
Asking $165.00
Please PM for pictures of the gas block and rear sight. They are too big to fit as attachments and I am too lazy to resize.
