M16A2 Front Sight Post. Also known as an "A2" or "M4" Post (depending on which height)
This Post comes in two different sizes.
- Short Post - for most rifles
- Tall Post - for most Carbine and shorter barrels
If your Front Sight Post is too high or two low (within your Front Sight Base) once your gun is sighted in, changing the height of your Post can often correct your problem.
Order the Front Sight Post alone, or the full Assembly (Front Sight Post, Spring and Detent)
