When purchasing AmeriGlo or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The AR Tritium front sight post from AmeriGlo brings the benefits of a self-illuminating night sight to your AR-15 rifle or carbine. The AR Tritium delivers a clear, crisp sight picture with a stand-out aiming point that really helps you locate your front sight quickly when operating in a low-light environment - especially in high-stress situations.

The AmeriGlo folks designed the AR Tritium to be a drop-in replacement for the standard A2 front sight post OR the post in a Magpul® MBUS® flip-up front sight. It provides the same range of elevation adjustment as your original post.

You can benefit from the AR Tritium’s enhanced sighting capability whether you’re working directly with your "iron, sights or co-witnessing them through a non-magnifying optic. That’s extra gravy on top of having an unfailing beacon up front on your rifle to guide you.
