Not what i was expecting - TruGlo AR-15 Tritium Front Sight

I ordered one of these beauties through my local gun shop expecting the TFO ar front sight post. Slightly disappointed to say the least. I took it anyway and i'm glad i did. the backup iron sight set i had swallowed this all the way to the detent collar. I then asked TruGlo themselves and they said that these were definitely compatible with mbus sights and could not guarantee compatibility with other sights. I recently picked up a Magpul mbus gen 2 front sight and the thing fit like a dream.now to buy the TFO and get a full set of Magpul mbus sights for my deer rifle.
