Brand Name: LAMBUL
Model Number: MBUS PRO Front & Rear Sight Set
Function: Front & Rear
Came with Magpul markings, and in good working condition. However, those who are very familiar with Magpul MBUS PRO sights will recognize the adjustment knob is different, but to the untrained eye these will pass, and they do function as they should. If you're looking an acceptable knock off, they may just fit the bill. - From the U.S.A.
