I have a magpul BUIS and a troy BUIS, In all honesty I wish I would have went magpul on both rifles. If I was using a front sight on a gas block I would be using troy other wise its pretty hard to beat the magpul sights , they sit low when closed , simple lever to open up and just push them down to close, The Troy I have to flip up with is no big deal but you have to push the slide in to close it , again no big deal . both very well made .
Just watch out for the china made PTS airsoft replicas , buy from a reputable dealer
