Tacfire rifle gas block - Tacfire Rifle Gas Block

This product is a good value. It is a true low profile gas block. Some gas blocks claim to be low profile, only to find out they will not fit under certain quad rail or other forearms. I use these on just about every build requiring a low profile gas block. The only con I have is the gas tube pins are usually not the right size. They seem too big. I've had to go with a different pin almost every time.
