Frequently asked questions: 
Q: How can I tell what size of gas block I need?
A: The gas block size is based on the outside diameter of your barrel. The most common size is .75″ (this is the military standard). If you aren’t sure – use calipers to measure  the diameter of the barrel, in the area where the gas block sits. Or alternatively, you can try looking up the make and model of your rifle online for more details.
Q: How do I know if this gas block will fit under my handguard?
A: Our micro gas blocks are as small as you will find on the market. They are guaranteed to work with our AT3 handguards, and they are compatible with all the other handguards out there!
Q: How do I know what size of gas tube I need?
A: Measure the distance from the barrel shoulder to the gas port on your barrel and compare to the list below. (Carbine is the most common length).
Distance to port:
Pistol = 4 inches
Carbine = 7 inches
Mid = 9 inches
Rifle = 12 inches
