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 should be compatible with all the other handguards out there!

Exactly what I wanted

Item is exactly what I needed. I used this on my m&p ar15 sport so I could replace my hand guard. It functions as it should. I would recommend it.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Gas block

Gas block was great, the gas tube pin was not had to use a pin I already had to secure gas tube.

Thank you for the feedback, Roger. We're investigating these pins a little closer and considering a change.

Great product, quick delivery

I needed this gas block to complete my latest build. I removed the front iron sight, but I wanted to cover up the pin holes in the barrel. Shipping was faster than it I thought it would arrive. The description was perfect. Went right on the barrel and worked exactly as I had expected. Thanks!

Thank you for the feedback, Chris!

Exactly As Described

Gas block was exactly as described. My only issue was the 2 roll pins wouldn't fit into this gas block that came along with it. Had to use the factory one that was still reusable as much as I didn't want to. Roll pins that came along with the gas block seem to be a little too big to fit in or the gasblock itself needs be dimpled on both sides to reduce likely hood of mushrooming roll pins upon install. This minor issue won't steer me away from purchasing more parts AT3 though!
