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!

Was a little bit weary with some of the reviews. Ordered the extra pins just in case. Didn't need them so will use on another build. Great product. Fits nicely. Way better than the clamp on blocked that I have destroyed by over tightening and stripping out

Originally, this part was not in stock. After an email, they were able to get this part to me and it fits where I needed it to.

After removing the front site from an AR, I was left with the scars. The long gas block was the perfect length to cover the problem. Looks good too.

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.

Was just what I needed to cover A2 scars

Bought this to replace a cut down A2 gas block sight post. Fit's under my 1.300 ID rail on my lightweight build. The A2 block would have fit under a 1.500 ID rail, but I wanted something thinner. Also it's made of 4150 steel and the other ones I found were 4140 or didn't say what they were made of.

AT3 Tactical · Thanks for sharing your feedback, John. We're glad you're satisfied with your purchase. Cheers!
