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

Very nice looking gas block that adjusts easily. My 18 inch 7.62x39 build seems to function perfectly although I’ve only fired 40 rounds to date.

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

Wojtek blocks work

I haven’t purchased this from AT3, just found this site and saw them sold here. However, I have bought a few Wojtek AGB’s and am very satisfied with them. It’s a good product and the man behind them is an outstanding guy with great customer service and communication. All that being said, I don’t recommend these gas blocks for something that you’re constantly going to be adjusting, like if you’re regularly taking a whisper pickle on and off your AR and need to frequently regulate the amount of backpressure. For those applications I recommend a Superlative or SLR for the ease of making adjustments. However, where the Wojtek blocks shine are on applications where you want to tune the gun for proper function and/or recoil reduction, where once you get it dialed in it’ll stay that way and adjusting 2 screws requiring two different hex keys isn’t a big deal. The most recent one I bought was as a gift for my neighbor who got his only AR (S&W M&P Sport II) and was disappointed by the amount of recoil in comparison to my rifles. I didn’t believe the recoil in his M&P could be as bad as he said it was...until I shot it. And he didn’t believe my claims that an AGB would fix it. However, we needed to replace the factory FSB/gas block anyway to install a free-floating handguard I gave him, so we gave it a shot. It drastically reduced the recoil in his overgassed Smith & Wesson and made a lifelong AK-guy grow to love the benefit of a softer-shooting platform that allows him to make faster follow-up shots, and now it’s the rifle that he takes to the range with us the most often.

On both his rifle and my rifle, once I had the adjustment finalized I used a tiny dab of locktite ONLY on the set screw on the side of the block and haven’t had any issues.

Pics aren’t of his rifle, but of mine. The one with the gray furniture has a .625 Wojtek AGB on a Faxon 14.5” Gunner barrel with mid-length gas system under a V-Seven Lithium-Aluminum alloy (2099 I think...) l...
