We have a fit for every barrel!

AT3 is proud to carry adjustable gas blocks from Wojtek Weaponry, giving you an affordable upgrade to your rifle’s gas system. These gas blocks are fully adjustable, regulating the flow of your rifle’s gas impingement for improved reliability and longevity. Whether you’re adjusting a new AR pistol to prevent overgassing, or custom tuning a precision rifle’s action, these gas blocks will make all the difference in your new build.

These gas blocks also clamp onto the barrel, improving barrel harmonics and accuracy over gas blocks that use pressure directly on the barrel with pins or set screws. It is recommended to use a removable threadlocker – such as Blue Loctite – on the set screws that tighten the block around the barrel. Do not use threadlocker on the adjustment or locking screws.

FEATURES:

  • 4 sizes available: .625″, .750″, .825″, and .936 (.750″ is the most common size, but always measure the barrel if you aren’t sure!)
  • Low profile design, perfect for any free-float handguard
  • Steel construction (better than aluminum for withstanding extreme temperatures)
  • Secured using 3 set screws to clamp the gas block onto the barrel, increasing accuracy over pinned or set screw gas blocks
  • Gas tube roll pin included
  • Compatible with AR15 and AR10 platforms
  • Allen wrenches for attachment, adjustment, and locking set screws are optional but highly recommended. Sizes as follows:
    1. Adjustment screw = 5/64″
    2. Side locking screw = .05″
    3. Attachment screws= 3/32″

SPECIFICATIONS

  • Material: 1018 Steel, Black Nitride
  • Length: 1″
  • Height: Sits 3/8″ off of the barrel (fits under all free float handguards!)
  • Weight: 1.3-1.8oz depending on size
  • Packaging: PE Bag

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: These adjustable 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!

Too tall

Bought for my 450 bushmaster with an aero precision free floating Handguard, but the Handguard doesn’t fit over the gas block. The description says it’s a low profile design, but it doesn’t work for me. I doubt I can return it since it has been installed and removed, so I guess I’ll save it with the hope it will fit a future build.

Great, affordable adjustable gas blocks

This is the third time I've bought Wojtek clamp-on adjustable gas blocks. They are inexpensive for the quality they have, and they work great. I've got them on 308 and 300 AAC. They're effective and easy to adjust. Not sure why I would buy anything but these, to be honest.

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