Wojtek Weaponry Arkto Click Adjustable AR-15 Gas Block
Wojtek Arkto Click Adjustable AR-15 Gas Blocks
The Wojtek Arkto adjustable gas block features a click adjustable gas setting for positive, repeatable results when adjusting your gas system. Unlike of the older style two-screw system, the Arkto resists carbon lockup with a ball-and-detent mechanism, plus NiPTFE coating on the screw. You get a full range of 24 settings with this gas block, ensuring that your rifle can be perfectly tuned.
Each gas block includes three allen wrenches for adjustments and installation, plus a 2ml vial of Vibra-tite. If you want to grab a gas tube at a discount, check out our package with Arkto gas block, AT3 gas tube and roll pins.
Will this fit under my free float handguard?
The Arkto fits great under most slim free-float handguards. The AT3 SPEAR M-LOK Rail and Quad Rail, the Aero ATLAS S-One and R-One, and many more will work great with the Arkto underneath. If you’re not sure, feel free to consult the diagrams for the gas blocks in the image gallery, or reach out to us. We’ll be happy to help you get exactly what your build needs.
How do I install this?
First, you’ll need to remove your standard gas block and tube from your rifle. Slide the Arkto onto your barrel, align the top witness hole with your barrel’s gas port. Then, secure the set screws to clamp the gas block in place. Wojtek Weaponry recommends using the included Vibra-tite on the screws, and going no further than hand tight.
After the threadlocker cures, secure your gas tube to the gas block with a roll pin. For more info on how to set up your gas block at the range, check out this guide to installing and tuning your gas block.
