Wojtek Click Adjustable AR-15 Gas Block with Gas Tube and Roll Pin
Outfit your AR-15 with an overhauled gas system, with the new Wojtek Weaponry Arkto gas block, AT3 gas tube with roll pins, and all the tools you’ll need to install. The Arkto gas block features 24 gas settings with positive clicks for adjustment, and a NiPTFE finish to resist carbon lockup. Just choose the gas block diameter and gas tube length you need, and you’ll have the perfect package to upgrade your AR-15.
No matter what package you choose, it will include the following:
- Wojtek Arkto Gas Block
- AT3 Stainless Steel Gas Tube
- 2 AT3 Gas Tube Roll Pins
- Allen Wrenches for adjustment and installation
- 2ml vial of Vibra-tite
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.
