Tune Your Gas, Master Your AR

The patented Superlative Arms gas block puts you in control of your AR’s gas system for unrivaled flexibility and performance. Our innovative design bleeds off excess gas pressure rather than restricting flow, preventing fouling buildup on critical components. This exclusive mode optimizes cycling while reducing recoil for faster follow-up shots.

Machined from solid steel and finished in nitride for exceptional durability, the Superlative Arms block is set-screw adjustable in bleed-off or restrictive configuration. Tune your rifle dynamically based on ammunition type, environmental conditions, and shooting use from long-range precision to high-volume CQB. With an adjustable Superlative Arms block, no AR is out of your reach. Take your AR performance to the next level with the adjustable gas block innovator – Superlative Arms.

  • Patented Bleed Off gas regulation technology

SA adjustable Gas Block

I had initially ordered a different brand of gas block from a different company. I subsequently saw the SA Adjustable from AT3 Tactical, cancelled my first order then bought the SA block. What I love about this gas block is it’s adjustability in bypass mode. I attempted to shoot my suppressed 6.5 Creedmoor with a standard low profile gas block and experienced less than stellar results. After some reading on shooting suppressed rifles it became obvious that I needed an adjustable gas block.
My rifle barrel is bead blasted stainless. The stainless gas block from AT3 looks beautiful on the SS barrel as it is just exposed at the end of tubular fore grip. Adjustability is fantastic. I spent roughly five rounds getting the block dialed in to eject the shells at the three o’clock position per the very detailed instructions and associated pictorial graphic.
I am very pleased with the appearance and functionality of this gas block; a very worthwhile purchase.

Over gassed rifle fix

My AR 15 was over gassed. It was ejecting the casing at 2 o’clock and I had to hold my breath when I shot it due to blow back. I installed the Superlative Arms Adjustable Gas Block, made 6 click turns and now it’s flawless! I highly recommend this product for any gassing issues (with your rifle) of course!!

Nice adjustability

I have around 200 rounds through a 20" barrle with this gas block and was able to dial it in pretty quickly (4 rounds). I notice the recoil is lighter (not that you feel a lot with a 20" barrel anyway)
But! I did notice the bcg ran cooler and wasn't as carboned up as before using a milspec gas block. I intend to move it over to my pistol build when I'm ready for it.

Thank you for your review! We're glad to hear that our Superlative Arms gas block provided easy adjustability and improved performance for your barrel. We appreciate your feedback and are happy to hear that you plan on using it for your future builds. Happy shooting!
