Most Helpful Positive Review Nice, solid gas block
I got this specifically because of the approximately .420 screw hold spacing for a Daniel Defense 10.3 barrel. The DD barrels come pre-dimpled from the factory, and this one does match up almost exactly based on my calipers. It appears to have a nitride finish, and the inside in machined well. Mine did not include a gas tube roll pin, so that's a drawback. The set screws are also flat face, they are not knurled. However, if you're planning to pin it, that won't be a problem It is absolutely small enough to fit within a 1.3 - 1.5" ID rail.

Great Gas Block

by Matt, Verified Owner from VT, United States Written on April 10, 2024
If you’re not getting an adjustable block this is the way to go. Great fit and an overall solid block. Have always liked Spikes tactical products.

Micro gas block

by CK, Verified Owner from AR, United States Written on March 20, 2024
This is a good-looking gas block, but it won’t work on my current build. The .625 build I started needs a barrel, but the one I ordered is no longer available. I’ll probably keep it to complete it later. Will up dat my review if I get to use it. Might just send it back.

Love All Things Spikes Tactical

by Gladiator077, Verified Owner from TX, United States Written on February 26, 2021
Replacing A2 front sight on my AR-15 to add a new handguard and needed a low profile gas block. Of course it works like it's supposed to. Went with Spikes Tactical on this gas block because it's Spikes Tactical.

Great little gas block (but bring your own screws)

by RobvH, Verified Owner from FL, United States Written on December 28, 2018
This is a quality, well machined gas block. Fit on my DD S2W barrel is precise and easily fits under my floating guard. Uncharacteristic of Spikes, this doesn’t include the needed set screws. I say uncharacteristic because in their lower parts kits they include extra detente in case you lose one.
Pros:
  • Small fit
Cons:
  • Missing screws
Best Used for:
  • Floating rails
