One downside of the AR-15/M4 platform is the incompatibility with rail systems that extend past the gas block. However, Spike's Tactical provides a solution with their Micro Low-Profile Gas Block.

This gas block is reduced in size so that you can install any rail system you want. It is machined out of solid billet steel, and every surface is given a tough melonite coating. Retention is provided by two set screws as opposed to the clamp design of other blocks. The tight tolerances ensure that gas will not leak out and impact your rifle's reliability.

Give your gas system an upgrade and expand your rail system options with this high-quality gas block from Spike's Tactical.

    The gas block I received is good quality and installed easily onto my rifle. The reason this review gets two stars is that no set screws were included with the gas block, even though the package says they are included. Whatever is specified to be included with a product should be included and not require the buyer to spend extra money for parts they need. *** Wing Tactical Comment *** Hi, thank you for your feedback. I am sorry to hear that the set screws were missing. Please contact us at We are more than happy to take care of this.
