Geissele Automatics - Carbon Steel Gas Block

Customer Reviews

This is a .750 gas block

Review by Stephen

I don't have the heart to down vote this good block because of incomplete documentation and my own carelessness. It's a nice block that will match your other "G" branded products. The outside is a decent cast surface and the bore is nicely machined completely smooth. Unfortunately, it's a .750 block and I need a .625. I should have asked before I bought. I'm a little surprised that this critical piece of info is missing from its description.

Carbon Steel is Darker Than Picture

Review by Ryan

I love the gas block and I'm completely satisfied with it; however, the SGB I received is black and not a brushed silver like in the picture, not an issue just a warning for those expecting the same finish in the product's picture. Super easy to install, great instructions, and it's a Geissele product.

Solid Install - Great Instructions

Review by Patrick

I selected this block to fit under my ALG EMR V1. The block is well built and cleanly machined. I did the optional pinning on top of the set screws and I have total faith the block will stay put. What I found especially remarkable was the instructions. Very detailed, left no questions unanswered. The instructions even go so far as to include McMasterCarr part numbers so a user can get the exact right drills. This is my go-to gas block.
