Troy's quality is spot on and and I do mean very well made! Nice mill work and a fine finish. I used this on a new build upper and there was no problem getting it on the barrel as I have had with other blocks. This made the build go extremely smooth!

Great product fit and looks perfectly satisfied with quality of product. I would recommend this gas block. Recently installed went on very easy fit nicely. I have not been able to take it out to the range yet.

Fit perfectly. Comes with set screws but does not come with roll pen (tension pen) for gas tube. (5/64 – .078) easy to install. Installed on dimpled barrel so I had no problem with alignment. Has Duell set screws.

Needed a .875 gas block for a 458 socom build. Turned to optics planet and Troy industries. Fit and finish were as I have come to expect, outstanding. OP got it here and the build was completed. I am gonna head to the range today for a test drive

Works great. The finish is a nice black that matched my barrel well. It fit nice over my 8.75 barrel not to tight. I did not drill pilot divits in the barrel for the set srews but i did put red loctite on them.
