Anything I've ordered they have fulfilled my order quickly and promptly! Excellent service
Excellent gas block
This gas block is nicely finished in melonite. The set screws work perfectly and secure, especially if you dimple your barrel. Fast shipping and excellent communication when you have a question.
Compact and made of steel
This little gas block fit perfect inside of my new free float hand guard, the only reason I didn't give 5 stars is it does not come with any sort of paperwork or instructions. Luckily it is easy to find detailed instructions on-line.
Seems to work good (will not be testing to see if it can handle the heat better than the last one)
