Let’s Talk About Precision Reflex Pri Low Profile Gas Block .750 Diameter
The Precision Reflex Pri Low Profile Gas Block .750 Diameter is a seemingly simple, yet incredibly vital component in the AR-15 platform. This unassuming block of steel plays a crucial role in directing gas from the barrel to the gas tube, cycling the action, and enabling semi-automatic fire. Precision Reflex, known for their quality AR components, offers this low-profile gas block as a reliable solution for those seeking to build or upgrade their AR-15.
I found myself needing this particular gas block when undertaking a custom AR build. I wanted a free-floating handguard that would extend past the gas block, requiring a low-profile design.
Upon unboxing, I immediately noted the robust construction and clean finish. The magnesium phosphate coating gives it a durable, no-nonsense appearance. My initial thought was that it seemed like a well-machined and solid piece.
Compared to other gas blocks I’ve used, like the Yankee Hill Machine Low Profile Gas Block and the generic gas blocks often included in budget build kits, the PRI offering instilled more confidence. The PRI felt more precisely machined and the finish appeared more durable than the others, justifying the slightly higher price point. I picked the Precision Reflex due to its reputation and the positive reviews I read online, seeking a reliable, no-frills option that would perform consistently.
I was initially excited. The build quality suggested that it would be a reliable component in my new AR-15.
