Barrel Testing Taken To Another Level
We’ve seen a lot of barrel tests over the years, but this one left us speechless. The level of detail and methodology in this review is absolutely incredible. From using a micrometer to check gas block journal tolerances, to measuring component’s torque specs, to mounting a Mantis X10 Elite to grade shot stability – this isn’t just a test, it’s a master class in firearm evaluation.
The 30-shot groups tell a story that 3-shot or even 5-shot groups simply can’t. Shooting consecutive shots over four minutes with a chamber chiller between groups gives us real-world data about how our barrels perform when they heat up.
That’s the kind of information that matters when you’re actually running the gun hard.
What really blew us away was the introduction of the A-Zone Equivalence Distance (AZ score). Converting group sizes into practical, real-world applications like USPSA A-zone hits at distance? That’s genius. It takes abstract MOA numbers and turns them into something every shooter can understand.
We’re obviously thrilled that our Precision SPR Barrel dominated the test, but we’re even more impressed by the testing itself. This is the kind of thorough, unbiased, scientifically-minded evaluation that pushes the entire industry forward. When someone spends their own money on the barrel, ammo, and testing equipment to create content this detailed – that’s something special.
This is what happens when you combine engineering mindset with practical shooting experience. We couldn’t have asked for a more thorough or professional evaluation of our barrel.
