I have noticed this for months but never really thought about writing an article about it until today. I have been sent several emails and have read in the forums about folks not needing to cut the forestock to install my HP Barrel Band. On previous Gauntlet models, it was required that the forestock be trimmed about 13mm or so to allow the band to fit on the tank without pressing against the forestock.
At some point in production, Umarex decided to use another regulator manufacturer other than Ninja. I noticed these non Ninja regulators on the, at the time new, .25 caliber Gauntlets.
I noticed then that they were about 13mm or so longer than the Ninja versions.
This new regulator being longer means there really is not a need to trim the forestock on the Gauntlet in order to fit the HP Barrel Band. As you can see in the photos, the non-Ninja regulator is much longer.
I have no idea how you would be able to determine if you will receive the Ninja version or the new one other than when you open the box and see for the first time.
So for any of you potential HP Barrel Band installers out there, if you have the newer regulator, your installation just became a whole lot simpler and most importantly to the average shooter, the warranty stays intact!
Lastly, even though these regulator styles are different, it has been my experience that they both accept the same shims. I have noticed the new version regulators are more sensitive to shim thickness than the Ninja regulators. IE; it seems to take less shim to achieve the same amount of increase. But the important thing is my shim kit will work in either.
Work and shoot safe!
