Sounds good, but how does it perform?
How Does It Work?
The handstop part of it is pretty straightforward.
While many polymer handguards have integral handstops built-in, most can be fairly small.
When you grip it, the pressure activates a green laser that is built into the handstop.
The battery will run for an hour and a half continuously before it will need to be replaced.
The HS1 is built for M-Lok attachment points.
If you have an M-Lok handguard, it may be an easy switch to an HS1.
TheSAINT Victor rifleand theSAINT Edge rifleboth have M-Lok free-float aluminum forends.
TheSAINT riflehas BCM PMCR or B5 Systems handguards.
While these have M-Lok compatible attachment points, they also have an integrated handstop.
Built-in handstops may pose a slight problem.
The SAINT I had in for this review hasB5 Systems furniture.
The handguard is made of polymer.
It too, has M-Lok attachment points, but it has an integrated handstop.
Theres a quick fix, though, if youre handy.
A belt sander, or even a soldering iron (to melt a hole through) will work.
But let me be clear here this is my idea, and not Springfield Armorys or Viridians.
And guns and tools both demand caution and care.
Be safe with both.
As the video at the top of the page shows, I used a Foredom grinder.
Ive got a decent shop and had a double-cut file bit that made short work of it.
A drill would work fine if you brace the forend well.
Also, a Dremel is an option.
In the End?
Based on my range time with it, the HS1 lives up to its promise of rapid target acquisition.
At close range, the bright green dot is easy to see.
you could move the rifle freely and watch the dot move, too.
It is intuitive, fast, and adds an extra level of control.
All in all, I think its a very nice addition.
