Scalarworks PEAK/Fixed Iron Sights Larry Vickers

"After using their optic mounts, I approached Scalarworks about making a set of fixed iron sights; what they came up with has exceeded my expectations. I'm now running Scalarworks iron sights and Aimpoint Micro mounts on my BCM carbine in all of my training classes. Scalarworks Leap Mounts and Peak Sights are the current state of the art."

From Peep to Post

In making the Peak Sights we left no stone unturned and few parts untouched.

Scalarworks PEAK/Fixed Iron Sights CNC machined

Every major component is custom designed with meaningful improvements to function, and precision CNC machined to the highest standards of fit & finish.

Right Radius

Peak Sights are designed around a modern 15" sight radius. While carbine length rifles have become the norm, most fixed iron sights still use components designed for the M16A2's 20" sight radius.

Scalarworks PEAK/Fixed Iron Sights adjustment

Peak Sights have manually adjustable elevation (front) and windage (rear): Both with a refined 0.5MOA/click, which matches most Red Dot sights'.

Scalarworks PEAK/Fixed Iron Sights post

The Peak sight post is CNC machined to the correct width for a 15" sight radius, non-rotating for finer adjustment, and flat faced to eliminate highlight bias.

Corrective Vision

The human eye intuitively centers objects within a bright aperture.

Scalarworks PEAK/Fixed Iron Sights peep

Peak Sights have precision CNC milled apertures that are flat toward the shooter, so they won't create highlight bias.

Scalarworks PEAK/Fixed Iron Sights peep

Stock A2 peep apertures are cast and have a scallop facing the shooter that can generate a misleading highlight.

    Like others have said before, these sights are of impeccable quality and exquisite construction. The sight picture is excellent and is an example of irons done right. However, I have one chief complaint – the front sight lacks adequate range of adjustment. Although designed for 5.56mm carbine applications, I mounted mine on an 8″ 9mm MPX and co-witnessed them with a red dot optic. Unfortunately, there is not enough adjustment range in the front sight and it bottomed out before achieving zero. I am a few hairs’ breadth shy of zero at 25m. This was highly disappointing, especially at the high price point. My options are to return them or take a file to the exquisite front sight. Either are painful decisions. Because of the prevalence of pistol caliber carbines, for which these sights may be employed, I recommend improving the range of adjustment in the front sight. The result will be a much more versatile piece of kit.

    These sights are fantastic. I have several front sights I’ve paired with KAC 600 meter rear sight and they work great with that thinned front sight post. I also have a set of these(front and rear) and it’s actually enjoyable to use irons again.

    I’m not a high speed guy, so take this with a grain of salt, but this is a really excellent rear sight. I like irons, because reasons, and prefer this to my mbus or ruger (oem) rear. It fits my zen, and it looks hawt af on my flattop with A2 front sight.

    Wildly brilliant construction. I would like to ask if I could exchange the rear for a LEAP 1 standalone mount.
    Great construction, smooth & milled perfect. Congrats!
