No products found.
The Xpress Threat Interdiction Sight (XTIs) is derived from its popular handgun tritium sights known for its super-fast target acquisition.
Works for the left-handed user simply by flipping the mount direction.
The sight adjustment is probably the worst out of all for a rifle platform, unlike others where you turn the dial with audible feedback. However, where this sight system shines the most is for quick target engagement within 21 feet or less.
However, the sight doesn’t align with the bore.
Other Recommended Offset Iron Sights
The Dueck Defense 45 degree rapid transition sight is similar to the SureFire offset sights, but they also make one for the left-handed shooters.
It’s an A-2 style sight, very easy to use for people who are experienced with the traditional M16 style sights.
No special tools required for adjusting the sights besides the front iron sight, for those who use PEQ15, the front sight is designed to clear beam path.
In addition, you can add fiber optics or night sights for the front sight post.
Compare this to the Ozark Armament, its a way higher quality pair of iron sights with Mil-Spec hard-anodized finish that seamlessly mounts onto any standard 1913 Picatinny rail.

Canted rapid transition offset iron sights give the shooter instant transition from magnified optic to fixed iron sights to engage close-range targets.

Just cant the rifle, and the sights are there.
Great for 3 gun and even home defense setup.
How to Zero Offset Iron Sights
Zeroing offset iron sights is the same as zeroing it as if they’re straight. You dial the elevation and windage until your point of aim is the point of impact, however, you have to make sure those sights are aligned to the bore of the barrel.
This goes the same for zeroing a red dot sight on an offset angled mount, which it has to align with the bore.
In the case that the iron sights don’t align with the bore, you will have a horizontal offset, which is not recommended.
Here is a great video guide on how to zero an iron sight, check it out.
Offset Iron Sights vs Flip Up Iron Sights
So why would you want an offset iron sights if you could just have regular flip-up iron sights?
Offset iron sights generally work very well for rifles with magnified optics. Regular flip-up sights are for red dot optic setup for co-witness.
Using the Aimpoint Micro along with a flip-up iron sights makes more sense than with a 4X ACOG.
Using an angled offset iron sights makes more sense with a variable power optic.
Left Handed Offset Backup Sights
For those left-handed users, the Strike Industries Sidewinder or the Dueck Defense offset iron sights can accommodate that need.
We really like the SI Sidewinder for its simplicity and price.
Zeroing Distance For Offset Iron Sights
The best zeroing distance for iron sights should be between 25 yards to 50 yards. The purpose of this setup is for close-range engagement and then switch back to magnified optic for long-range.
Other Offset Iron Sights Concerns
Most 45-degree iron sights are designed for top receiver rail close to the bore like the DI AR15.
For piston-driven rifles that have a high height over bore distance like the Sig MCX, SCAR, X95, the iron sights will not align with the bore, and your shots will be off.
The only way it’s going to work is if the angle is 30 to 35 degrees, or you can try mounting the front sight on the handguard side rail to see if they align.
However, even if this works out you might not have a place to mount the rear iron sight. In that case, it’s better to mount an offset red dot sight for these type of firearms.
