Xs Sightxti2 Dxw 45 Degree Offset Buis Big Dot Tritium Front / Non-Tritium
$174.99
The XS Sights XTi2 DXW 45-degree offset backup iron sights deliver a rugged, reliable aiming solution for AR-15 shooters who want redundancy without the bulk. Mounted at 45 degrees to your existing optics rail, these backup BUIS (backup iron sights) stay out of your scope's way while staying instantly accessible if your primary optic fails or gets damaged. Whether you're running a red dot, LPVo, or traditional scope, these sights give you confidence that you're never truly down to zero if something goes wrong downrange.
The standout feature here is the big dot sight picture—a large, differentiated white dot on the front post that pairs with a V-notch rear sight for a clean, fast sight alignment in any light. The tritium-powered front sight glows in low-light conditions without batteries, so you can acquire your target whether you're hunting at dawn or practicing after sunset. The non-tritium rear keeps costs reasonable while the rear sight's white outline aids in quick identification and proper alignment. For windage adjustment, the rear sight drifts easily for field zeroing, and the whole setup is fully ambidextrous—both front and rear can rotate for left-handed shooters.
Built from 6061 T6 aluminum bases and CNC-machined steel, these sights are tough enough for hard use and light enough not to slow down your rifle. Installation is straightforward: bolt them to your AR-15's top rail and you're done—no smithing required. Whether you're a competitive shooter, tactical trainer, or hunter who respects the firearm enough to have a backup plan, the XTi2 DXW offers peace of mind without compromise.

Frequently Asked Questions
Will these sights work on my AR-15 with a mounted optic?
Yes. The 45-degree offset design positions the sights to the side of your rifle rail, so they won't interfere with scopes, red dots, or other optics mounted on top. They serve as backup iron sights—a quick, reliable fallback if your primary sight fails or breaks.
Do I need a gunsmith to install these?
No. These sights use a simple bolt-on design for AR-15 top rails. Installation is straightforward and requires only basic tools.
What's included in the box?
The product ships as a set of front and rear sights—both can be installed on your rifle. The front sight features tritium glow; the rear sight is non-tritium with a white outline.
Can left-handed shooters use these sights?
Yes. Both the front and rear sights are fully ambidextrous and can be rotated to suit left-handed shooting positions.
How do I zero the windage on these sights?
The rear sight is driftable, allowing you to adjust windage by carefully moving it left or right on the rail. This lets you dial in your zero without needing to replace the sight.
