Description
When you're running a magnified optic and need a quick way to engage up close, offset irons are the answer, and TROY has been doing them right for a long time. This set pairs an HK-style hooded front sight with a round rear aperture, mounted at a 45-degree angle so a slight tilt of the rifle brings them into view without touching your scope. The circle-in-circle sight picture is fast to pick up, and plenty of folks find the round aperture quicker on the eye than a traditional M4 setup.
What the TROY Offset Set Brings to Your Build
These sights fold compactly to either side of the rifle, and the ambidextrous base means lefties get the same clean deployment as righties, which is harder to find than you'd think in 45-degree sights. They sit at the same height as factory A2-style irons and fold down to just under a half inch, so they stay out of the way until you need them. The front post is adjustable for elevation, the rear handles windage, and both lock upright with a solid stainless steel cross-lock that keeps your zero put through recoil and hard use.
Getting the TROY 45-Degree Sights Dialed In
Installation is straightforward on any Mil-Spec Weaver or Picatinny rail, whether you tackle it yourself or hand it to your gunsmith. One thing worth knowing up front: these are built for same-plane rail systems, meaning your handguard rail needs to sit level with the receiver rail. They won't zero correctly on a railed gas block that sits higher or lower than the upper, so a continuous monolithic-style rail or a free-float tube that matches receiver height is the way to go.
Machined from 6061-T6 aircraft-grade aluminum with a hardcoat anodized black finish, this set has earned a reputation among tactical users and military folks for taking a beating and coming back for more. If you want backup irons that pair cleanly with a prism or LPVO and won't quit on you, these belong on the short list.

Frequently Asked Questions
Will the TROY 45-degree offset sights work with my magnified optic?
Yes, that's exactly what they're built for. Mounted at a 45-degree offset, they let you keep your scope or prism sight in place and simply tilt the rifle slightly to get on target up close. It's a clean solution for transitioning between magnified and close-quarters engagement without swapping anything.
Do these fit any AR-15?
They'll fit any AR-platform rifle or pistol with a Mil-Spec Weaver or Picatinny top rail on both the receiver and handguard. The key requirement is a same-plane rail setup, meaning the handguard rail sits level with the receiver rail. They also work on HK-style rifles with matching rail height.
Why won't the TROY offset set work with a railed gas block?
These sights are designed for same-plane rail systems, so they need the front and rear to mount at the same height to zero properly. A railed gas block that sits higher or lower than the receiver throws off that relationship and you won't get a reliable zero. Stick with a continuous or free-float rail that matches your receiver height.
Are these iron sights ambidextrous?
Yes, the base is fully ambidextrous, so the sights can fold to either side of the rifle. That's a real plus for left-handed shooters, since a lot of 45-degree offset sights only fold one direction. Righties benefit too, letting you set them up however suits your build.
