The Burris XTR Signature Scope Rings 1 Inch 1.00in Height (420231) are a two-ring set for 1 Inch scope tubes, sitting at a 1.00in (25.4 mm) optical centreline on any Picatinny or Weaver rail.
What sets the XTR Signature range apart is the Pos-Align insert system. Each set ships with one concentric 0 MOA set, one ±5 MOA set, one ±10 MOA set and two ±20 MOA sets, letting you build 0, 5, 10, 15, 20, 25, 30 or 40 MOA of cant without touching your windage or elevation turrets — so you keep your full internal adjustment range for shooting rather than spending it correcting the rail. The polymer inserts also grip the tube without marking it, and correct off-centre receiver holes, which removes the need to lap the rings or fit a tapered base.
How It Compares
Same rings, different height: Burris XTR Signature 1-inch scope rings, 1.25in height (420232) and Burris XTR Signature 1-inch scope rings, 1.50in height (420233). Same system, different tube size: Burris XTR Signature 30mm scope rings, 1.00in height and Burris XTR Signature 34mm scope rings, 1.00in height. Browse all rifle scope rings, the full Burris scope mount and ring range, or the wider Burris optics range.
Ideal For
- Deer stalking and hill rifles where the receiver holes or rail sit slightly off centre and you would otherwise have to lap the rings
- Rimfire and .22 LR target rifles on a Picatinny or Weaver rail, where a marked tube on a resale scope is worth avoiding
- Long-range and gallery rifle work needing extra elevation without buying a tapered base
- Any 1-inch scope you would rather not mark — the Pos-Align inserts grip without biting into the finish
- Pairing with a 1-inch deer stalking scope that needs its full elevation travel kept for dialling

UK Delivery & Support
UK-stocked and dispatched tracked from our UK warehouse — no import duties or customs delays. Backed by UK-based aftersales support and the Burris Signature Warranty (formerly the Forever Warranty; the name changed in December 2025, the lifetime cover did not).

Frequently Asked Questions
What do the Pos-Align inserts on the Burris XTR Signature rings actually do?
They let you angle the scope inside the rings. Combining the supplied sets — one concentric 0 MOA set, one ±5 MOA set, one ±10 MOA set and two ±20 MOA sets — gives 0, 5, 10, 15, 20, 25, 30 or 40 MOA of cant, so you gain elevation for long range without spending your turret travel and without buying a tapered base.
Do I need to lap the Burris XTR Signature rings?
No. The self-centering clamps and polymer Pos-Align inserts align the scope and take up receiver-hole misalignment, so lapping is not required. The inserts also hold the tube without marking the finish.
What height are the Burris XTR Signature 1-inch 1.00in rings (420231)?
1.00in (25.4 mm) measured from the rail to the centre of the scope tube. Burris does not give this set a height name — use the centreline figure, as retailer names for these rings are inconsistent.
What scope tube diameter do the Burris XTR Signature 420231 rings fit?
They fit scopes with a 1-inch main tube only. Burris makes the XTR Signature range in 1 Inch, 30mm and 34mm, and the ring bore is not adjustable between them.
What torque should I use on the Burris XTR Signature rings?
Burris specifies 20 in-lb (2.3 Nm) on the ring top screws and 45 in-lb (5.1 Nm) on the cross-bolts, tightening alternately in an even pattern.
