Tangent Theta, SAI Optics, and Tenebraex Discounts for Silvercore Club Members

If you have been researching Tangent Theta scopes, you already know the numbers. A Tangent Theta is not an impulse buy. It is a decision you make once, and then you live with it for the next thirty years.

A Silvercore Club membership is $59 CAD per year. A 10% discount on a single Tangent Theta pays for the Club membership many times over, with change left for a tank of fuel to get to the range. If you are buying SAI Optics or Tenebraex, the math is even better.

That is the headline. Here is the rest of it.

What Silvercore Club members get from Armament Technology

Armament Technology Incorporated (ATI) is the Halifax-based Canadian company behind all three of these brands. They manufacture Tangent Theta in Canada, they own and designed the SAI Optics line, and they are the manufacturer of Tenebraex scope covers and anti-reflection devices.

Silvercore Club members get a standing discount on all three:

Tangent Theta

10% off for Silvercore Club members. Prices on armament.com start at $4,753 USD for the 3-15x50mm Long Range Hunter and go up to $6,592 USD for the 7-35x56mm. Join the Silvercore Club or log in to access your discount code.

SAI Optics

15% off for Silvercore Club members. The SAI 6 LPVO is $1,335 USD. Accessories start at $96.99 USD. Join the Silvercore Club or log in to access your discount code.

Tenebraex

20% off for Silvercore Club members. Scope covers start at $55.69 USD, with accessories fit for most major scope brands. Join the Silvercore Club or log in to access your discount code.

Prices shown on armament.com default to USD. Canadian pricing is available by switching the country selector on their site to Canada. Your discount code will be issued through your Silvercore Club member account.

The math, for the people who want the math

Let's use a Tangent Theta 5-25x56mm Professional as the reference. Current price on armament.com starts at $6,091 USD. A 10% Silvercore Club discount is over $600 USD off, about $835 in Canadian dollars at today's exchange rate.

The Silvercore Club membership costs $59 CAD per year.

For someone who has never bought a Tier 1 scope before, the discount alone is worth more than the membership fee by an order of magnitude. And that is before you factor in everything else a Silvercore Club membership includes.

Put the 15% SAI Optics or 20% Tenebraex discount into the same math and the result is the same: the membership pays for itself on the first order and keeps paying for itself every year you renew.

Why these three product lines are worth the discount in the first place

I have written at length about what I saw inside ATI's Halifax facility. The Class 100 clean room, the machines that drop every scope 1,000 times at 1,000 g, the pressure chambers that simulate submersion, the temperature testing from -55 to +85 C, the turrets they have tested to over 30,000 revolutions. If you want the full story, read The World's Best High-End Rifle Scope and listen to Silvercore Podcast Episode 90: The Rolls Royce of Rifle Scopes.

Here is the short version:

Tangent Theta is built in Halifax by people who own their own testing equipment because no off-the-shelf equipment is rigorous enough for what they want to prove. Failures are rare enough that when warranty work is needed, there is a good chance the person repairing the scope is the same person who originally assembled it.

SAI Optics is ATI's own brand, designed and specified by the same team behind Tangent Theta. Same design philosophy, same attention to detail, at a price point that sits in the upper-mid rather than the top tier. If you want Tangent Theta thinking without the Tangent Theta price tag, SAI is where you look. The SAI 6 is a first focal plane 1-6x24 LPVO with ATI's proprietary Rapid Aiming Feature reticle, backed by SAI's Limited Lifetime Warranty.

Tenebraex is the accessory line ATI manufactures in Halifax: scope covers, anti-reflection devices, polarizers, sunguards. The flip caps actually flip, they lock open when you want them open, and they do not vibrate loose under recoil. For anyone shooting a centre-fire hunting rifle in the rain, a proper Tenebraex cover is not optional. Tenebraex also makes accessories fit for Vortex, Leupold, Trijicon, Nightforce, Sig Sauer, and most other major scope brands, so the 20% discount applies even if your glass is not ATI.

What else you get with a Silvercore Club membership

The Tangent Theta, SAI, and Tenebraex discounts are three benefits on a list of more than twenty. A full list of current member partner discounts is available on the Silvercore Club page.

Beyond the partner discounts, a Silvercore Club membership includes:

  • $5 million CAD of third-party liability insurance covering hunting and shooting activities across North America
  • RCMP-approved ATT eligibility. The Silvercore Club was the first gun club in Canada to receive official RCMP approval for issuance of Authorizations to Transport
  • 100% off Silvercore's online courses (excluding Online CORE, Waterfowl 101, and Anchored Outdoors branded courses)
  • Member-only Live Q&A events with industry experts
  • Outpost, a private podcast feed available exclusively to Silvercore Club members
  • Canada-wide and international membership. The Club serves members in every province and territory, and internationally

All of that is $59 CAD per year.

How to claim the Armament Technology discount

  1. Become a Silvercore Club member (or log in if you already are) at silvercore.ca/club.
  2. Check your member account for the current Armament Technology discount codes.
  3. Shop at armament.com and add what you want to your cart.
  4. Apply your code at checkout, and have your Silvercore Club membership letter available. ATI may ask for proof of active membership.

Discounts apply at the time of purchase. They are not retroactive.

The takeaway

If you are in the market for a Tier 1 scope, or even an upper-tier scope, the honest answer is that you should join the Silvercore Club before you put anything in your cart at Armament Technology. The discount more than covers the membership the first time you use it, and you pick up a few million dollars of liability insurance, a stack of other partner discounts, and ATT eligibility on the way through.
