Eleven71 Design

Eleven71 Design manufactures precision red dot sight mounting plates from a single shop in Knoxville, Tennessee. The operation is a one-person, make-to-order business—plates are produced exclusively after orders arrive rather than manufactured in bulk and warehoused.

Optic plates for: - Glock - MOS, Gen6, Slimline MOS, 10mm/45 cal - Smith & Wesson M&P 2.0 - Multiple optic footprints - Sig Sauer - P320, M series, X-Five - Springfield Armory - Prodigy, XD-M Elite - Staccato - Standard and HD models - Beretta - APX, 80x/92/LTT - Walther PDP - H&K VP9 - CZ Pistols - MAC 1911 Double Stack - Custom fit optic plates for unlisted pistols

Plates also accommodate most common red dot optics: Trijicon RMR, SRO, 507C, Aimpoint Acro, Steiner MPS, Holosun EPS/509T, Vortex Defender, Leupold DPP, and Romeo X.

Most competition plates use aluminum or steel. Here's the physics: titanium experiences 2-3x less thermal expansion and thermal stress than aluminum or steel when the slide cycles. Every time you fire, heat cycles through the plate, screws, and optic. Aluminum expands significantly; steel creates greater internal stress. Titanium minimizes both. The result: fewer broken screws, better thread adhesion, and more reliable optic retention under repeated firing.

"Your optic is only as good as the mount beneath it... Your red dot optic mount should not be a block that joins the optic to the slide. It should look like it belongs there. It should blend the two pieces together."

Every detail gets attention: - Screws included - Torx-bits were broken during testing to ensure quality - Tight tolerances - Each plate is precision-machined for fit - Clean appearance - Plates integrate with the slide, not bolt on top - American materials - Sourced from US suppliers when possible

• •Anodizing - Surface treatment applied to titanium without changing dimensions. Adds protection; raw titanium is corrosion-resistant naturally.

• •DLC (Diamond-Like Carbon) - Applied via plasma-enhanced chemical vapor deposition. Coating penetrates the surface while maintaining tight tolerances.

• •Production: Make-to-order, typically ships within 1 business day once completed
• •Transit: 3–5 days via standard shipping
• •Warranty: No-questions-asked money-back guarantee if unmounted. Customer covers return shipping unless there's an error from Eleven71
• •Guarantee: Full backing on quality. If issues arise after mounting, they work with customers to make it right

Designed and refined by someone with a law enforcement background and years of competitive pistol shooting. The plates were developed after extensive testing and evaluation of red dot systems revealed critical weaknesses in existing designs. Built on the principle that product quality is visible before it's even mounted.

Eleven71 also produces handcrafted leather goods through Leather Provisions Atelier using Italian and American leather, all made in Tennessee.
