Description
Product Overview
Sig Sauer SISOSBDX63111 is the SIERRA6 BDX-R2 riflescope with a 3-18x44mm optical range and a 30mm main tube, packaged as a quantity of 2 (SKU: SISOSBDX63111). The product is listed under Optic > Scopes and is identified as a digital ballistic scope with a second focal plane (SFP) reticle.
Why This Product
- Digital Ballistic Scope (BDX) — the scope is specified as a Digital Ballistic Scope (source_fact_id: product-267941:f009), which indicates it is part of Sig Sauer’s BDX-enabled optics line and may integrate with ballistic tools in that system.
- Second Focal Plane (SFP) — the reticle is SFP (source_fact_id: product-267941:f010), meaning magnification changes do not alter reticle subtensions; useful for holdover marks that remain constant at one reference magnification.
- 30mm Tube and 3-18x44mm Range — model name and sizing (SIERRA6 3-18×44 30MM BDX-R2) identify the magnification band and tube diameter, which are primary mounting and optical spec references (source_fact_ids: product-267941:f001, product-267941:f013).

Appropriate Use Cases
- Procurement for retail assortments needing BDX-capable scopes: stock the 3-18×44 SIERRA6 BDX-R2 in multiples (pack qty 2) to supply customers wanting digital ballistic optics (source_fact_ids: product-267941:f009, product-267941:f008).
- Installations where a fixed reticle scale is preferred: use the SFP scope when buyers require reticle subtensions that do not change with magnification (source_fact_id: product-267941:f010).
What Customers Should Know
- Verify mount and clearance for a 30mm tube and the 3-18x magnification band to ensure proper eye relief and ring selection; tube diameter and magnification are given in the model identifier (source_fact_id: product-267941:f001).
- Package includes two units—confirm order quantities and inventory planning reflect the pack quantity of 2 (source_fact_ids: product-267941:f008, product-267941:f011).
- The scope is identified as a Digital Ballistic Scope (BDX); confirm integration or compatibility requirements with any external ballistic or rangefinding systems before purchase (source_fact_id: product-267941:f009).
