The Cadex Defense X-Serie Bridge is a precision optic mounting platform engineered specifically to fit the Remington 700 short action footprint. Machined from aircraft-grade 6061-T6 aluminum, it delivers a rigid, full-length top rail that maintains zero under recoil while keeping added weight to a minimum. Built with 20 MOA of elevation, the bridge compensates for bullet drop at extended distances, giving long-range shooters more usable adjustment from their scope before running out of internal travel. Its full-length design also opens up in-line mounting space for night vision or thermal optics forward of a primary day scope, a feature favored by tactical and law enforcement end users. Compatible with the Cadex CDX-R7, CDX-SS Seven S. T.A. R.S., factory Remington 700, and most Rem 700 custom clone actions, it's a versatile upgrade for anyone building a dedicated precision or duty rifle.
