Mount Rail Multipliers

mrm45x90 mrm

If you are someone who ascribes to the philosophy that “more rails are more better,” the Mount Rail Multipliers may pique your interest.

AR-Master is showing a product that hangs additional accessory rails off of a flat top receiver. The Mount Rail Multipliers appear to provide either 45º or 45º and 90º rails for sights or even a BattleBlade Wolfhawk HP.

AR-Master makes a number of other interesting products such as the Stock Pivot Adapter (SPA) that allows you to spin an AR-15 rifle while keeping it tight to the shoulder. According to AR-Master, “The SPA lets you turn your conventional rifle into a versatile multi-mission rifle.”



ONLY the SPA enables the shooter to instantly access multiple sights while in a precision, cheek-weld shooting position fixed on the target. Multiple sight rifles offer redundancy in cases of damage to the primary sight, multiple zero combinations, daylight/night sight combinations, and side sight acquisition to aid firing with a gas mask. Additionally when the action is rotated 45 or 90 degrees the pistol grip and hi-capacity magazines protrude to the side and not straight down, aiding lower/narrower defensive operational positions such as beneath vehicles or other horizontal working envelopes.

      If you could get a dollar for each upvote you’ll receive, you’d be able to buy yourself a great Christmas git.

  • BattleshipGrey

    In the configuration shown in the drawing, how would that not interfere with ejection.

    • Andrew Hobby

      Bro, RAILS.



    It’s like orcs, except with more rails instead of more noise.

    You went full ejection port obstructing.

    You never go full ejection port obstructing.

      They forgot to mention that it can double as a case deflector…

      • Zachary marrs

        I’d rather have unobstructed access to the ejection port

        • echelon

          Sorry I forgot the /sarcasm tag. Haha.

  • Andrew Hobby

    When you see the “logic” behind many of their products, it makes PERFECT SENSHES.

    ” You wouldn’t drive a car with only one speed or direction, why would you LIMIT your rifle to one zero?”

  • Mystick

    Too… many… rails….
