    Question for anyone in the know (from someone in the UK),
    This is a SR-25 pattern mag, right? So what is the size difference, etc, between this and the AR-10 mattern?
    I’m guessing that with magpul making SR-25 mattern’s this will become an unoffical industry standard.

    • Slowly the SR25 pattern mag is becoming the standard… DPMS’ large frame AR’s are also SR25 pattern.

      I wish that there was an idustry standard for the large frame AR’s… Would make the accessorie market that much easier to navigate. As it stands, even things that are designed to fit a certain rifle may or may not fit your particular rifle.

    Does this magazine work with the Smith & Wesson M&P 10?
