    Best MLOK for MPX

    Posted by Keg on Oct 31st 2017

    Fit and function are flawless, simple install, looks and feels 1000 times better than factory rail system. Finish matches my GEN 2 receiver perfectly. Highly recommend for MPX owners who want a solid MLOK system.

    Swapped out the handguard on my MPX-K. Looks and feels great. Much better than the factory handguard. Wish you didn’t have to swap out the latch from the factory handguard but I don’t plan on going back so not a big deal.

    Great K Handgaurd!

    Handguard fits great on my MPX with 5" barrel. Extended undercut leaves more room for my hand while still making it safe to shoot the shorter barrel and with an added unique style.
