The Redi-Catch for MSRs by Boonie Packer

I first saw the magazine release doubling as a bolt catch on the ADAC lower receivers by AXTS Weapon Systems and found it highly useful. Expanding the same functionality, albiet with an external spring, is the Redi-Catch, a product from Redi-Mag. 

Using a S-shaped steel sprint, anytime the magazine catch is pressed, a spring pushes against the bolt catch. When the charging handle is pulled, the bolt will be locked to the rear, a highly useful combination for clearing a double-feed malfunction or unloading and showing clear.

Redi-mag has two videos of the Redi-Catch in action. One as a stand-alone device and another used in conjunction with the Redi-release, a BAD lever type system.

Those interested can pick one up on their website.

    Hmmmm… I may actually give this doodad a try.

    I like it. Ares Armor did something very similar about 5 years ago, but you had to remove the bolt catch to install it. I still have it, just not on my rifle.

      Ares Armor sold the FCD by RevEng. The company has been out of business for years and the product is no longer available. This is a superior design though, as it is easier to install and doesn’t marr up the bolt latch.

      • Squirreltakular

        Definitely. Didn’t know it was someone else’s product, though. Good to know.

    Hm, what if you wanted to hold open the bolt but not eject the magazine?

    • Mags!

      Then you wouldn’t press the mag release……….

      • Grindstone50k

        So then you’d have to use the traditional bolt-hold open paddle? I don’t see how this is any sort of improvement over a BAD-Lever type design.

        • Squirreltakular

          Because it halves the step to clearing double-feeds and other malfunctions. Instead of 1) move support hand to bolt catch, 2) remove rifle from shoulder, 3) remove firing hand from grip and lock bolt to rear, 4) reestablish firing hand grip, 5) press mag release, 6) remove mag; it’s now 1) press mag release, 2) use support hand to lock bolt, 3) remove magazine.

          Plus, it doesn’t need gravity to work like those levers do. If I was lying on my side shooting around an obstacle, those levers wouldn’t work.

          • Grindstone50k

            You skipped over the part about the BAD Lever type device. Which would entail 1)move finger to lever 2)Use support hand to lock bolt to rear. With this device it would be more of 1) move support hand to magazine 2)depress mag release 3)stow mag 4) move support hand to lock bolt to rear

            Honestly, I can’t think of a common reason right off the top of my head, but that doesn’t mean anything.

          • Squirreltakular

            I know, I just have a bias against the BAD lever and anything like it. May be justified or not.

            No, it doesn’t stop you from using the bolt catch as usual.

    A little on the expensive side for what it is but seems like a pretty well thought out idea.

  • WB

    I like it, its clever.
    It does have potential for debris to lodge behind the redi-catch preventing magazine engagement and potentially dropped mag. However, low risk enough to not be a disqualifier.
    Biggest downside: $35 seems steep. But I’ll probably try one anyway…
