New Magpul UBR 2.0 Stock

magpul-ubr-20

Magpul just debuted a new and improved stronger, lighter and more affordable 2.0 version of their UBR stock. Their first Utility/Battle Rifle(UBR) stock was pretty darned good and it was very popular, that doesn’t mean there wasn’t room for improvement however. The UBR 2.0 stock is compatible with carbine and A5 length buffer tubes and is designed to take the increased shock and impact from ARs chambered in larger calibers yet it’s around five ounces lighter than the 1.0 UBR stock.

It features a fixed cheek piece to maintain a consistent cheek weld and can still be adjusted to 8 different length of pull positions. It also comes with a front and rear QD sling points, two footman’s loops, storage compartment that’s customizable and a MOE SL angled-toe rubber butt pad. The new Magpul 2.0 UBR stock will retail for $199.95 and should be released in the summer of 2016, that’s $65 cheaper than the MRSP of the 1.0 UBR stock. It will be available in black, flat dark earth, stealth gray and olive drab green. Check out Magpul.com or Magpul’s awesome video below for more info.

    I love Magpul, but I can’t justify $200 on a stock. Sigh, guess I’ll stick with the ‘low-end’ Magpul stocks I already have…

    • JumpIf NotZero

      This is a rock solid stock AND an A5 length buffer tube as well. It’s $200 MSRP and you can subtract the receiver extension away.

      It’s a pretty great deal.

      • Cal S.

        OH! I didn’t even notice that. So, that makes the whole thing lighter… interesting.

  • TheSmellofNapalm

    Personally I think this would be great for an SBR build. Something where you don’t have a lot of weight up front.

    • iksnilol

      Wouldn’t that make it rear heavy? Or do you think in conjunction with a suppressor it would be well balanced?

      • TheSmellofNapalm

        I think one of the reasons some folks like bullpups so much is because they’re rear heavy: you can control the rifle more when the weight is towards the rear. I also think as far as mobile platforms, ie non-prone, this stock would perform best with very short barrels like on a Blackout gun, so you have a strong rear anchor to support a fast shoulder-up. IMHO

        • iksnilol

          I am thinking that something rear heavy will pivot more easily.

          Balanced is the way to go IMHO.

          • Some Guy

            If you’re pulling the stock into your shoulder than the pivot point is at the contact point between the stock and your shoulder.

            Added weight near the pivot point has less of an effect than added weight well in front of it.

  • Christian Hedegaard-Schou

    The UBR was always a great idea, but SO FREAKING HEAVY for a fast go-to carbine.

    I used one on my .458 SOCOM build explicitly for the extra weight, but the price was still a difficult swallow.

    A lightweight less expensive version is exactly what this stock needs.

  • Kyle

    Well now i’m glad that I didn’t get an original UBR lol. Still too heavy for a light carbine but I would definitely want one of these for a full length rifle. Maybe I’ll put one on that Armalite National Match rifle I was eyeballing at the store last week.

  • JumpIf NotZero

    It makes sense to use the A5/SR-25 length so they don’t need an AR-15 and AR-10 versions… But this is still such a big boost for the A5 buffer system. All their new stocks use A5 length.

    Good job Magpul.

    • G0rdon_Fr33man

      What is the difference and purpose of an “A5” buffer tube, contrary to an A4 or lower?

      • The A5 designation comes from Vltor’s attempt to make a retracting stock replacement for the USMC’s M16A4 rifle’s fixed stock. The speculation was that the new configuration might be designated the M16A5. Simply exchanging the standard M4 carbine receiver extension and buffer was considered inadequate by the US Army and USMC. The Vltor A5 ends up with a receiver extension slightly longer than the M4 carbine’s receiver extension. The A5 buffer is slightly longer, splitting the difference in the number of internal weights between the rifle and carbine buffer. The extra length also allows the A5 buffer to use a rifle length action spring.

        The US Army ended up selecting a collapsing stock system for the M16A4 rifle using the “H6” buffer. The latter is roughly a standard carbine buffer body with six smaller weights instead of the three weights used in a standard buffer.

        • JumpIf NotZero

          Exactly right.

          It should be said though the H6 does remove bolt bounce, but is pretty ineffective for reducing cyclic rate or gets you the merits of the rifle spring.

          In this case the military picked the low cost and lesser performing option.

          Most people “in the know” with ARs are switching to A5 buffer systems. Magpul making a point to call it out validates and promotes this.

          • TheSmellofNapalm

            What about other custom buffer lengths like in the KAC SR-15? You wouldn’t want to marry a Knights upper to an A5 lower, would you?

        • G0rdon_Fr33man

          Thank you for the reply. Cleared things right up.

  • Kevin Harron

    Gotta admit, I think it’s kinda fugly.
