Bipod-like Device Instead of the Bean Bag Rest ?!

As you can see from the above picture this little accessory called Extreme Rear Support System (E.R.S.S.) looks like a bipod but it is placed instead of a rear bean bag. And if you look closer, then you’ll see that it is not quite a bipod. So this product is purposely designed to be used instead of the rear support bag. It is made by a company called Rugged Ridge Outdoor Gear.

The E.R.S.S. has four leg angle options. In order to adjust it to the needed angle, you have to press the button located near the pivot point and move the legs until they click into the position. In different positions, it has a different top V-notch or cradle angle and of course different heights. I think before purchasing this accessory, you’d better make sure that it fits the width of your rifle’s stock at its highest position, where the V-notch is the narrowest.

E.R.S.S. is machined from a solid block of aluminum and has polymer inserts in cradle and feet areas. It is also very lightweight weighing only 4.4 oz. The MSRP of this accessory is $125. The price also includes a belt pouch which it comes with.

Here is a video showing how this accessory works:

Despite the good features of this product, I think the rear bags may still have an advantage over it. When using a rear support bag, you basically have infinite position adjustability within its minimum and maximum limits. I mean you can squeeze the bag to get the exact elevation of the rifle that you need for any particular shot. In the case of this device, you have only four positions and heights and a bit more adjustability by sliding it back and forth.

    I’d rather do a monopod than this, and I’d rather do a bean bad than a monopod.

    • Sunshine_Shooter

      Why does a rear bag work so much better than a monopod?

      • Twilight sparkle

        It’s easier to adjust quicker and its better at taming the harmonics of the gun if you’re on a hard surface.

        • Sunshine_Shooter

          That makes sense. Thanks.

  • Form Factor

    Seems like a pain preventing it from tilting for-or backwards… . 3 folding legs on a small U shaped rest would be better!

    And wth call it “extreme” rear support system…. typical marketing garbage names..

    • Form Factor

      (and an inbuild monopod ofcourse is still best anyways)

      • micmac80

        Built in monopods are great for extended period obserwing trought the scope but , realy bad for accuracy. Bean bag by far the best.

        • Sunshine_Shooter

          Why does a rear bag work so much better than a monopod?

          I recently chose to make a rear bag for ~$1.62 after tax instead of paying $100+ for a monopod. It has worked fantastically for me.

  • JT303

    For $125, it’s a ‘hard pass’ from me. Call me a heathen or a luddite, but I can spend far less and get a decent bag, which as Hrachya said, is infinitely adjustable.

  • DanGoodShot

    “you have only four positions and heights and a bit more adjustability by sliding it back and forth.” Not to mention it’s a hundred times more expensive than a bag of sand. Anything to separate you from your money. Imho, it’s completely useless and unnecessary when a good ol’ sandbag is far superior at a fraction of the cost.

  • Keiichi

    Too bad it only has four positions…

    If it had “infinite adjustment” for height I’d consider it as an alternative to carrying a heavy sandbag.

    • ThatOneGuy

      Just tilt it forward or backwards to raise/low it. Just make sure you have enough grip on the stock that it maintains that hold when you lean it over to cover the distance to the next “set” size.

      Still a ton of money for basically the pliers from a toddler toy tool set.

  • Nashvone

    Maybe if I was backpack hunting but then some type of chamois pad on a rock would do just as well and I can leave the rock behind.

  • Tassiebush

    I imagine the point of this is to have the benefit of a bag in the field hunting without the weight and bulk. It’s not really that appealing for range use unless the range you use isn’t actually a range but rather it’s a spot that involves quite a bit of walking.

    • Dougscamo

      I have used my binoculars in the past when push came to shove….quite handy!
      But they do make small, lightweight “beanbags” that don’t really add much weight and you provide the bulk by squeezing them with the non-trigger hand resting on the toe of the stock….quite handy as well and not so hard on the binoculars…

      • Tassiebush

        That binocular approach is an idea that has never occurred to me but it makes sense. With rests in the field it’s any port in a storm.
        I’d imagine a foam filled bag could be made. Probably is made actually. I currently just use trouser legs cut off and tied off into sand bags with stuff scooped off a local beach then just shove a jacket under the stock or I just shoot off my pack but I’ve been thinking about how to improve it all.
        I was thinking about making tripods with sticks. I might do that for the front and pinch some foam offcuts to put in a orphan sock for the other one.

    • iksnilol

      Why do you need rear support in the field? It’s not like there are wild shooting tables everywhere out in the boonies.

      • Tassiebush

        I don’t think it’s always or often needed but sometimes if the position is difficult and particularly if you’re on a ridge shooting down it can help to have something to stuff under the rear end of the stock.

        • iksnilol

          I just use my fist.

          • Tassiebush

            Eeew phrasing man!

          • Tassiebush

            I normally do too. Occasionally I need to put something under my fist to get the elevation right.

  • Bradley

    Yes it is “quite a bipod.” Bipod=two legs. It’s a bipod. How is it not a bipod?

    • FOC Ewe

      Yeah, a t-shirt stuffed in a crown royal bag works well for a lot less than $125..

      • Bradley

        What does that have to do with the definition of “bipod?”

        • kyphe

          It is a bipod in the simple definition but it does not quite fit the expected much narrower criteria for a rifle bipod. It is not fixed to the rifle and it is not two legs from a central supporting hub that is of fixed form to enable the connection with the rifle. It looks like someone improvised with a large pair of scissors and though hmm this could sell lol. Now ofc rather than saying “not quite a bipod” you could more accurately say “not a traditional bipod”

  • Sua Sponte

    The MSRP of this accessory is $125…….I like that individuals are attempting to come up with concepts that fit the needs of the community or provide improvement, don’t really see either in this, especially for $125…How about a concept where a smaller version of a bipod that can be attached to the stock via a thin strap or velcro or possibly a small block rail that attaches to the stock giving the ability for quick and easy removal of the bipod?…Just thinking out loud, there might be something out there like that..

  • Joe F.

    What keeps it from falling over when you move the rifle forward or backwards? It might be answered in the video, which admittedly I didn’t watch, since I lost complete interest when I seen the price. Ummm, no thank you.

  • MiamiC70

    $125? GTFOH

  • It’s called the “extreme rear support system” and nobody made a James Reeves joke?

    • Dougscamo

      Now THAT’S funny….

  • Tiru Maru

    Can most likely do the same thing with a pair of pliers, for a hell of a lot less money.

  • Goody

    In prone I never had much difficulty with just using my hand under the butt plate. 1.5″ isn’t ideal for long range hunting or load development, but it’s way better than my ability to read wind, and also preferable to carrying junk around all day.

  • iksnilol

    Can’t you just mount a smaller bipod on the rear sling swivel? Assuming it is on the bottom of course.

  • As a sniper I like the concept, and the very light weight this rest offers. However, the final product falls short on several points. First, only 4 positions is not acceptable for extremely fine-tuned precision shooting. This might help in some hunting or range shooting situations, but highly precise and longer distance shots require a much greater latitude of adjustment. The price is unacceptably high, for the level of adjustment offered. Finally, I’m not convinced this rest would remain in place with heavier .30 caliber recoils.

    Now, if they could provide a sliding adjustment range with a manual locking mechanism that is easy to manipulate, and a more secure footing, this could be an option worth looking into (though with a price of around $50).
