ABA Rifle

American Built Arms announced the company will show the new MOD*X GEN III Modular Rifle System at the SHOT Show in Las Vegas. The chassis is designed to be a lightweight drop-in for the Remington 700 short action. The unit weighs about three pounds and two ounces.

The chassis is made of aluminum and is hard coat anodized. The forend has KeyMod attachments on three sides. The rear uses a A*B Arms Fixed-Adjustable Urban Sniper Stock, but can be fitted with any AR-type buttstock. The company also ships the chassis with a A*B Arms SBR P*Grip. It can also be swapped out for any AR-type pistol grip.

American Built Arms states the chassis will work with AICS-style magazines in both .308 and .223/.300AAC sizes. A push button style magazine release is located at the front of the trigger guard. The company states that all after market triggers will work in this unit.

“Over the past year, we received excellent, constructive feedback from a variety of law enforcement, military and competitive precision shooters who gave us some really great ideas on how to enhance the existing MOD*X,” said Jason Combs, President and Founder of American Built Arms Company. “We listened to their feedback and the result is the MOD*X GEN III Modular Rifle System.”

The company expects to ship these units in January. Currently, pre-order pricing is set at $799.99 for a black version and $899.99 for a dark earth colored one.

American Built Arms puts out a variety of AR parts and accessories like this AR essentials kit and this vertical grip.

  • Spencerhut

    Nice looking chassis. A whole lot more people need to buy these bolt action chassis to bring the price down to a reasonable level. Magpul may put many of these chassis makers out of business with their “Hunter” series of stocks.

    • Joseph Smith

      “price down to a reasonable level” is worth repeating.

      No piece of aluminum should cost $800. That’s more than the rifle itself.

      • JumpIf NotZero

        Economy of scale. There are many times more rifles made than these stocks.

        You want to complain about the price. Try making one. You go out and make a single copy of this and let us all know then how unreasonable $800 retail is. You’d be first in line to buy the next one.

        SMH… People who have never built things.

        • Joseph Smith

          This isn’t a one-off prototype or custom build, this is a chassis in production, sold to the pubic.
          The denominator isn’t one. If the math is hard, I can draw you a picture.

          • SJR

            “in production” means many different things. Automotive production is way different than the production of this chassis. How many of these will they sell this year? 1000, 2000, 500?

            You clearly don’t understand manufacturing. “no piece of aluminum should cost $800” Really? How do you account for the X number of machine time, material cost, plating, the hours and hours of r & d?

            And yes, I agree the math isn’t hard. Want someone who know manufacturing to draw YOU a picture?

        • BattleshipGrey

          We’re trying to help them out by telling them how they can sell more, by lowering the price. They’re clearly trying to only reach the market of guys that can afford to drop $3000 on a bolt gun with $2000 optics. That market DOES exist, but I doubt very much that it’s a large market.

          I get that they’ve got to recoup their cost on equipment and material and time, and it’s a risk selling lower to a bigger market, just like it is selling higher to a smaller market.

          I hope this company does well with this stock, it looks pretty good. But the average Remington 700 can’t justify this cost, even if he wants to.

    Last thing we need: more rails!!!

  • I feel like getting that new Ruger rifle would be a better deal in the long run than this, even if it would be a couple pennies more than this stock + rem700 action/barrel.

    • Stan Darsh

      I was about to say the same thing. Actually, I believe it was KY Gun Co that was selling the Ruger Precision Rifle on special for $1050 a few weeks ago.

      • Oh wow, I didn’the know they were that cheap!

        • Stan Darsh

          Unfortunately, I wasn’t aware of the sale until they were sold out. Hopefully they will have a good sale like that again soon, That is a hell of a bargain.
