Just As Good Rifle.

The beauty of the Stoner platform lies in its modularity. The JAG lower offers a reliable and fully equipped option for new users to grow with and experienced shooters to head straight to the range with the addition of an upper receiver.

  • Enhanced Reliability Combat Trigger

    Our Enhanced Reliability Combat Trigger (ERCT) is borrowed from the ARC to give the JAG a sub 4lb trigger, with full mass hammer and mil std. springs for reliable primer ignition.

  • Ergonomic Controls

    The JAG Lower comes preinstalled with an enlarged trigger guard and bolt catch for ease of operation.

  • Thril® Furniture

    The JAG Lower comes with ergonomic black Thril® Furniture featuring a fixed stock.

  • 7075 Forged

    The JAG Lower is a 7075 forged receiver with Type III hard coat anodizing for added coating longevity. Available in Charcoal, Earth, and Olive.


Note: You must be 21+ to purchase a serialized lower. Lower receivers will be shipped to your provided FFL. Please allow for 1-2 week lead time for parts assembly and QC.

Controls: The JAG comes preinstalled with an enlarged trigger guard, bolt catch, and ergonomic Thril® furniture.

  • Finish Disclaimer

    The JAG, like our other products, prioritizes function over aesthetics; it is completely normal (and even expected) that your rifle will have small imperfections including forging marks, striations in the anodizing, tooling marks from our various CNC operations, handling marks from the test fire procedure, and varying shades between the aluminum. All L&S aluminum components are finished in Type III hard coat anodize because of its surface hardness, abrasion resistance and chemical resistance. Type III adds a 0.0015” layer of hard aluminum oxide to the substrate's surface. This layer is grown via a proprietary, several step electrolytic bath that prioritizes surface protection over all else, and the resultant color is dependent upon the saturation of compounds in the various baths, dye concentration, dye mix ratio, aluminum oxide case depth, starting smoothness of the part, etc. Rails, receivers and other aluminum parts can and will vary from one part to the next, even within the same batch. It is nearly impossible to have a perfectly matching JAG, thereby making each rifle unique. The photos above are a representation of what you will receive, but it may not be a 1:1. Even with the inherently inconsistent nature of anodizing, we consciously selected Type III Ano for surface finish longevity--to date, there is no cerakote (or other painted finish) that can beat it.

    I’ll have to come back and add or edit as I haven’t fired the lower yet and dislike reviews that show them but fit and finish are fantastic. The olive anodize is sharp. Slapped it on an 18″ SPR upper and the trigger feels really clean and crisp. Knocked it out of the park based on looks. Customer service from L&S is fantastic so I know if there is an issue, they’ll take care of me.
