Just As Good Rifle.

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


*** Please allow for 2-4 week lead time for parts assembly and QC. ***

Our builder kits consist of a complete upper with a JR BCG, mil-spec charging handle, and complete lower. Both components are ready to be assembled by the end user.

Note: You must be 21+ to purchase a serialized lower. Lower receivers will be shipped to your provided FFL while upper receivers will be shipped to you. 

Barrel: L&S’s 23oz 4150CMV, stress relieved, 1/7 twist mid length barrel is gas nitrocarburized for longevity, and is capable of match grade accuracy with Black Hills® MK262 ammunition. Barrels are batch HP/MPI and accuracy tested at 100yds. Gas port is drilled to 0.078″ for a smoother shooting rifle that retains reliable extraction and ejection in a variety of environmental conditions.

(Inquire about HBAR profile barrels)

Bolt Carrier Group: The JAG utilizes the L&S Standard BCG, a properly heat treated 9310 bolt with a gas nitride coating to keep your AR running flawless.

Handguard: Free floated and secured via wedge locking system, the JAG rail is a durable handguard that retains a continuous 12 o’clock 1913 section and multiple MLOK attachment points for whatever goober-tier accessories you have in mind.

Receiver Set: Borrowed from the ARC, L&S’s 7075 forged receiver set comes with an M16 FCG pocket and Type III hard coat anodizing for added coating longevity.

Gas Drive: L&S utilizes the 4140CMV machined quality gas block (QGB) for paralleled thermal expansion, which is secured to the dimpled barrel via degreased, thread locked, serrated gas block screws torqued to 25 in/lbs.

Trigger: Our LPK includes the Enhanced Reliability Combat Trigger v2 (ERCT v2) borrowed from the ARC to give the JAG a 4lb trigger, with full mass hammer and mil std. springs for reliable primer ignition.

Controls: The JAG comes preinstalled with an enlarged trigger guard, bolt catch, ambi safety, 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
