Description
You’re a left-handed shooter staring down a sea of right-handed AR-15s. You want a dedicated varmint rifle that doesn’t break the bank, but off-the-shelf lefty options are either custom-shop expensive or non-existent. Where’s the value play for the southpaw precision hunter? The answer is a factory-built rifle that addresses the core lefty annoyances without venturing into boutique pricing.
The Rock River Arms LEF-T LAR-15 LH Varmint A4 AR-15 SA 223 /5.56 20″ Barrel, A2 Stock Black, 20rd is a left-handed, semi-automatic rifle built for varmint and target shooting. It features a dedicated left-ejecting upper, a 20-inch heavy barrel for accuracy, and an A2 fixed stock, offering a purpose-built platform for left-handed shooters at a mid-range price point of $1447.46.
Here’s the thing—the real value isn’t just in the left-hand configuration; it’s in the complete, ready-to-shoot package. Rock River Arms delivers a rifle that’s drop-in ready, requiring no gunsmithing or parts swapping to get a left-ejecting, brass-in-the-face-free experience. This is a huge cost saver compared to buying a standard AR and then paying for a left-handed bolt carrier group, upper, and gunsmith labor. The 20-inch heavy barrel is the cornerstone of this rifle’s mission. It provides the longer sight radius and added weight up front that serious varminters and target shooters crave for stability and consistent accuracy. The 1:8 twist rate is a practical sweet spot, effectively stabilizing a wide range of .223 Remington and 5.56 NATO ammunition from lighter varmint loads to heavier match projectiles.
The fixed A2 stock is a nod to pure function and value. It eliminates the cost and potential wobble of an adjustable stock, providing a solid, repeatable cheek weld. Combined with the rifle’s overall length of 39 inches, it creates a stable shooting platform ideal for benchrest or prone positions. Weighing in at approximately 8.6 lbs unloaded, the heft further aids in managing recoil and maintaining sight picture for follow-up shots. This rifle is built on a mil-spec foundation, meaning a wide array of aftermarket triggers, grips, and accessories from brands like Geissele, LaRue, or Magpul will be compatible if you choose to customize later.

Pros: True left-handed ejection solves the primary annoyance for southpaws. The 20-inch heavy barrel is ideal for precision varmint work. Comes as a complete, shoot-ready rifle. Fixed A2 stock offers stability and reduces cost. Priced well below most custom left-hand builds.
Cons: The fixed stock cannot be adjusted for length of pull. The rifle is heavier than carbine-length ARs, less ideal for dynamic shooting. The fixed carry handle limits modern optic mounting options without an adapter.
This rifle is for the left-handed shooter who is tired of adapting to right-handed gear. It’s for the hunter or target shooter who prioritizes a stable, accurate platform for longer-range work on prairie dogs, coyotes, or paper. It’s a practical choice for someone who wants a dedicated lefty rifle but needs to justify the cost against standard models—this package delivers that specific functionality without a custom price tag. If you need a lightweight, adjustable tactical carbine, this isn’t it. But if you want a left-handed varminter that works fits out of the box, this fills a niche few others do.
Frequently Asked Questions
Q: Is the barrel threaded for a muzzle device?
A: No, the barrel on this Varmint A4 model is not threaded. It features a target crown. This is common on dedicated varmint/target barrels to maximize accuracy potential and maintain a clean profile.
Q: Can I use standard AR-15 magazines with this left-handed model?
A: Absolutely. The lower receiver is a standard mil-spec design. It accepts all standard AR-15 pattern magazines, including popular PMAGs from Magpul and USGI aluminum mags.
Q: Does the fixed carry handle come off to mount a scope?
A: The carry handle is integrated into the upper receiver as part of the A4 design. To mount a modern optic, you would need to use a scope mount that attaches to the carry handle’s rail, or replace the entire upper receiver assembly.
