Description
LaRue built the RAT Stock around a simple idea: make an adjustable AR-15 stock that feels overbuilt and does its job without any fuss. Molded from glass-filled polymer with metal internals, this OD Green version is meant to ride alongside the LaRue Tactical family of rifles, though it drops onto any standard Mil-Spec receiver extension. It runs about 6.99 inches long and 5.30 inches tall, so it keeps a familiar carbine profile while feeling noticeably more solid than the average stamped-out stock.
What Sets the RAT Stock Apart
The standout feature is the two-stage trigger adjustment. Instead of the usual single-lever release, you pull the mechanism to the rear to unlock, slide to your position, and let it settle into a positive lockup. CNC-machined internals make that action smooth and repeatable, and the internal cavity is cut tight enough to grip the buffer tube without needing an extra locking mechanism. That tight fit is what kills the side-to-side rattle folks complain about on budget stocks. Reviewers consistently call out the fit and finish as some of the best they have handled on a collapsible AR stock.
Sling Options and Onboard Storage
LaRue didn't skimp on the practical stuff. You get ambidextrous 1/4-inch QD swivel sockets plus 1-inch slots, so two-point slings anchor easily whether you shoot lefty or righty. The locking rear buttplate slides open to reveal internal compartments sized to hold cleaning kit components, which is handy if you run LaRue's optional RAT ROD kit.
Fitting the RAT Stock to Your Build
This is a stock-only setup, so you'll want a standard Mil-Spec buffer tube already on your lower. Install is straightforward: depress the adjustment mechanism, slide it onto the tube, and you're running. The OD Green finish pairs nicely with earth-tone builds and matching LaRue furniture if you're chasing a coordinated look. For anyone rebuilding a carbine and tired of stocks that flex or clatter, the RAT lands squarely in the do-it-right category.

Frequently Asked Questions
Does the LaRue RAT Stock fit a standard Mil-Spec buffer tube?
Yes. The RAT Stock is designed to run on standard Mil-Spec AR-15 receiver extensions and locks up positively on each position. The internal cavity is cut for a snug fit, so you get minimal play without needing any add-on locking hardware. Note it will not fit commercial-spec tubes.
How does the two-stage trigger adjustment work?
Rather than a single squeeze lever, you pull the adjustment mechanism to the rear to release the stock, slide it to your desired length of pull, and let it settle back into lockup. The CNC-machined internals make that motion smooth and repeatable. It's a design that lets you adjust from different shooting positions without fighting the stock.
Does the RAT Stock come with the cleaning rod kit or a buffer tube?
No. This SKU is the stock only and does not include the RAT ROD cleaning kit or a buffer tube assembly. The rear buttplate opens to internal compartments sized to hold cleaning kit components if you add the optional kit separately. If you need the tube, buffer, spring, and castle nut, look for the full RAT stock kit version instead.
Is the RAT Stock worth it over a basic polymer stock?
If you value fit and finish, it's a noticeable step up. Owners regularly point to the tight lockup, quality machining, and lack of rattle as reasons it feels overbuilt compared to entry-level stocks. It costs more than a bargain option, but the solid platform and onboard storage make it a favorite for folks building a carbine they plan to run hard.
