Choate Tool Thompson Encore M4 Telescoping Stock Review

Does the Choate Tool Thompson Encore M4 Telescoping Stock Deliver?

The Choate Tool Thompson Encore M4 Telescoping Stock is an intriguing aftermarket accessory for the Thompson Encore platform, aiming to bring modern adaptability to a rifle known for its versatility. This combination unit replaces the traditional fixed stock with an adjustable, AR-15 compatible M4-style telescoping stock. My personal quest for a more dynamic and user-friendly shooting experience on my Encore was the driving force behind exploring this upgrade. The standard Encore stock, while functional, lacked the adjustability needed for quick transitions between different shooting positions or for accommodating multiple shooters. My initial impression of the Choate offering was one of pragmatic design; it’s clearly engineered to serve a specific purpose without unnecessary embellishment. I briefly considered other adjustable stock solutions, but the direct integration offered by this Choate adapter seemed the most straightforward path. Unboxing this unit brought a sense of practical satisfaction, a feeling that a common shooting limitation might finally be addressed.

Real-World Testing: Putting Choate Tool Thompson Encore M4 Telescoping Stock to the Test

First Use Experience

My testing grounds for this stock were primarily the range and a few extended field excursions, replicating scenarios where variable shooting positions are common. The initial installation was straightforward, involving the aluminum adapter screwing into the Encore receiver grip, which then accepted standard AR-15 buffer tubes and stocks. I tested it in a variety of weather conditions, from warm, dry days to a light drizzle, and it performed without issue. The telescoping mechanism felt secure, even after multiple adjustments.

The ease of use was a definite plus; the familiar push-button adjustment of an M4 stock is intuitive for anyone with even a modicum of AR platform familiarity. My only initial quirk was ensuring the adapter was fully tightened, as a slightly loose fit could lead to minor wobble. Once secured, however, the connection felt solid.

Extended Use & Reliability

After several months of regular use, including multiple range days and a couple of hunting trips where quick adjustments were essential, the Choate Tool Thompson Encore M4 Telescoping Stock has held up remarkably well. The aluminum adapter shows no signs of stripping or stress, and the polymer stock itself, though polymer, feels robust enough for its intended purpose. There’s been no noticeable degradation in the telescoping action, and it remains smooth and positive.

Maintenance is minimal, primarily involving a quick wipe-down with a cloth to remove dust or debris from the buffer tube and stock. I did occasionally re-check the tightness of the adapter, but it rarely needed more than a quarter turn. Compared to some aftermarket adjustable stocks I’ve used on other platforms, this one feels more integrated and less prone to developing slop over time, likely due to the direct adapter connection.

Breaking Down the Features of Choate Tool Thompson Encore M4 Telescoping Stock

Specifications

The core of this accessory is the aluminum adapter housing, which is the critical component that bridges the Thompson Encore’s receiver grip to the standard AR-15 buffer tube threading. This allows for the attachment of any AR-15 telescoping stock, providing a vast array of options for length of pull and cheek weld customization. The included telescoping stock offers a length of pull range from 12 3/4 to 16 inches, a substantial adjustment that caters to a wide spectrum of shooter sizes and gear configurations.

The polypropylene construction of the stock itself is a common material choice for AR stocks, offering a balance of durability, weight, and cost-effectiveness. This specification means the stock is relatively lightweight, contributing to the overall balance of the firearm. It’s important to note that All NFA Rules apply, and federal law prohibits use with barrels shorter than 16 inches, a crucial safety and legal consideration for any rifle modification.

Performance & Functionality

The primary job of the Choate Tool Thompson Encore M4 Telescoping Stock is to provide adjustable length of pull to the Thompson Encore platform, and it excels at this. The ability to quickly dial in the perfect length of pull significantly improves shooting comfort and accuracy, especially when transitioning between different shooting stances or wearing varying thicknesses of clothing. The secure lock-up of the telescoping mechanism prevents any unwanted movement during recoil or while shouldering the rifle.

A key strength is its universal AR-15 stock compatibility, opening up a world of aftermarket choices. The main weakness, if one can call it that, is the adapter itself relies on a secure thread-in connection; while robust, proper installation is paramount for optimal stability. It meets and generally exceeds expectations for an adapter of this type, offering a marked improvement over fixed stocks.

Design & Ergonomics

The design of the Choate Tool Thompson Encore M4 Telescoping Stock is functional and focused on adaptability. The aluminum adapter is the most substantial part of the assembly, finished in a utilitarian matte black that blends well with most firearm components. The telescoping stock itself is a standard M4-style design, which is ergonomically sound for many shooters, offering a familiar grip and profile.

The adjustment mechanism, a simple push-button release on the stock, is easy to operate, even with gloves on. The length of pull adjustment is smooth, and the detents that hold it in place are positive and secure. There’s a slight learning curve for ensuring the adapter is perfectly seated and tightened, but once that’s done, the overall ergonomics are a significant upgrade for shooters who prioritize adjustability.

Durability & Maintenance

The Choate Tool Thompson Encore M4 Telescoping Stock appears to be built for reasonable longevity under typical use. The aluminum adapter is the most durable component, and it’s unlikely to fail unless subjected to extreme abuse. The polymer stock is also quite resilient; I’ve yet to see any cracks or significant wear after consistent use.

Maintenance is refreshingly simple. A damp cloth and perhaps a bit of silicone lubricant on the buffer tube occasionally is all that’s needed. There are no complex parts or seals to worry about. Potential failure points would likely be the spring-loaded detent on the telescoping stock, but this is a common wear item on any M4-style stock and is typically replaceable.

Accessories and Customization Options

The primary “accessory” of this system is the ability to use virtually any AR-15 telescoping stock. This means you can swap out the included stock for models with enhanced cheek risers, different grip textures, or even integrated sling attachment points. The aluminum adapter is the crucial piece that unlocks this vast ecosystem of customization for the Thompson Encore.

The adapter itself is the core offering, and while no other specific accessories are bundled, its compatibility with the massive aftermarket for AR-15 stocks is its greatest asset. This allows users to tailor the fit and feel precisely to their needs, which is a level of customization rarely found for the Encore platform in this manner.

This upgrade is ideally suited for Thompson Encore owners who frequently shoot from varied positions, share their firearm with others of different statures, or simply desire more ergonomic customization. It’s perfect for the shooter who wants to adapt their Encore for disciplines that benefit from a precisely fitted stock, such as certain types of hunting, range shooting, or even some modern muzzleloader competitions where adjustability is key. Those who already own AR-15 components will find this particularly appealing due to the ease of integration.

Anyone seeking a permanent, ultra-lightweight solution, or those who are unfamiliar with AR-15 accessory interfaces, might want to consider alternatives or invest time in proper installation. For optimal use, having a selection of AR-15 stocks or the intent to purchase one would maximize the value of this adapter. I would also recommend having a good torque wrench or thread locker on hand, just to ensure that aluminum adapter stays perfectly seated.
