Each entry highlights who it’s best for, why it stands out, and a practical limitation to consider. Use the buying guide at the end to compare features across options and pick the ideal choice for your build.
Eastern Tactical Supply A2 Buttstock Spacer and 1.2″ Screw Set
This spacer kit is designed for all A2 standard butt stocks and includes a 1.2″ gas port screw. The construction is described as solid machined steel, offering durability in field or range use. It’s best for builders who need a robust, steel spacer with a gas port included for proper alignment and performance. If you’re upgrading an older A2 configuration or replacing a worn spacer, this kit provides a straightforward, screw-in solution. A potential limitation is weight; steel parts add heft compared to aluminum options, which could matter on lighter builds.
K Kexuan A2 Butt Stock Spacer and 1.2″ Screw Set
The K Kexuan spacer set is intended for all A2 standard butt stocks and includes a 1.2″ gas port screw. It features solid machined construction, mirroring the rugged build typical of A2 components. This option is well-suited for cost-conscious builders who want reliable steel insert hardware and a compatible gas port screw. A consideration is availability of exact fit in some non-standard replicas, so confirm compatibility with your specific stock model before purchasing.
WILBUR’S FINEST Buffer Tube Plug
The buffer tube plug from Wilbur’s Finest is tailored for pistol conversion kits and AR22 platforms that do not require a buffer tube. This plug is presented as a must-have accessory to eliminate the need for a buffer tube in compatible builds, offering a clean, simple installation process. Best for AR22 or pistol-conversion enthusiasts who want a streamlined, tube-free setup. A limitation is that it’s not designed for standard AR-15 buffer tube configurations, so it won’t suit clients needing a normal buffer system.
TACPOOL Rifle Length A2 Fixed Stock
The TACPOOL A2 fixed stock kit is described as rifle-length, Matt Black finished, and compatible with upgrading or replacing worn components. It emphasizes MiI-Spec tolerances and high reliability, making it a strong choice for builders who prioritize a standard-compliant stock with consistent dimensions. Choose this if you want a proven, ready-to-install stock set with a traditional look. A potential limitation is that fixed stocks may not suit builders seeking adjustable options for length of pull adjustments.
Midwest Stock Tube Adaptor Picatinny
The Midwest Stock Tube Adaptor Picatinny provides a versatile interface for mounting accessories on the stock tube region. It’s aimed at builders who want to expand compatibility with optics, lights, or other accessories. Best for users who want additional mounting options without changing the core stock tube. A caution is that this adaptor is an accessory component rather than a full spacer kit, so plan compatibility with your overall build and rail system before purchasing.
Buying Guide: Key Purchase Considerations
What is your build? Decide whether you need a full spacer kit, a tube adaptor, or a plug for a tube-less configuration. Consider material (steel vs. aluminum), weight, and durability, especially for field use. Confirm compatibility with your A2 stock model and the screw length required by your gas port design. If you’re replacing a worn spacer, look for a kit that matches standard A2 tolerances to avoid fitment issues.
What are form and function priorities? If you want a sturdy, long-lasting spacer, steel builds from Eastern Tactical Supply or K Kexuan are sensible choices. If you’re optimizing a pistol conversion or AR22 platform, the buffer tube plug from Wilbur’s Finest is especially relevant. For traditional upgrades, TACPOOL’s fixed stock provides reliable performance with standard dimensions. For accessory expansion, the Midwest adaptor adds mounting flexibility without overhauling the stock assembly.
Ease of installation matters. Look for sets with a straightforward screw-in design and clearly marked gas port dimensions. If you’re a first-time builder, aim for kits with clear instructions and compatibility notes. Price is a consideration, but prioritize proper fit and material quality to ensure lasting function.
