PSA 10.5″ Carbine-Length 5.56 NATO SBA3 Pistol Kit.
Solve Your Custom Build Concerns: If you’ve hesitated on starting a custom rifle or, in this case, pistol build because it sounds too complex or costly, this kit is a great place to start. It comes with a complete upper receiver with a barrel, bolt carrier group, and charge handle. It also has everything you need for the lower half of your AR-15, eliminating the guesswork and the hassle of sourcing all the small parts separately. By pairing this with a compatible lower receiver, like the PSA AR-15 “Stealth” Lower, you’re set with a high-quality foundation that’s both cost-effective and straightforward to assemble.

What’s Included? This kit isn’t just affordable; it’s also packed with high-quality components:
- Barrel: A 10.5-inch 4150V Chrome Moly vanadium steel barrel, nitride treated for durability and precision, with a 1:7 twist rate perfect for a variety of bullets.
- Complete Upper Receiver: In 5.56 NATO with a forged 7075-T6 aluminum, mil-spec, barrel hard-coat anodized for maximum durability.
- Handguard: PSA 12″ Slant End M-Lok, offering ample space for attachments.
- Muzzle Device: A sleek PSA Fluted Flash Can that directs muzzle blast forward, away from the shooter.
- SB Tactical SBA3 5 Position Adjustable Arm Brace: The SBA3 is 5-position adjustable and dramatically enhances versatility. It can accept a mil-spec carbine receiver extension and features a minimalist design with an integral, ambidextrous QD sling socket.

Tools & Extras You’ll Need: While the kit includes most of what you need, here are a few extras to pick up:
- Lower Receiver: Grab a PSA AR-15 “Stealth” Lower receiver [this is the part that needs to go to your FFL] to match with your kit.
- Tools: A set of punches, a brass hammer, and an AR-15 armorer’s tool will make assembly smooth and prevent any marring of your components.
Assembly Tips:
- Start Small: Begin with the lower receiver. Installing the trigger assembly and safety selector first can make the rest of the process easier.
- Take Your Time: Ensure each pin and screw is correctly placed and tightened. Misalignments can affect functionality.
- Check Alignment: Regularly check the alignment of all parts as you assemble to ensure everything operates smoothly once fully assembled.
- Get Help Online: There are tons of great step-by-step videos out there.
