How to Build Your .350 Legend AR-15: A Comprehensive Guide
Building an AR-15 chambered in .350 Legend can be an exciting project for both new and veteran firearms enthusiasts. This guide aims to provide you with the necessary steps, tips, and components to make the process smooth and enjoyable.
Understanding the .350 Legend
Before diving into the build, it’s essential to understand the .350 Legend round. Known for its versatility and effectiveness, it’s particularly popular for hunting deer and coyote. It’s designed to deliver a flat trajectory and minimal recoil, making it a favorable choice for many shooters.
Essential Components for Your Build
To complete your .350 Legend AR-15 build, here are the key components you’ll need:
Lower Receiver: Ensure it’s marked as multi-caliber so it can handle the .350 Legend.
Upper Receiver: A complete upper in .350 Legend that includes the barrel and bolt carrier group.
Barrel: Opt for a barrel length between 16 to 20 inches for optimal performance.
Handguard: A free-float handguard is recommended for better accuracy.
Buffer System: A standard AR-15 buffer and spring will work, but check if a heavier buffer is required for smooth cycling.
Lower Parts Kit: This kit typically includes everything from the trigger to the magazine catch.
Stock and Grip: Choose based on your comfort and shooting style.
Optics: Consider a red dot or scope suited for the ranges you expect to shoot at.
Step-by-Step Build Guide
Step 1: Assemble the Lower Receiver
Start by installing the lower parts kit into the lower receiver. Pay attention to the trigger and hammer assembly, ensuring they are properly aligned.
Attach the buffer tube, spring, and buffer. This part is crucial for the cycling of the rifle.
Once completed, attach your stock of choice.
Step 2: Prepare the Upper Receiver
Install the .350 Legend barrel onto the upper receiver, ensuring the barrel nut is properly torqued to the manufacturer’s specifications.
Attach the handguard securely, making sure it aligns with the barrel.
Insert the bolt carrier group and charging handle into the upper receiver.
Step 3: Take It to the Range
Once your rifle is assembled, it’s time for a test round! Make sure to break in your barrel properly by following best practices.
Start with a few rounds to ensure everything operates smoothly.
Keep an eye on the performance and make any necessary adjustments, whether it’s to the optics or your shooting position.

I’ve started my .350 Legend AR build! For picking the right barrel length, I’ve read that 16 inches strikes a good balance between velocity and maneuverability. Anyone else have thoughts?
Absolutely! I’ve gone with a 20-inch barrel for better ballistics. It really comes down to what you want to use it for—hunting or target shooting. Both can work well!
Great discussion! I’m currently deciding between a forged or billet upper receiver. Does anyone have strong opinions on which performs better for .350 Legend?
Good point, annyoung! Look for a lower that comes with a good integrated trigger guard; it helps with feeding reliability especially with .350 Legend’s shorter cases.
Haha, I’m just glad I found this discussion before I started ordering random parts. Thanks, everyone! Last question—how much should I expect to spend on a reasonably good build?
I’m excited to see others building a .350 Legend AR! For the assembly, you’ll need an AR-15 lower, upper, barrel, and a few specialized tools like a torque wrench and punch set. Always ensure safety first by wearing eye protection!
Great start, pagedenise! I would also recommend checking if you have all necessary parts like the buffer tube and stock before you begin. It will save you time during the build!
Safety! Definitely don’t forget to clear your workspace and keep the area free of distractions. I learned the hard way once and it wasn’t fun. Let’s build safely!
