.350 Legend Complete Upper Receivers
AR15Parts.com builds .350 Legend complete upper receivers to order using barrels from Wilson Combat and Shaw. Every upper is assembled, headspaced, and function-checked in our shop before shipping. The .350 Legend was developed by Winchester specifically for deer hunters in straight-wall cartridge states like Ohio, Iowa, Indiana, and Michigan. It delivers the fastest muzzle velocity of any straight-wall hunting cartridge at 2,300+ fps while generating just 8.5 ft-lbs of recoil — roughly 20% less than a .243 Winchester. The result is a deer-hammering cartridge that's comfortable to shoot all day. Configure your .350 Legend upper with your choice of barrel length, handguard, muzzle device, and optional BCG and charging handle. Purpose-built for hunting, built to your specifications.

How to Choose the Right .350 Legend Upper
Barrel Length & Gas System
.350 Legend uppers are available in 16", 18", and 20" barrel lengths with carbine-length or mid-length gas systems. A 16" barrel creates a compact, maneuverable deer rifle perfect for treestand and blind hunting. Longer barrels add velocity for improved terminal performance at range. The standard 1:16 twist rate is optimized for the cartridge's 150-180 grain bullet weights.
Complete Upper vs. Barreled Upper
Complete uppers ship with BCG and charging handle. The .350 Legend uses the same BCG as 5.56 NATO, so many shooters already own a compatible bolt carrier group. Barreled uppers are available for these buyers.
Key Specifications
Muzzle Velocity: \~2,300 fps with 150gr Effective Range: 250 yards Barrel Twist: 1:16 Recoil: Very light at \~8.5 ft-lbs Platform: Standard AR-15 lower receiver Cartridge Type: Straight-wall (compliant in restricted states)
.350 Legend Upper Compatibility
The .350 Legend uses a standard AR-15 5.56/.223 bolt carrier group. If you own a 5.56 BCG, it works with .350 Legend. However, the cartridge requires a dedicated .350 Legend magazine — standard AR-15 5.56 magazines will not reliably feed .350 Legend ammunition. The upper fits any mil-spec AR-15 lower receiver. Suppressor compatibility is good with standard bore suppressors.
Best Uses for .350 Legend Uppers
The .350 Legend was purpose-built for deer hunting and it excels at this role. It is the top choice for hunters in straight-wall cartridge states including Ohio, Iowa, Indiana, Michigan, and others that restrict bottleneck cartridges for deer season. With 150-grain loads at 2,300 fps, the .350 Legend delivers devastating terminal performance on whitetail deer to 200+ yards. The cartridge's mild recoil makes it an excellent choice for youth hunters, smaller-framed shooters, or anyone who wants to spend a full day at the range without fatigue. Subsonic .350 Legend loads are available for suppressed hunting, adding versatility to an already practical cartridge.
