Hunters in states that restrict bottleneck rifle cartridges during deer season now have access to four large-bore AR-15 upper assemblies built, headspaced, and function-checked at AR15Parts.com's Denison, Texas facility. The retailer stocks complete and configurable uppers in 350 Legend, 450 Bushmaster, 458 SOCOM, and 50 Beowulf, covering the full spectrum of straight-wall cartridges that qualify under current hunting regulations in Ohio, Indiana, Iowa, Michigan, Illinois, West Virginia, Maryland, Minnesota, Pennsylvania, Arkansas, and Tennessee.
The straight-wall cartridge category has expanded steadily over the past decade as formerly shotgun-only states began permitting rifles chambered in cartridges with no bottleneck taper. For 2026, the list grew again. Michigan's Natural Resources Commission eliminated the Lower Peninsula rifle line, opening qualifying straight-wall rifles to more of the state this fall. Tennessee's Fish and Wildlife Commission approved single-shot, straight-wall cartridge rifles on private land for the first time, effective Nov. 14-20, 2026.
Each caliber AR15Parts.com stocks addresses a different use case. The 350 Legend fires 150-grain projectiles at 2,300-plus feet per second with approximately 8.5 foot-pounds of recoil, making it the lightest-kicking option and a strong fit for youth hunters or all-day sits in a treestand. The 450 Bushmaster pushes 250-grain bullets at 2,200-plus feet per second and has become one of the most widely adopted straight-wall deer cartridges in the Midwest. The 458 SOCOM handles projectiles from 250 to 600 grains and pairs particularly well with suppressors when loaded with heavy subsonic rounds. The 50 Beowulf, firing .50-caliber projectiles from 300 to 400-plus grains, delivers the heaviest close-range impact available on the AR-15 platform.
"A hunter in Ohio filling a whitetail tag has very different requirements than someone in Michigan building a suppressed hog gun," said the Operations Manager at AR15Parts.com. "We carry all four straight-wall calibers so builders can match the cartridge to the animal, the terrain, and the state they are hunting in, rather than defaulting to whatever a single-caliber retailer happens to stock."
All four calibers are available in multiple barrel lengths, with options ranging from 10.5 inches to 20 inches depending on the cartridge. Barrel materials include 4150 chrome moly steel and Satern 416R stainless steel match-grade options. Every upper is assembled at the company's 4000 Texoma Parkway location, where each unit is headspaced, inspected, and function-checked before shipment. Because upper receivers are not classified as firearms under federal law, all configurations ship directly to the buyer's address with no FFL transfer required.
Buyers can configure each upper with their choice of handguard length, muzzle device, and optional bolt carrier group and charging handle. The 458 SOCOM and 50 Beowulf require dedicated bolt carrier groups, which are available as add-on components during the build process.
