Barrett's M82A1 has a long-standing reputation among .50 BMG shooters as a rugged, dependable semi-auto platform, and owners typically report the recoil-operated action cycles smoothly despite the size of the cartridge. The most common complaint is how much it costs to keep feeding a rifle chambered in .50 BMG compared to standard rifle calibers.

Moving the rifle in the field is a two-person job for some owners given its bulk, though the quick-detach bipod and M-LOK handguard make it manageable once set up on a bench or in a fixed position. The fluted barrel and muzzle brake are frequently credited with cutting felt recoil for a rifle this size.

Commemorative editions like the America's 250th series draw interest from collectors as much as shooters. Owners of limited runs like this note it holds its value differently than a standard-configuration M82A1, since the finish and serial numbering make each rifle harder to replace.
