The Hawkins Precision Long Action Magazine PRC/SAUM Cases Spacer Kit is a purpose-built spacer designed to modify Hawkins Precision Hunter Long Action magazines so they can reliably feed long-case cartridges such as 6.5 PRC, 7 SAUM, and 300 WSM. When installed inside a compatible Hawkins long action magazine, the spacer extends the internal length to approximately 3.350in–3.356in, allowing room for longer bullets and overall cartridge lengths without requiring a new magazine spring — the factory spring is reused. This solution is ideal for hunters and precision shooters who want to adapt existing long action magazines for extended length rounds without compromising feed reliability.
