The Hawkins Precision Short Action Magazine 6BR/Dasher Cases Spacer Kit is engineered to adapt Hawkins Precision short action Hunter magazines for use with 6BR and 6mm Dasher-style cartridges, which typically have a shorter overall length than standard short action loads. Upon installation inside a compatible short action magazine, this kit creates an internal magazine length of about ~2.5in, improving feeding reliability for these cartridges. The kit includes a dedicated spacer, a matching follower, and a new spring, making it a complete solution for converting your stock magazine for BR/Dasher use without needing to modify the original spring.
