The famous Barrett M82A1 rifle, chambered in .50BMG (12.7x99mm), has been in use by militaries around the world since its introduction in 1982. It is also quite popular with civilian shooters in the United States – those that can afford the $10,000 price tag, that is.
It has since been chambered in .416 Barrett (10.6x83mm), which was developed in 2005 and employed mainly in the Barrett M99 single-shot rifle. Barrett has now introduced a conversion kit which will enable owners of the .50 BMG M82s and M107s to fire .416 Barrett. The price is $3,000.
The kit comes with, according to Barrett, “everything you need to convert your Model 82A1 .50 BMG rifle into a rifle chambered for .416 Barrett: Barrel assembly, battery bumper, muzzle brake, muzzle brake nut, and one 10 round magazine.” However, a complete bolt assembly is also in the photograph. Since .50BMG and .416 Barrett have nearly identical base diameters (.804″ and .797″, respectively), it would not seem necessary to use a different bolt.
