Mach2 Conversions Warning
Brownells has recently been informed by ATK Alliant Techsystems
(parent company to CCI/SPEER) that converting .22 caliber rimfire
semi-automatic firearms to the new Hornady .17 Mach 2
caliber could result in premature exposure of the fired cartridge
resulting in potential serious injury.
Brownells is continually communicating with reputable, commercial
firearms manufacturers and suppliers to keep our customers
informed of future developments in this matter. To the best of our
knowledge, no special safety precautions have yet been issued for
the conversion of fixed breech bolt action, falling block and lever
action rifles or revolvers in good, serviceable, safe condition.
However, you must use caution in being sure the action is in
excellent mechanical condition, made recently and the metal of
sound manufacture.
Please read and understand the following safety notice presented
here by permission of ATK. At this time, Brownells cannot
recommend or suggest a safe and proven procedure for modifying
any .22LR semi-automatic bolt for operation with .17 Mach 2
ammunition. As in all situations involving modification to the factory
original gun, Brownells, its agents, officers and employees accept
no responsibility for the results obtained by persons using such
data and disclaim all liability for any consequential injuries or
damages.
