LIMITED WARRANTY CONT
'
Smith & Wesson's Lifetime Service Policy begins after the war-
ranty period has expired. Smith & Wesson will repair, without
charge, for the lifetime of the original owner, any Smith &
Wesson handgun purchased on or after February 1, 1989, and
any M&P15 series rifle, that is found to have a defect in material
or workmanship. Eligibility for this Lifetime Service Policy
requires returning the Product Registration Card within 30 days
of purchase. The Lifetime Service Policy covers functional
defects; it does not include the firearm's finish, grips, magazines
or sights. The Lifetime Service Policy is in addition to and not an
extension of the Smith & Wesson Warranty.
This warranty gives you specific legal rights. You may also have
other rights that vary from State to State.
