Each brand and type of ammunition can produce different accuracy results. It
is best to try as many brands and types of ammunition as possible to determine
which performs best in your firearm.
DISASSEMBLY
Rotate the safety selector lever fully to the “ON” (SAFE) position. Remove
the magazine and visually and physically check the chamber and receiver
to be certain the firearm is unloaded before disassembling the firearm.
Wear eye protection during disassembly and cleaning.
Depress the large upper portion of the bolt catch to close the action. Use a non-
marring punch to push out the takedown and pivot pins (Figs. 17 & 18). (Detents
will keep the pins from falling out of the receiver.)
