16) Changing the barrel
The barrel and receiver are one piece and are changed as a unit. The
bolt assembly is universal and will fit any SR 30, except the magnum
bolt will not fit a standard caliber SR 30, and standard caliber bolt will
not fit a magnum caliber.
Warning: Never attempt to interchange the bolt assemblies between
magnum caliber and standard caliber under any circumstances.
Caliber change is easily accomplished by the user in a few minutes
using the following steps.
• Remove bolt and magazine from rifle
• Loosen the two internal wrenching captive screws in the trigger
guard assembly.
• Carefully remove barrel and receiver assembly from stock.
Note: After screws are completely free of the receiver, place the rifle
on a table, with the muzzle and the bottom of the recoil pad on the
table top. With the palm of the hand push down on the top of the
receiver where it joins the barrel until the forward recoil lug is free of
the stock. This is a tight fit, and for this reason a second barrel assembly
should be ordered with the rifle so the factory can ensure a perfect
fit of both barrel assemblies.
• Install desired caliber barrel assembly in stock.
• Tighten internal wrenching screws, reinstall bolt and proper
magazine.
