In addition to the trigger guard assembly, you'll also need the magazine well liner, rear guard screw, and possiibly the magazine latch plunger and spring. Available in blue mostly, but if you have one of the bright stainless rifles, you can order the VBZ (gray finish) stainless parts. A few minutes with a buffer (go very lightly) and the gray finish is gone. Parts will then perfectly match the bright stainless.
