I have a standard 15 22 with holographic sight and am having a blast including good accuracy with this set up. I just got a nikon rimfire 3x9x40 ballistic reticle scope and nikon 1 piece mount. wife wants to get another rifle rather than switch out these two sight systems on the same rifle. should we spend the additional $200 for a performance center gun for the scoped rifle or get another standard mp15 22 for scoping? Would the performance center gun with its supposedly better barrell and trigger and the above scope give significantly better accuracy($200) worth?
