Actually I think the 1-6 magnification range is optimal for LPVOs. With such a small objective lens exit pupil size becomes a major restriction at magnifications beyond 6x. Also the lack of parallax adjustment somewhat diminishes the practicality of higher magnification especially at long range.
That said a 1-6 scope can take a good shooter out to 600 yards or so on a man size target and I personally can reliably ring the steel plates with my 1-6 scoped, 16" AR-15 at the 385 yard line.
The issues of wide magnification range LPVOs are further exacerbated in budget optics. You can get good, serviceable 1-4 and 1-6 scopes pretty far down 8n the price range but f9r a 1-10 that isn't a murky, distorted mess at max magnification you gotta spend some serious coin, 1k or more. Also with a 1-6 a second focal plane reticle is suitable which brings certain advantages such as better, brighter illumination whereas with 1-8s and 1-10s a first focal plane reticle is better. That generally means dimmer illumination and reticles that aren't always optimized for use at either magnification extreme.
For precision work at longer range there are some still relatively compact and lightweight 2-10x scopes that avoid all the limitations born of the compromises that LPVOs must make.
