What is bigtime use? Do few thousands pellets fall n that category? Though I dd not face that problem but even if that problem is there, I don't think changing easily available o-rings is a big problem.

So please bear in mind that such parts, wigid or attachment needs to be serviced, cleaned or replaced over a period of time to ensure both efficiency & effectiveness....

1) After fow hundred shots , the objective lens get loose.
2) After every 60-70 shots ,one need to zero again.
If one buys such cheap scope , to make it working properly , one need to do following.
Just on arrival , use araldite on the periphery on the objective lens so the it sticks well with body of the scope. One needs to be very careful so that araldite does not touch the main part of lens and let it cure for 24 hours.
Turret is the big issue for cheap scopes ,with every shot it tend to unscrew itself and thus loosing zeroing.
In ordes to stop that ,one can take out the tunnet screw along with the spring. This spring can be replaced by harder spring or the spring can be pulled to increase its length so that when compressed , it retains more recoil power
This will stop the habitual unscrewing of tunnet.

Hi Basu da,
I just wanted to know if 3-7*28 Bushnell scope can be adjusted for 20 Ft range. I own one and find the grouping to be higher. Although elevation screw has been unscrewed to maximum.
