I normally for fun shooting .223 in 300m range for around 5" group with iron sight. and .177 at 10~15m less than 3' group and .22 is for fun at 25m range. With hop up and smooth bore BB tube! Yes this won't seriously egar to make us tunning the gun! Just standard see throgh bore quick sight adjustment around 15m (Xystema PTW and YYW M4 GBBR) is ok for us for running around wargame shooting live fig.11 and not UIT target paper. I also, de-act the YYE hop up and keep the BB hiting the floor for personal distance adjustment and don't want to waste time tunning sights. For all these year follow through handling of firearms are good enough for handling toyguns accurately in very short range.
The above is only my opinion!
