By best out of the box do you mean range and accuracy, reliability, functionality? What? Nothing out of the box is usually perfect and as long as your hop-up does its job barrel length had close to no effect. If you want a good brand of gun right out of the box get a VFC, they have a few DMR-ish models. If you're looking for overall performance out of the box with a DMR look and feel, then if recommend an RA-Tech Level III M14 EBR or a Systema M16 Final Evo or later (so you don't immediately need the hop mod). But then prepare to spend in upwards of $1,700 - $2,000. VFCs start at around $500 or so.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
