After running several different PTWs I have seen a slight increase in distance with a longer barrel. The Carbine out shoots the CQB, and the M16 out shoots both; but only by ten to twenty feet or so. I did notice a better accuracy as well at range. This was true with all tests. I've seen different effects with AEGs, springers, and GBBRs. Hop-up and airseal always play the biggest role in BB stability. Then it's BB weight and velocity, then barrel bore and length. You won't get the same effects with every gun, but there are some guidelines to follow.
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
