i think the problem here is the OP thinks that hiting 450fps is going to give him a range advantage over the rest of the guns running 400. lets just put it out there for him that fps doesnt really have a huge effect on range. Fps will allow u to use a heavier bb effectively, a heavier bb will carry energy out to a further range, but if yer hop up camt provide enough lift for the heavy bb its useless to you. Between 350-450 fps you will get about the se effective range but with a 350fps gun youll he using .25-.28g bbs, with 400 .28-.32 and with 450 .30-.36 (if yer hop can lift a .36) a well tuned 400fps gun can prety near range my 500fps bolt action. Runinng 450fps now yer hit with a minimum engagement distance (probably 100feet or so depending.on host/field rules) suddenly you need a good sidearm for engagements within 100feet, keeping in mind that im most cases airsoft engagements are goining to be in the 50-150foot range. I personally would shoot for the 400fps mark (as alot of fields arent going to let u run 450 on an aeg, most guys who do are guys who are certified snipers trusted to play safely with a high powered gun, epecially.one that is capeable of a high volume of fire) hit
400 fps, nice and consistant, good inner, good hop up, good bb's and a low zoom optic (1.5x or 3x or variable starting at one of those) dial it all in and you should be able to reach out beyond the range of most other guns on the field, unless there are a bunch of ptw's in yer area then just get certified and build a bolt action if u want range on those lol
