Echo 1 Stag-15 M4 Rang and accuracy upgrades

[Noriego]

Im looking to increase the range and accuracy on my Stag-15 M4. Ive read around and seen I need to upgrade the hop up unit the piston head, cylinder head, and the nozzle. Im not quite sure because i havent really upgraded any gearbox parts before persay so kinda new would appreciate any help i could get thanks!

fastest and cheapest way to upgrade range and accuracy: 6.03mm inner barrel from stock barrel will increase both fps (range) and accuracy (groupings). If you want to increase range and accuracy further without messing with the gearbox, you can also get a madbull ultimate hop up unit, although some people give mixed reviews ever since i added them to my primary weapons, it just blew everything else i used away, my groupings were tight and bbs went exactly where i wanted them to go. Also the madbull ultimate is a single hop unit so if you got a 2 piece hopup it wont work unless you know how to convert it to a single yourself, but cheapest way is get a nice tight inner barrel.

Barrel, bucking, and heavier BBs, that's it. Those other things are air seal problems, if your air seal is ok, don't try to fix it.

I would suggest a 6.01 tightbore, use quality BBs and you will not have an issue. Buckings, I have had success with madbull, but do some research. BBs, you should use .25s if your fps is over 350. If you are close to 400, you might even try .28s.
