Upgrade Question

Sterling Archer

Hi all i'm looking to upgrade my M4 i want to up the fps and accuracy, i know to change to a tight bore barrel, but from there it all gets fuzzy :D

DeBurca

What is your current FPS and up the FPS to what ?????????
As for the accuracy a change of hop-up rubber + the Tight Bore Barrel you mentioned already

Sterling Archer

Current checked saturday was 250 with 0.2s i think can't remember exactly, and what ever i can get out of her

DeBurca

Has it always shot at 250 or is this a resent drop off in FPS

Sterling Archer

Think it's dropped slightly, first time i payed proper attention to the crono but seems like it's dropped might have been 258 fps actually

DeBurca

Well if we assume that when new it was 300ish then you either have an air leak some where or the piston O-ring is worn

Sterling Archer

Cheers we'll assume the worst, both :pac:, it's a G&G Gr16 by the way , just means i'll have to go looking for those parts so.

DeBurca

Well if it is the O-ring you could fit a new piston head complete with O-ring and a Bearing for a tenner and while you are fitting it maybe apply a bit of PTFE tape to the cylinder head also
Plus if fitting that tight bore barrel you where talking about a new hop-up rubber will improve the airseal and the accuracy aswell

Sterling Archer

Cheers man, i'll look into gettin parts and getting it done, the barrel i could do, the hop up rubber probably but after that i'd end up with "spare parts"

DeBurca

If you normally go to LAC you could probably get all the parts from Tony and his magic van

Sterling Archer

Cheers man, Now to the magic van, might look at a whole new hop up unit maybe.

DeBurca

There is no need for a new hop-up unit unless your existing unit is broken or damaged the standard G&G unit is good
A new rubber in the standard unit is perfect, G&G parts are good as is
