kwa shooting issues

[Red Devil]

I just got a kwa m4 last week and used it on Sundays game. The problem I am having is some  bb's go the distance but more than half of them move out only a few feet then drop like a lead ball what is the problem? It's a two piece hop-up.

bucking air seal/hopup/ dirty barrel. Iv just solved this exact problem on a sr12 and a sr10

lemme guess it shoots great on full auto, except for like the first 5 bb's.
and semi auto is a joke right

It's the opposite fulll auto is a joke. Semi at least puts some rounds down range.

Do you know how old the gun is?

first thing i would do is Make sure its all air tight. cilinder, cilinder head, nozzle and bucking to barrel seal. Seems like that could be the issue.

If its not that i would start looking at the air nozzle, cilinder head or tappet plate for wear. if it is an older gun that shit could wear out.

Then after checking all of that and it was all good, still shooting with same results, i'd replace the bucking make sure its not warn causing the problems.

Another one would be to check the hop up nub. Alot of people think you can just drop in a H nub and get a huge gain in accuracy from that.. sadly thats not how it works.. thats just going to cause it to eather jam, or tear the bucking.
causing simular problems to what you have.

try just lubing the hell out of the barrel with some silicone spray first and see if it still has same results

Also, be aware the 2GX bucking is VERY thin and tears VERY easily.

I am just going to probably take it to my gun tech who is on the team. I am not going to act like I know what you guys are  talking about. Thanks for all the info!

yep. and remember ur gunna be stuck with a kwa bucking, i have them in stock if you want one right now. right now.
you have to get a different barrel if you want to use other brand buckings on it, and sadly only PCT out of spokane, wa. Or EDGI has that type of barrel.

kwa has a way of dicking people to using only there parts.. lol
