How To Clean Your Kwa Ib, Hop Up, And Bucking

However I seem to be having problems installing my hop up bucking after cleaning. I installed an edgi 6.01 barrel on my M4A1 during the cleaning process but am having issues sliding the barrel and hop up bucking back into the hop up unit. The bucking seems to be a tight fit and stretches as I push it in, leaving a small amount sticking out. I'm wondering if it would be ok to use a little bottled silicon oil on the outside of the bucking to help it slide back into the hop up unit, being careful to stay away from the top side where the nub makes contract... Would the oil soak into the rubber and eventually saturate it, making it ineffective?
One other issue, when I back the hop up all the way off while the barrel is out I can see the hop up is still on and had to use a qtip to lift it before removing the bucking. Should the hop up dial show an instant change or does it require a few a shots to be moved to my desired setting. I'm just worried something is sticking in the hop up unit.
Thanks for any help :-)

Lastly, the nub may keep the bucking slightly engaged sometimes when the hop-up is dialed off. The test is if you are getting too much hop when firing BB's with the hop-up off. If that is the case, then the nub may be too long.

I ordered the barrel from the pro shop and was careful to specify the "K" designated option, however I don't know how to verify which one was sent to me since there are no markings on the tube it came in and the invoice didn't show the full part number. I just have to trust the order was shipped properly from the pro shop.
Time to take another crack at it.

Brand new owner of a M4A1 and of course I had to clean it with silcone spray before I played, read that somewhere.
Went to the field and had no hop up to speak of. Since reading this I pulled the barrel and hop up and cleaned everything with soap and water. Still have to test it out but from what I've read here I'm sure that the silicone I added plus any packing grease was the issue. I'll update when I can get out to the field to test, don't have the room in my backyard.

- What BB's are you using?
- What mags are you using?
- Have you done any modifications at all to the gun? This includes the addition of furniture like a new flash suppressor
- Is the cylinder head cracked or damaged? This can cause the bb's to fire all over the place

sorry for not being clear, yes when i fire on semi-auto the BB's shoot only about 10 feet 80% of the time, otherwise they shoot normal. on full-auto the problem is less prominent but it is still occurring. i am using Ultrasonic .20g BB's, are these okay? i have ordered .25 KSC BB's but they have not arrived yet. i am using the Stock KWA mag so i shouldn't have a problem there, i also purchased two D-Boys Hi-Cap mags and i don't think there bad either. as i said i have just recently (as of two weeks ago) got this gun, so i havent modified it in any way. i have only used it twice in skirmishes so no hard wear n' tear should have occurred. Without taking the gearbox apart i see no cracking on the cylinder either. i have heard that this is a common problem with new KWA guns and will eventually go away as you break in the gun? i don't know if this is true or not.

Now, here are a few things to look for and try:
- As discussed, try KWA BB's
- Be sure the mag release button and latch are secure
- Look at the feed ramp to see if there is any damage. Look at the bottom in the magwell and at the top buy the nozzle. If it is damaged or not seated properly it can cause feeding issues
- Open the receiver and see if the nozzle cycles when dry fired...if it doesn't then it's the tappet plate
- With the receiver opened, see if the nozzle will move side to side...if it does then the cylinder head may be cracked.
Please keep us updated. We will figure it out.
