I have MP-153. Unusual smoke comes out from under the forearm after first shot. When I field strip the gun to clean it, I find carbon caking on the magazine tube right beneath the point where barrel gas holes open.

Is it due to burning of lubricant? Any impact on the gun? Can I control it?

You are right . It is known as "Gas Cooking " you have too much oil in the the area where the gas port is, it gets very hot on firing and burns the oil next to it. Clean it thoroughly and if you still get the (Not Likely to happen ) then the weld on the gas port has a leak which can only be put right by a competent Gun smith like Akram at Baksh Illahi Lahore or Kareem in Karachi or the shot gun specialists at Dara Adam khel.
If it is a leaking gas port you must have it repaired or your gun is in danger of breaking apart with the barrel intact

@Skeeter, Dr Hanif Malik, Faisal Aziz, thank you for your valuable input.

@Sir Skeeter, the carbon caking (Gun cooking) is exactly below the gas holes. Even I can see the presence of carbon deposits in the shape of two dots. Is it safe to assume that there is no crack in the gas port?
Secondly, it is always the first shot which gives so much of smoke. What I have thought about it is that the first shot burns the lubricant present in the barrel as well, which is causing the carbon deposit. Rest of shots are normal. What's your opinion about it.

as u said 1st shot produce smoke else rest remains normal.
Thats clear evidance you keep ur gun almost wet with oil.
Clean the barrel so on mag tube with dry cotton cloth.
You won't see happening again.
A low quality cartridge can behave same fasion but as u stated rest remains normal so thats not a cause.

after cleaning and with the gun dry/without oil if there is no smoke then there is no problem.

bhaiyyya it is just burning lubricant released from the gas port
it is called carbon caking
clean the gun thoroughly with cotton cloth 4 excess oil
and inshallah u will not have the problem again

and the term internal combustion

is your gun an engine????????? :lol: :lol: :lol: :D :D :D

@Sir Skeeter, I have done what you told me. There was no such issue after I fired the gun with almost no oil in the proximity of gas ports and in the barrel.
