an expansion chamber is an expansion chamber aka the bigger the better
it was on a mongoose or something like that
it expands the gas, doesnt leak, gets cold(i like that)
it is very very scary shape
it is a working expansion chamber. it is a pretty big size so it expands gas well. it must have given the person some more shots. ok i think the shape is a little aquird looking. the grooves in the top look sort of confusing and it might make it difficult to hold. it also looks like something that an insane guy like jefferey donner would have
it is an expansion chamber. if you like the look and price buy it. if not get something else. i give it a 9 because nothings perfect.
