| Re: Polishing internals only good for certain guns?
Ok, I'll TRY to keep my responses here short.
There's so many variables in this type of pneumatic system that I may not be taking them all into consideration. Now, the main benefit in polishing the receiver halves is to allow the hammer to move more smoothly and consistently. This means it doesn't get hung up more or less between shots, making velocity irregularities. A by-product of this is that it can move easier and faster. Since most people report velocity increases after polishing, I'm inclined to say they are indeed releasing more air. However here we must part ways to describe different after-effects.
If you're one of those that had to bring down your velocity after polishing, and you did so with an FVA alone, then yes, chances are you're using more air than necessary, but you've probably got a well fed cyclone and/or RT. If you're in this group, you may get a tad more efficiency by getting an RVA or spring kit.
If you're one of the above people but you used a regulator or RVA to bring down the velocity, then you probably ended up saving a little air each shot.
If you're someone that had velocity increased to a more usable level, then you were just happy for that.
Why so many different categories? Because A-5's are not exactly precision made. The parts are mostly cast instead of milled and the tolerances are higher than some other markers. That means that not all valves and powertubes will flow as well as others. Also, since you have varying barrel lengths and paints used, you'll have varying results there.
