I have not seen one in a while. They are one of those small items like the safety detent ball that are easily, (and conveniently, depending on your mood) lost.

Never seen one of those...but it sure would come in handy for tuning purposes...

Start with the 18 and factory tp size. See what you get and adjust tp size as required.

Since I prefer the 18 inch barrel for looks I suppose u r right that I should install it and detune if its too fast and tune it up if its still not closer to 495 fps....I wish I had that little washer Doc sharptail mentioned....that would probably do the trick if the fps is too high....I may not NEED to reem out the port sleeve after all....just might need that port sleeve washer....or reasonable facsimile....hmmmm

If you wish to incorporate the eighteen inch barrel why not just use a port restrictor ?

Sorry about that Pelsby....I like to give credit where credit is due.....you were the first to mention the port restrictor....thanks...I'll look for a few for future tuning...They'll come in handy..... :D

Look inside old tape players and vcrs for a source of thin washers of the diameter and hole sizes .

They're also a great source of small screws, nuts and bolts that can be difficult to source.

Hobby shops that sell RC cars, planes, etc. have all kinds of tiny, thin washers of various sizes in aluminum, steel, hard plastic, etc.
