Nice set. I am returning it because I need the 4x. Order screen defaults to the 2x and I must not have caught it.

So happy I found this kit. I am renovating a vintage airstream and couldn’t seem to find this gun with adjustable air pressure so as not to damage the aluminum skins. Out of stock everywhere. Tried a few rivets with it and it works great! Solid set. Thank you Aircraft Spruce.

I was pleasantly surprised how nice this gun is. It has a very smooth action and is very easy to regulate from a tap, tap, tap to a full on barrage. The case is also a nice plus.

I was tempted to penalize one star because it took two months for rivet gun order to be delivered . . . but thats not fair to the product itself. I am totally pleased with the 2x rivet gun. It is very well made and easy to use. The kit came with everything I need. It produces outstanding results. As far as the product goes, I couldnt be happier.

Q: What do the 2X, 3X, and 4X refer to in the drop down menu for these rivet gun kits?

That is in reference to the power of the gun, and recommended max diameter of the rivet that can be bucked. 2X is up to 1/8" diameter, 3X up to 3/16", and 4X up to 1/4". A regulator is commonly used to lower a larger powered gun to buck smaller diameter rivets.

Q: How big of an air compressor do I need? My tank is only a few gallons.

You should be find just using a few gallons worth in a tank. It doesn't take much to power this rivet gun.
