im currently in the process of modding my nerf guns but i have come to a difficult decision: 9/16" brass or 17/32" brass? im not sure which one would suit me better, im hoping to mod all of my nerf guns with one or the other so i dont have many different types of bullets lying around. any advice would be greatly appreciated.

Well this choice all depends on what fits your darts. 9/16th brass has a larger ID then 17/32ndth's brass. If your darts fit CPVC use 17/3ndth's because they have the same ID but if your darts fit PETG then use 9/16th's.

Clean up the grammar please. And search for the answer to a question next time.

17/32" is smaller than 9/16", which means a tighter fit on the darts. Springers need a tight fit, and air guns need a looser fit. Both sizes are going to be the same difficulty to find. You also have the option of OMC Petg, which is right in the middle of 17/32" and 9/16" brass in terms of inside diameter, making it a good median for having the same type of barrels on different kinds of blasters. It's significantly cheaper, easier to find, more durable, yet slightly less useful in that you can't telescope more than a 17/32" piece into it.

There are two routes that work best: 1) different size barrels for different blasters. I.e. 9/16" on air guns, and 17/32" on springers. 2) Telescoping brass barrels. Search around.

This is all dependent on the foam of course though. That's a whole other story.

Ok thanks. I also have another question. Does 9/16" brass fit in 1/2" SCH40 PVC or SCH80? I read somewhere that 17/32" fits well in SCH80 PVC but i was unsure about the 9/16".

9/16" is loose in schedule 40, I don't know about schedule 80 though.

Alright since we're talking about barrel fittings, what is the "Polyester" on McMaster-Carr like? Is it more like CPVC, 17/32, 9/16 or in-between?
