So I bought an extreme air max one a couple of days ago, and I want to make a brass breech for it. I want to know if I use a 3/4" to 1/2" pvc reducer, will it be air tight with 9/16" brass pipe? Here is the reducer and here is the brass pipe if it makes a difference. As an inner barrel, I wanted to use this. Is this an effective barrel setup? Is there anything I'm doing wrong?
Thanks a lot,

Wow, don't place a McMaster order for a shitty BBAM1(BuzzBeeAirMax1)!

The BBAM1, 6, and 10 all have the reduced airtank of the Buzz Bee later generation Panthers; in fact the Air Max One is nothing more than a relaunch of the Panther.

To answer your question about how to make a slide breech the obvious answer is to find a guide on NerfHaven. Well, you haven't done that so I guess I'll just throw a few easy and cheap options at you.

1/2" PVC and 1/2" CPVC 'magic' breech. This one is simple, go to the hardware store and find the two foot pre-cut segments of both PVC and CPVC in half an inch. Find a nice slim segment of CPVC and take it over to the pile of PVC; spend a few minutes playing doctor until you find a segment of PVC that eagerly accepts the CPVC into it. Make a few cuts, do a bevel or two, and slap a 1/2" coupler onto the airtank.

If you can't find any 'magic' PVC just buy yourself some 1/2" CPVC and some 1/2" Thin Wall PVC and a little bit of craft foam. Line the internal of the thin wall PVC with the foam and supa glu it, a single layer is all you need. Make a few cuts, do a bevel or two, and slap a 1/2" coupler onto the airtank.

It should work. I THINK the OD is the same as the K&S branded stuff, you might want to double check to make sure they nest properly. As for the 1/2" pvc, generally it's a smidge loose. I generally have to run a piece of tape or two around the 9/16" brass, but it depends entirely on the pvc you're using. If you're doing what I think you might be doing, is this similar to your idea? Because if so, I can tell you it works very well, at least on springers. I'd be slightly concerned about using longer lengths of 17/32 on an air gun unless your darts are not too tight in it. Generally speaking you want a looser fit for air guns for your barrel.
