BigTinBoat,
Welcome, and right on man! It's really cool to hear that I was a bit of help in your decision to try these PBs out!
Hopefully, you'll end up loving yours as much as I do mine! When they're set up the way you like them,
and shooting well, they're sooo much fun!
Hey, not only do I have a good answer for you, here's a photo to go along..
When I removed the shroud to directly connect my suppressors, I needed a way to 'suspend' the barrel..
My rimfire target guns have 'floating barrels', so, I sort of wanted to try to do the same thing..
Suppressor weight would cause barrel droop, so, to counter that, I added a rubber-grommet inside of the front band.
It works AWESOME!
The OD is just big enough to seat perfectly inside of the front band,
and the ID is just a bit small, so, there's a nice tight fit around the barrel..
Being soft rubber, it allows the barrel to 'float' nice and centered,
so there is no worries about it being pushed in any direction..
I got a DonnyFL "Extender" more or less as a joke - to put on my pistol,
but, in the end, it'll be fitted to my .25 cal Kral Nemesis..
For the first mock-up, I threw it on my PB, and took this pic:
Overkill? Psh.. There's no such thing! Hahaha
Okay, back to reality..
IF you'd like to get a factory/OEM front barrel band for the NON-Shrouded setup,
you can actually order them through Pyramid Air [I'll probably do this eventually]
They're called:
"Kral Barrel band (Axis Apparatus) for non shrouded rifles"
Here's the link to them:
