I disassembled my CMP used Daisy 853C today and was following steps in a set of online videos. At one point the narrator showed a small flatish square of material that he called the "barrel stabilizer." It was fit between the barrel and the piston housing. Supposedly it reduces barrel movement and improves accuracy. I could not find this part on the parts diagram in the 853(C) manual. Is anyone familiar with this part? Is it still available? Is the lack of the part likely to affect accuracy?

I think I know the part you are referring to; that small black plastic square about the size of a fingernail.
I always thought it would be pretty easy to slip out during disassembly & get sidetracked.

First thing is I'd call Daisy - the last time I talked with one of their techs re: my 853, they were definitely helpful & knowledgeable.
Which is why I've been sweating when (not if) they'll eliminate that department.

If I needed to fabricate a substitute, I would clip out a piece of neoprene or something ?

I called Daisy today to place an order for some other parts, and the lady I spoke with wasn't familiar with the part. I offered to send her a picture (which I did) and she is going to forward it to one of their gunsmiths (or is it airsmith?)

Here's the answer I got from Daisy regarding the part in question. My customer service rep sent me this quote from the Daisy Quality Manager:

"That part does not belong on the Model 853. You wont find it on the 853 drawing. That part was available on similar models. Some people like to use them across the board to take up slack in older guns. There's no harm in that. "

That might explain why some people find them in their rifle and others don't. Prior owners might have added one or not. I guess I'll get one now that I know the part number (132084-000) supplied by a helpful member of the GTA Airgun forum.

Thanks for the comments.

Thank you to Kestrel4k who pointed me here from a similar thread on the CMP Forum...

That Daisy Quality Manager must be a young'un...they were part of the 753's and 853's from at least the mid 90's when I first had to start resealing these guns. Daisy must have lost some institutional knowledge over the years. The Quality Manager I've dealt with is Anthony S and while he is great at what he does and knowledgeable...he is a young'un!!

I'm not sure they do a whole lot functionally. I'm guessing they were there to keep the barrel band from pulling the barrel into contact with the frame. I coach at a High School Air Rifle program, and have had these guns apart literally hundreds of times and most times, those spacers have little to no pressure exerted on them. If I were determined to replace that spacer and didn't have access to the genuine part, I'd probably put a dab of hot glue there to approximate the spacer (hot glue would probably work better as it would stay in place versus that spacer that slides around and falls out the first chance it gets as you disassemble the gun.
If I swept the floor I'd probably turn up at least a handful of those spacers.

The part is not on the current diagram or parts list for the 853C. I only knew about it after seeing a video posted online that showed the disassembly/reassembly of the 853. And, in agreement with you comments about there being "little or not pressure exerted on it" and "that spacer that slides around and falls out at the first chance it gets," the video mentions that the part will move back and forth along the barrel when in place. The video also mentions that it easily falls out when you disassemble the rifle. Have you ever known the part to fit snugly? Has there been a slight change in the surrounding parts that make the part superfluous now?
