Riflespeed x CAT ODB - 300blk

CAT ODB is a low backpressure silencer. It’s so low that I had to go to a lower Riflespeed plunger! More below.
Took the super 🤫 300blk SBR to the range to test out RifleSpeed’s #907 plunger with the ODB. ODB wouldn’t cycle with plunger #917 which is the perfect plunger for the DDC Enticer S (setting 11 w/ subs).
ODB Ti on this 8” pistol length gas Wilson Combat 8” needs setting 12 on the RS AGB. I probably need to drop down to the #897 (believe the #887 is standard from Kyle for 300blk). The lower the number, the shorter the plunger, the more gas available at the same setting. RS is neat that way: quick fine tuned and repeatable adjustments within the bandwidth your weapon needs for supers or subs.
You may not be able to find a setting that runs subs unsuppressed all the way to supers without A LOT of gas with suppressed supers, but you just have to choose your use case. Personally, I don’t care about not being able to cycle unsuppressed subs bc I will never run them without a can. I have found that supers are maybe 6-8 settings lower than subs suppressed on the same plunger; so, if you can run subs at 10 and supers on 2, you have enough wiggle room for different environmental conditions.

What setting did you get LRBHO on?

I had to go up to 12 on the 907 plunger. I will probably swap it out and see what I need on the 897 plunger next range visit. Setting 11 on 907 got LRBHO sometimes but had some failures.
