First off, let me say dealing with Neil was a pure joy. If anyone is in the market for a high quality air stripper, this is the guy.
I actually shipped my Max out to him so he could give it a once over and get a better feel for what he could do for the Speed/Max guys. He confirmed what others were saying: the bulk of the noise is mechanical. That said, he engineered an LDC that slips a few inches over the barrel and screws into the internal baffle system. This allows similar performance to a longer tube but keeps the overall length of the bullpup down and manageable.
Plus it looks completely bad ***.
I wish I could get that scope down a bit more, but my previous medium height rings made it impossible to get a sight picture. I may play with that some more but it's an awesome package right now.
I'm going to try out some SPL apps on my phone to get some before/after decibel readings. Just firing it in my basement the abatement is very noticeable.

Do you think it'd be easy/worth the hassle of getting longer rod(s) and bending them around the air guage and stock screw to completely avoid both? I was also thinking of cutting the screw and fabricating an eyelet for the rod to pass through.
Yeah, probably not worth the hassle...but it's a pretty dumb design from the factory.
is get a chainsaw file and file the threads off the screw that holds the stock,..file away untill smooth in the middle section of the screw, the trigger linckage now will be much more straigt and will rub smooth,...the trigger will improve considerably, you'll feel an incredible difference

Using my poor-man's lathe (cordless drill and rasp), I turned down the screw quite a bit. I think i need to increase the width of the "channel" for lack of the proper term. It feels like it's catching a little on the top (screw head) end.
Maybe even trying to put a little kink in the linkage, but I'd be SOL if something broke there.
I'll report back on that this afternoon. I had hoped to use my iPhone and "Decibel Meter Pro", but forgot that the iPhone mic is only good to about 110 dB. My initial "stripped" shot was 107 dB and the normal shot was 109, which was obviously wrong since the LDC was much quieter.
A meter will report the loudest sound so if you have quietened the report, something you would notice, the meter will still read the highest sound which could be mechanical. I made an LDC for a Pneuma that was quieter than the action of cocking the gun, I found this out by not activating the DB meter until after the gun was cocked. You might try what I did and wrap the gun in something to help deaden the mechanical noise and try the DB reading again. We may end up trying something for the gun later as we had discussed, but for now I am too busy to bust out the sewing machine, lol. Keep up with the reports, it is the only way I can tell how my efforts are working, or not?, All the best, Neil.
