Yes, velocity is under control, and the overhop has also been tamed.
The issue of the velocity being too high was easily resolved once I realized my G39 was one of the "Canada only" models, meaning it had been modified at the factory to shoot over 470 fps, in order to meet Canadian importation standards.
I tamed the velocity by fully closing the NPAS valve and by dropping in a small rubber O-ring between the valve and the two prongs on the back half of the bolt (looking at a disassembled bolt, that'll make clearer sense).
It's easy to know what size of O-ring to use - it's the same size as WE uses in the BB loaders they ship with their guns.
My G39 now fires .28s at about 280 fps, comfortably under local field limits. Since the rifle has all the range I need, and good accuracy. I'm leaving it set where it currently is. If I feel need for more velocity, I'll simply open the NPAS valve half a turn.
The overhop was solved by installing a Shredder nub and an RA-Tech bucking.
The latest issue I'm tackling is using my G39 without pre-adding lubricant to the propane. I've found the Airsoft Innovations lube I've been using is just making a royal mess inside the weapon, and I'm not convinced additional lube is even Beneficial. As long as proper gun lube is added where needed, I don't feel the propane needs to be doctored. I'll let you know how testing goes...
This is what I'm using now:
"
The Ultimate Synthetic Grease That Slicks Up & Protects A Lot More Than Just Triggers; Smooth, Friction-Free Operation For All Types Of Firearms
If you have a firearm that "works", then you need Action Lube Plus. Not a petroleum-based grease, but a synthetic-based, semi-solid lubricant developed and used by military special forces to protect expensive, hi-tech firearms and equipment in all temperatures and all environments; from the deserts of Kuwait to the Bering Strait. Actually exceeds the mil spec of standard, molybdenum disulfide grease. Action Lube Plus lubricates and inhibits corrosion and galling from salt water, powder residue, sweat and moisture on all types of metal, including stainless steel, titanium and aluminum. Action Lube Plus is very concentrated; only a small amount applied to the face of sears and triggers will dramatically decrease pull weight as well as smooth actual trigger feel. On high friction points like bolt raceways and lever mechanisms, just a dab of Action Lube Plus completely eliminates wear and helps assure reliable functioning. A very light coating on the outside of your guns will keep fingerprints neutralized and protect expensive bluing from rust and moisture damage that can occur during storage."
