Essentially. It's an air stripper when its primary purpose is to strip the muzzle blast in the interests of accuracy, a muzzle brake when its primary purpose is to reduce recoil.
Is the bore size consistent with the barrel bore?
Not quite sure what you mean there.
If you're asking if the "bore" of the air stripper is around the calibre, pretty much. It's a little bigger, but as close as is feasible.

Porting alone might suffice (it's shown good results for me in the past), but while I could settle for "just suffice", I'd sooner have overkill than underkill - each projectile I'm sending downrange is going to be pretty costly in both time and money, so I'd rather not waste that with being needlessly measly.
After all, why just use porting when for little extra effort I can combine that with an air stripper, and get the benefits of both?

I won't lie, it's not going to be soon. This a long term project that demands a whole load of resources - space, time, effort and money.
While most of the "paper" side of design is done or close to complete leaving the practical stages (first preliminary testing, then after that's taken into account, the actual "range day"), it would be stupid to move on to those (and their expense) without things like the venue already sorted.
As I'm sure you can appreciate, places where one can safely and discretely send high velocity AP darts flying a quarter mile are not entirely easy to come by. When I've got a confirmed site, then I'll start looking at spending the time/money on what will probably largely boil down to a one-off "long range day".
(I suppose if the UKSGC meet ever gets together, that'd be a possible time for all of that to happen.)
Still, without my laptop, the design is on hold anyway - not to mention, I've got other things on my timetable for a while anyway.
