SPOILER!!!!! AND I'M NOT KIDDING!
Note that early in HFQ some 5000 M96 rifles were captured by a Desnairan privateer. We weren't told if the same ship carried ammunition for the M96s as well, but if it did, then Desnair can certainly send samples of the new rifle, its magazines, and its bullets to the Temple. So the CoGA may have examples of this bit of cutting edge Charisian tech already.
However, in my opinion the M96 and brass bullet cartridges are the first bit of technology that the CoGA simply cannot duplicate in sufficient quantity to make the espionage worthwhile. The barrel of the M96 is specially hardened steel with extra deep rifling, and the church simply can't make that quality of steel. (Or it couldn't until the Charisian engineer was murdered and his briefcase was stolen in LaMA.) The bullets require several major technological steps that the Church simply cannot duplicate - certainly not in any useful numbers.
So the CoGA's generals will know the sort of rifle that's killing off their soldiers, but they won't receive similar weapons and ammo before the war is over.
END OF SPOILER
I'm reminded of a similar situation in the Island in the Sea Of Time series. Nantucket had designed and started building rifles that used brass cartridges, fully expecting that spies from the other side would steal the design for duplication.
They had actually HOPED the other side would attempt to duplicate the design in every particular, because the other side's production capabilities was so much more primitive that if they attempted to try to mass produce brass cartridges, they'd hopelessly cripple their own industry.
I can see a similar situation arising for the Church when faced with the same situation.
