in theory it could possibly help - original idea was to remove possiblity of air rushing past pellet and upsetting flight. Years ago i used a don nygord product on my match pistol- yes it helped, reduced muzzel flip to almost nothing. As that was a co2 pistol you could on certain days see the gas being diverted from behind the pellet. Yes air pitols due have a bit of muzzel flip, particularly when you are tryng to nail that dot at 10meters one handed. Later on all the top match pistols went to ported barrels. My fwb 40 (pcp) ( ported barrel) is perfectly dead in my hand when firing. Velocity is only around 500+-600 fps ( rule limit vel.). With the more or less standard pellet shape apx 900 fps (about best velocity wise), i think the edm approch on the rifle barrel will likely work well. There is a lot less of a vibration issue in air units vs rf with main issue being how the vavle is being opened. I am no expert in air br but have been around it since the early days and shot my share of targets with units from air arms, anshultz, walther and a usft. Saving my pennies for an airtex or baur compressor. My old converted miltary unit is still running, but mr. Sheldon has retired from the biz so support for that unit is questionable.
