I have the a10 but shot the raptor with and without the reflex. Both shot on a 20in bolt gun .308. The Raptor had a slightly better tone and maybe a touch quieter but I didn’t really notice a difference with the reflux. I went with the a10 since it was quite a bit cheaper (demo can) and the price difference for the raptor didn’t make sense to me. Both cans are very quiet. Not crazy about the “looks” but slap a cover on and you are good to go.
