That's great info above, I have 2 AA Jackals which are identical except the one has a longer shroud going down the barrel, Its not broken or refinished but seem to be different for some reason, I sold the combat which was a SA variant, The thing was loud and quite hard to cock, In all fairness I've only taken the one out in the summer days and the AA jackal is a very accurate gun, I was quite surprised how well it grouped.
