putting aside the fact that a shroud sure does fancy up the ole s1k, I've noticed improved accuracy in my shots. (Maybe less than Photo22 has
) Then again you'd be surprised the tricks your mind will play on you.
Harmonics wise:shroud to an air rifle vs the sleeve/shroud to a Ruger 10/22, there is no comparison. But if you put all the little things you can do to improve whatever you doing better, it adds up in the long run.
End result I, personally, did not see a huge difference by adding the shroud alone. Tune kit, trigger insert, shroud (thx rich)and adding faom and weight to the stock(thx photo) sure did make the s1k a whole new gun, also my buddy's think I have one hell of a air rifle!
