What is it with putting a shroud on barrels .
Have you not heard LESS IS MORE.
the less crap you have interfearing with your gun the less you have to fuss about and mess with your head .
Strip back float your barrel see how it shoots may need to tune the barrel I set the harmonics with a adjustable air stripper a bit of a faff but worth it.
Make a gun shoot with the min of clutter it will only mess with your head
