What is the best accessory/ accessories you've added?

One of the cheapest things Is I bought a sheet of this stuff and took off my PVC insulation , It looks better and works better
enough to do two Crickets and screw up a few times for 15 dollars,,,,
This stuff is way cool... It really makes a difference when you put it on your LDC, I did on my 22 cricket, But my 25 had a Neil Carbon fiber LDC just to pretty to cover up.
I have it installed on my barrels , Even my dog noticed how much it suppressed the noise,,,,
