The adjustable stock jack
is a tender subject on NES.
I have no idea how slick a job that is.
After you've applied your patented crypto-pin technique,
is it at least still obvious under magnification that the frob is pinned?
Or if the gun is grabbed for evidence,
is there a risk that
The Boys Down In Metallurgy
are gonna twist the barrel into a pretzel
trying to torque the compensator off
because they're convinced it's not pinned?
If it's totally invisible, maybe tart it up with a
pin decal.
By weak analogy with those Danger Jet Intake decals they put on fighter planes.
Once again you have crystallized my very thoughts.
