Thanks. I never used a scope, in all my years of shooting, until I got my first PCP rifle. I have a bit of a passion for iron sights myself and I am most comfortable with them.
I'll have to get cracking on the set screw solution when I have a moment. I'll probably lose the filet on the bottom to provide extra opposing force when tightening (so it doesn't tip the unit forward).
I've also found that the front sight takes black spray paint really well and perfectly matches the finish of the rest of the gun after a few very light coats. I've been resisting the temptation to buy more PLA. I'm out of black, but I have more of the other colors than I can use before it goes bad.
