Still chasing the correct front sight for my BL-22.
From my calculations, I needed a .570" high front to go with my Skinner peep.
I ordered one (Marbles) from Skinner and got it yesterday.
Today I took 3 of my .22 rifles out to shoot.
The Nylon 66 looks huge here, it's not, just the other two are so small.
All have 20" barrels ( well the 66 has a 19.5" barrel).

When I sold the first BL-22 I had in the 80's, I though it nice but a bit too small and light to hold steady. In 2012 I bought a FLD Octagon BL-22, but was pretty disappointed in the accuracy of it, so it went down the road.
Now that I'm older, this BL seems just right, not too small or overly light.
My 9422 feels big and heavy, and the Mountie feels like it weighs a ton !
Well, I zeroed the BL then shot a couple 50 yard targets with RWS HV HP.
First was a bit right so I adjust windage, and shot another group:

Groups are a bit high and the Skinner is all the way down, so it looks like I'm going to need a .580" sight.
I don't think marbles makes one taller than .570", so I might have to get that fat .600"Skinner brass blade. Oh well, I'll get it right eventually.
Putting the fastFire dot back on might happen. I like a peep but a front sight that's almost 3/4" tall looks pretty goofy.
