Recrowning my NAA MiniI have enjoyed shooting my NAA mini mag and Sidewinder. However, the mini mag has consistently shot low and to sometimes to the left off the POA (point of aim):
So I took a closer look at the crown of the muzzle:
As you can see, there is little in the way of factory polish or refinishing (although I didn't take a pic of my Sidewinder's muzzle, it has a bit better polish).
So, taking the advice of other Internet cheapskate gun owners, I popped down to the local Homeless Despot to purchase the highly expensive recrowning toolkit in the hardware section, which contains 6 #8 -32 x 1 in machine screws in brass:
I already had a small kit of Porter Cable's cleaning and polishing compound:
Next, I chucked the recrowning bit into my variable-speed electric drill, heavily applied some #1 compound, then while holding my mini, let the weight of the drill press against the muzzle while the drill rotated the rounded head of the machine screw - all while moving the drill in a circular motion to evenly apply the compound. After a few applications, I moved onto #2 compound, then #3, then finished with #5:
The next day I headed to the range and shot the same ammo at the same distance using the same grip and support (my small range bag):
As you can see, I pulled one flyer. The first five rounds were vertically in-line from below to the target. The next five were close in. I'm pretty pleased and hope to enjoy a tad better accuracy now when practicing!
