I met Roy personally, when I dropped off my bottom metal so he could do my 527-Lux, and he's a great guy. I had my bottom metal back in less than a week, and couldn't be happier.
The spot refinishing, he did, looks no different than the factory finish on the rest of my rifle.
I carry an extra 5-round mag with me, but could really care less about the lowered mag capacity - since my 527's a Hornet I use for "walk-around" varminting & woods loafing.
