Excellent base, but I had to use the mill to get the magazine well adapter to fit.

This company has a big pair of nuts when It comes to machine work. Not to mention they accept gift cards (most companies don’t) which makes buying more anonymously a breeze my wife won’t be able to see what I spend money on . The only thing is sometimes the payment has to be submitted several times so that it goes through
