Cleaning: JB & Kroil are a great combo - try easy solutions first.
Savage Law Enforement Series are excellent. Some w breaks & others are threaded to add your own. Even Percision Carbine.
Kimber also makes a law Enforement rifle.
I have Bell & Carlson stock - was made for Sako Mountain Rifle - gunsmith glass bedded it and opened up the barrel channel - I added a much heavier barrel than original intent.
I love it. Much stiffer than my Hogue but it cost more as well so it's not a good comparison.
Hogue was $56 for Mini 14.
