Best base out there if u have the $ for it. - NightForce Remington 700 One-Piece Bases

I've got 4 of these NF Extreme Duty 20 MOA bases on my rifles with 4 sets of NF Ultralite Rings. These bases are made true and I've yet to need to bed 1. I have 1 on my custom 6.5x47 Lapua rifle and my gunsmith said it set perfectly after the bolt holes were drilled and retapped to 8-32 instead of original 6-40. I'm a machinist and have used special equipment at work that read degrees and angles and all mine have been at least 20 MOA. Great thing with NF is they make 0, 10, 20, 30, & 40 MOA bases for the main types of actions used for precision shooting. I've shot all 4 of my rifles with them on it out to 600yrds minimum and up to 1,150yrds. They have never let me down and despite a few getting bumped around have stayed true and also the finish still looks great lol.
