[QUOTE="Damascus, post: 949210, member: 57878"] I use Nightforce 20 MOA bases exclusively on all my 700 short action builds - and I've yet to encounter a problem. And also, they ARE available from NF with 8/40 screws instead of the 6/48 version. I have personally used one on a .338 Lapua rifle with only lowly 6/48 screws, even carrying a heavy 34mm scope on top, and never shifted a bit! I personally think that is due to the internal recoil lug. I would prefer if NF would use full "bars" going across the top rather than having that "lightening" cut going down the center (just like the Badger Ordnance bases), to give more purchase when you but the ring up against a lug for installation - but again, I've not had any problems with scopes being out of alignment windage-wise. I've had one action that I had the scope optically centered, but needed almost 3 mils of left adjustment to zero at 100 yards - which is unacceptable to me, but upon inspection I found that the problem didn't lie with the NF base or ultralight rings, but the base holes were drilled slightly off center from the factory (the furthest one forward). I was able to loosen the base and move it slightly to the right to correct this - the base's holes were just large enough to allow enough movement to correct for out of spec receivers (to an extent). I then bedded the base to the action with some Brownell's Steel Bed, and the rifle has remained flawless to this day. As for Murphy bases, I have yet to use one personally, so I won't comment there.
