I find it funny that some will hammer the BAT receivers but will then say the Nesika and Pheonix receivers are great. All are built to teh same tightness, in fact the Pheonix receivers will be very little different then the original Nesikas, after all, Glenn was the original owner of Nesika.
I have never had a problem with BAT or Nesika receivers in the field and I have used them for years. I do however clean the rifles if they get dusty. I do not put a $4000 rifle in the mud and I tend to not let them get overly dirty, even if its a Rem 700.
Where I hunt, generally its not terribly wet but it can be dusty. Usually to **** cold to be wet!!! If my rifles get dirty in the field, they get cleaned that night weither I go home or spend the night in the field. Again, I have never had a problem with receiver performance.
To my knowledge, the Pheonix receivers for the Lapua are not ready yet. AT least Glenn contacted me and asked if I was interested in testing some of his receivers. I asked for the Lapua receiver and he said they were not ready, that was late this summer and he expected them spring of this year to be ready.
As far as the Surgeon XL receiver. ITs a good one but it has two major issues that I do not care for, well, three really. 1. Its HUGE for what it does!!! 2. IT has a VERY short OAL mag box, 3.600". 3. Its Chrome Moly, not hardly weather proof.
Stiller receivers. Pretty good. I would not class them in the same quality as a BAT or Nesika or Borden but they are very good for what they cost. I have seen a few that were not as square as I would like to see but on average, they are pretty good and you can hardly argue with the cost.
The M7500 Lawton can be made with a Lapua bolt face, I had one and it worked very well but Barney had to modify it personally as its not designed for the Lapua as far as the extractor goes. Now since Barney has passed away, I do not know if they will still do that.
As far as the Nesika Model M goes, I can not recommend them either. Not because of anything to do with the receiver, but because of a serious problem with customer service. Something very bad is happening at Nesika finanically so I would not recommend ordering a receiver from them. I will not order any more which is very sad to say.
My list as far as my opinion as to which is the best quality and weather proof.
BAT Model HRPIC
Stiller Predator X
Stiller 338TAC
If Borden would come out with a Lapua class receiver, it would be on the top of my list because of its great quality, price and function.
