Reynold357 makes an excellent point, but I do have a counter point.
Yes there are about 5 million M700/M721/M722 Remingtons made and sold, mostly in the USA.
The Howa imported by Weatherby, Legacy, Smith and Wesson and all others probably don’t come to 1 million. So the numerical likelihood of having a Remington break and need repairs is higher.
That is all 100% true.
But let’s look at the Mausers.
In my 48 years as a gunsmith take a guess how many 93, 94 95, 96 and 98 Mausers in every variant combined I have had to repair due to a factory part breaking.
Take a guess.
Up until this January, only about 6 weeks ago, that number was exactly 0
None. Nada. Zip. Zilch. 10 less than 10.
Well in the 1st week of January I finally saw it. A man brought me in a M98 custom rifle in 25-06 that had a broken ejector spring. So the perfect record I had told people about for Mauser reliability was destroyed for me just a few weeks ago.
If we look at the Mausers made in all models from the 79 to the 98, according to both DeHass and Speer that number comes to about 60 million. Many have been repaired due to damage in war, as well as rust but if we look at those needing repair because of factory design and defective parts the percentage is so low as to be hard to calculate. I can only speak for myself as one man but as a gunsmith with 48 years of work behind me, I can say the M98 system was the best bolt action ever made for reliability.
Now let’s look at the M91 Mosin Nagant and its variants. Sources say no less than 77 million were made and some men say it is as high as 107 million.
Not as common in the USA as in other nations, but there still are a lot of them around, even here.
I have had to replace 2 broken extractors on M/N rifles. I know a smith in Reno that had to make a flat spring on one that broke in the follower arm. Those are the only three I personally know of that had need of repair from a factory part being broken. I am sure there are others around, but I only speak from my own knowledge base.
Now in my records that I can look over right here in my shop I find 47 Remington M700 I have dome major repairs on in just the last 7 years. And I make muzzleloaders for the most part. I have no store front. I do the smithing for 4 gun stores in central Wyoming, but I am not out looking for work on hunters and shooters guns. When I worked in Nevada I did work for 9 gunshops and one of them (In California) was a Remington Service Center. Replacement of broken extractors, re-solders of bolt handles and repair of triggers was common.
I have had to repair more M700s than every other bolt action from every other maker combined.
That would include Winchester, Weatherby, Savage, Browning, Howa, Ruger, Mossberg, Marlin, Steyr, Tikka <---(Often can’t be repaired because Tikka will not sell parts) Sako, Interarms, Kimber, Walther, Krako, BSA, CZ, Husqvarna, and all military surplus bolt action rifles combined.
I do not have complete records going back to 1968 but when I look at what I do have, these are the facts. Facts are just that, and facts can be misunderstood. But truth must be deduced from facts.
In this list I am speaking ONLY of parts failure due to metal fatigue, wear or design flaw. I am not speaking of damage that is not the fault of the firearm at all, but of the owner.
If I look at the guns I have had to fix because the owner did something wrong, (or failed to do things right) then I can say I have worked on M700/721/722 about as often as any other.
So I speak from a base of knowledge, not hear-say. I have my own conclusions. Others may conclude something different.
Remington's 700 is my 2nd to the last choice for my own use. Only Tikka rates lower with me, and that is because they will not stand behind their rifles at all. At least Remington has some customer service and will sell parts or replace parts. Tikka won't.
