I know. I have owned quite a few Pre 64 Model 70s and they all had great triggers.
I just purchased an switched out to a mcarbo trigger spring couple weeks ago for my m70. Was already using another aftermarket spring from ernie the gunsmith and i much prefer the mcarbo. I still had to massage the trigger with a dagger file to get a 2 3/4 to 3 lbs break, better than the 4 or 4 1/2 lbs
It was the target trigger spring, i had been using it for the past 8 years or so. Either of the outfits springs is a vast improvement over the factory spring for me. I noticed little to no creep with mcarbo and the ernie spring had just a small amount of take up before breaking over. As i mentioned tho, i still had to touch up the trigger with a file to get where i wanted.I looked at ernie the gunsmith's page and there were a number of different springs depending on what trigger weight you wanted. Which spring did you get from him?
The trigger on my first SPR was the best trigger I'd ever felt until I got a PBR that had one that can be safely set to a slightly lighter pull weight. Same type of trigger. That PBR I got here has been great.
Just bang the epoxy off, turn to the weight you like, verify it's safe by dropping on the buttpad, and shove your glue of choice all over it. I use a 5 minute epoxy.

Probably keep the nuts from moving.What is the epoxy for?
My SPR a1 trigger is excellent, definitely under that 3 pound mark and no creep. I didn’t realize they unsafe under that 3 pound mark. I may have to buy a Mcarbo spring and install it.The main reason for using the Mcarbo spring is because the M70 trigger isn't safe under about 3lbs. I'd have to measure it but I think I have it around 1.5lb with the Mcarbo spring and it is drop safe.
If you can cock your rifle, empty chamber obviously, and hit the butt stock on the ground relatively hard, and it doesn’t fire, I wouldn’t worry too much about it.My SPR a1 trigger is excellent, definitely under that 3 pound mark and no creep.

I will give that a try. The trigger right now is one of the better triggers I have. It’s right up there with my trigger techs.If you can cock your rifle, empty chamber obviously, and hit the butt stock on the ground relatively hard, and it doesn’t fire, I wouldn’t worry too much about it.
Well did the test you said to do and my rifle failed it. I guess I will be ordering a Mcarbo spring and readjust the trigger.If you can cock your rifle, empty chamber obviously, and hit the butt stock on the ground relatively hard, and it doesn’t fire, I wouldn’t worry too much about it.
This. I am considering one cause I want AICS mag compatibility.I have had no luck finding a left-over CDI bottom metal for FN/Win short action.
Has anyone tried the PT&G "wide mouth" bottom metal using standard AICS magazines??
How does the gen 1 fn spr with hs precision stock compare to the later generation? Was it accurized like the later gen? Is it generally considered to be as good of a shooter as the later gen?
I put the M*Carbo spring in my A3G and got it down to 1.5 lb. Did the drop test about 30 times, including a couple times where I was worried I would hurt the rifle from hitting the buttstock against the ground so hard. It never went off. Zero issues.So regarding the recent trigger weight and drop test conversations, I put my Lyman (I know, not the best) digital pull gauge on my three SPRs just now.
First Gen - 3lb,15.8oz average. I've never messed with this trigger. The rifle shoots great, so I've never messed with anything aside from skim bedding the action into the stock.
A1 - 2lb, 5.2oz average. That worried me because I've just read all these posts about that being potentially unsafe. So I cocked it again and dropped it six times onto the recoil pad from about a foot off of my concrete floor. No issues.
A2 - 2lb, 6.8oz average. Did the same drop test, and passed.
I took my A1 and A2 triggers apart a while ago and polished the crap out of the contact surfaces with Mother's mag and aluminum polish on the head of a q-tip. Took probably 30 minutes to do each. Then I backed the two nuts off close to as far as they'd go and that was it.
I checked both at the time for safety. My little routine is cycling the bolt 10 times, then cycling the safety 10 times, then smacking the reassembled rifle off my knee 10 times again. If it passes that, then I'm content. If it doesn't, then I correct the issue.
At this point I'm of the opinion you can get the SPR trigger a touch under 2.5lbs and still be safe...but I don't think you could get it down to 2.

We had this conversation 15 years ago on shooting forums. Some guns will be safe at 2.5lb and some will fail at 4lb. There is a lot of tolerance in the factory parts. I'm of the opinion that if you adjust the trigger at all you should change the spring. Sounds like your three are fine but it could have easily gone the other way.
I’d compare the width of the rail to other rails and see how it stacks up before doing anything.Has anyone had a problem with rings not clamping on the factory rail tight enough? I have my g2 razor in vortex pmr rings and when I torque the screws the rings will still move slightly. I’ve tried several other sets I have and no problem with them. my g2 razor has been on my match rifle for a while with no problem. R700 with the aluminum nightforce 20moa rail.
How does it compare to this?It is supposed to be factory mil1913 20moa
I've been running the ptg bottom metal with aics mags and it's been 100% even in matches. It's not my favorite design but we don't really have many choices since cdi is no more.How do you like the PT&G? Any issues? What mags you run?
I am about 99% going to get one if it's a reliable as the FN stock mag.
IMO, many old style triggers are going to be unsafe below 3lbs. The sear surfaces are just too ”wobbly” out where they are at, especially at lighter weights. I’ve always wondered why someone doesn’t recut the action and fit and oversized trigger and sear.…..maybe with improved geometry! ….or maybe make it narrow and sell a shim kit with it?? Seems like you could get a decent 2lb consistent pull.Adjustments on the FN/M70 are very easy , it is just a matter of two set nuts on the set screw to your preference. I started by the least amount possible to what I was comfortable with and tested safety by bumping the rifle butt against the floor until I was satisfied with pull and safety of function. Both of my rifles are set at between 2.5&3 pounds of pull and are safe under normal use with the factory spring, I hope this helps and don't be afraid of experimenting with the factory trigger. If you feel the factory spring is not for you Mcarbo makes springs I'm told!
I just found a new old stock SPR A1, now begins the scope acquisition process, I believe I will keep this one to less
that 16X.
Thinking of the S&B PM 10X mil-dot.
Technically it did not become a thing until they bought Winchester Repeating Arms. So Technically it is an FN "metric" Winchester Model 70. Probably the finest Winchester Model 70 built up to that point before they stopped making them in the USA. As I understand it none of the parts interchange with the Win M70 made previously. FN has always made fantastic CHF barrels. For mass-production and military and law enforcement nothing beats a well made CHF barrel.
I kick myself in the ass routinely for not buying one while I could!
I hear the Winchester M70's now made in Portugal are also fantastic!
Not a lot of USA made FN SPR's were made and sold and people and agencies that own them tend to hang onto them!
The few examples that have passed through my hands while not as pretty as my 2001 Hi Grade M70 with Extra Fancy Turkish Walnut and super deep polished bluing had all the hallmarks of a precision manufactured rifle with excellent quality control!
I am not a fan boy though for any one brand or model if someone makes a really well made rifle that is accurate and durable I like it!
Apparently at least $2K
Might also want to check out the Leupold MK5 3.6-18 with the new pr1 reticle. I have one and they are fantastic optics. No problem using out to 1200+. You can find them around $1500.I would get an ATACR 4-16
