Home Forums Hunting & Shooting Custom Rifles & Wildcats Winchester 670/670a build

Anyone build off a Winchester 670/670a? Can get them for pretty reasonable price and I thought they would make a cool custom. 280 ai or something with a #2 barrel and a bansner stock in a blind mag configuration. Everything compatable with the model 70? Gun show this weekend and I want to keep my eye open for a cheap one.

Let me know what you think or if you’ve messed with one.

A new/used remington action can be had for 300.00 roughly and the large availability of good after market parts for it would negate any savings at that point in my opinion

I agree. I have had many guns built on Remington actions. Just think a m70/670 would be something different.

i have heard but dont know for sure that some of the barrels for the lesser priced models are pressed in and not threaded .......might be something to verify before buying

That would be a good thing to know...I’ll have to do some digging

Mine is not.

my stupidity ....i was thinking this was the winchester version of the 770 remington....

Ok good. I was finding a few customs built on 670 actions.

No reason not to build on a 670, there is a lot to like about M70's - good hunting trigger, the sliding extractor works well, easy take down of the bolt assembly and a good safety, and IMO they are a good looking action.

I will probably get a lot of kickback from this statement but I have had better luck with model 70's shooting good out of the box than I have had with Rem 700's shooting well out of the box.

If you find one be sure to shoot it before rebarreling - you may be surprised.

Found a 670 with three position safety. G prefix serial number, I think it a newer one. It’s a 30-06, got it for $300 shipped. I think it’ll make a good 280ai.

Plan on replacing the magazine spring and follower ( they were riveted together and fail at inopportune times). I'm another one that says find a 700 action or use a M70. MB

The 670 IS a M70 - just the cheaper version...

Don't shoot the donor! If there is a chance you'll sell the build at some point you will probably take a bit of a beating on the price by using a 670, fwiw. I think they are a great value, but not one to put a bunch of money into.

Redneck I know but they are damn rough compared to an XTR. MB

It might need to take a little trip to hangout with redneck. I just need to decide on a caliber.

So if I do a bansner(legendary arms works) stock it comes as a featherweight contour. What barrel contour from pac nor would fit in the stock best. I’ll probably have to open up the shank area but the barrel channel is like to leave as is. (I don’t want a barrel any heavier than a featherweight)

I have two 670 Winchesters that I used as a foundation for builds. Both were chambered for the 30-06 round. Built the first one as a 6.5 x 5 Swede. I was able to get a Winchester produced barrel from Gun Parts. It is a featherweight barrel. I think it is 22 inches long. It shoots 120 grain Partition bullets very well. 140 grain bullets still go into groups 1 -1 1/2 inches for three rounds. When the barrel gets hot the groups start to grow. My other rifle is now a 280 AI. I put a 26 inch, magnum weight Wilson barrel on it. It really likes 160 - 168 grain bullets. I can made a baseball dance across the range at 300 yards with it on a regular bases. I have been thinking about finding another one to build on. The action is to the Model 70 as the 700 Remington ADL is to the 700 BDL; Blind magazine.

Only difference ive seen in the 670's Ive handled and M70's which ive owned over a dozen of:

Blind mag
Beech stock
No jeweling on the bolt.

You'll do just as well starting a blind mag custom as you would a M70 Ranger (same thing but jeweled bolt) but you'll start off 50-150 bucks ahead.

Many of the Rangers actually came with a featherweight contour barrel already installed, usually with sights screwed on. Just drop it in a better stock and go hunting.

Some of the 670 had a sliding two-position safety instead of the standard Winchester type.

The short action 670 calibers were built on long actions.

It has the 3 position m70 style safety. I’m going to shoot it to see how it does as is. Depending on barrel contour I’ll get a stock on it. If it shoots good I may just let it be for a while. I just don’t want to ream out the barrel channel of a new stock then want to put in a lighter contour barrel down the road.
