If it was designed for the 70 like they say it should fit the 795.
But since I have no first hand knowledge of the stock I can not say for sure.
The only things I can think of is maybe the trigger guard would not fit 100% I know older marlin magazine fed rifles had a 2 part guard (But I think they used the same guard channel size). They also lacked the Bolt Hold Open lever (Which shouldn't be a problem as it should just go thru the hole in the stock cut for the magazine well)
So the best I can do is say "should fit". The last ones where beautiful and a great value and option. I doubt they there will be much more of these available. Order one and tell us how it goes!
The above is not legal advice. It is just something you read from some dude on the internet. It does not reflect the opinion of Calguns.net. If it seems rude it was probably meant to read sarcastically.
