New RG4570B

[Ranch Dog]

When I got home I placed an order for a Williams peep sight (FP-336, supposed to be a near perfect fit), should make life a bit easier.

How about a report back on how the FP-336 fits. The Weaver 63B scope base used on the Marlins does not fit the RG series the threaded holes in the receiver are larger.

Here ya go...

The FP-336 fits with a couple of caveats. The screws that came with it were too large, but luckily I had some 6-48 x 1/8 oval head in the parts cabinet. Perfect size and the oval head self-centers the sight in the mount holes.

The second issue is the contours of the receiver. The bevel on either side of the Marlin 336 are apparently quite a bit more pronounced than on the RG4570. It keeps the elevation from bottoming out properly, but should not be an issue in the field. Won't know until I get it out to the range.

Thank you for posting the report and pictures! Let us hear how it shoots! What ammo are you going to work with?

Looking forward to a range report on this one... I've looked at Rossi's 45-70 a few times online.

Drifting the iron sights , to get a zero is just standard operating procedure for me . And filing down the front sight , if it shoots too low .

I have looking at these rifles , but so far , I have not been able to justify the $$$ .

New tires & some front end work on wifey's car has dried up my gun fund . :-(

Also thinking about a Rossi single shot .45-70 .

God bless
