Marble's rear rifle sight
The quality you would expect from Marble's. I had tried to purchase a replacement sight from Ruger/Marlin but the man I talked to refused to sell me an original Marlin Sight even though the 336 is now in production. Ruger/Marlin does not intend to support all those millions of "legacy 94s, 95s, & 336s" Marlin Firearms.

Rear dovetail sight
This sight was purchased to replace the "buckhorn sight" on a Henry lever action 22 LR. The dovetail on this sight was a very tight fit and difficult to drift into place. This sight was a big improvement over the original Henry sight, both in target clarity and how the sight looked good on the rifle. Steve
