No offense but do you know how old that is and how hard and fast Ruger dropped it!
You might as well be looking for Sten Sub Gun optic and laser mounts! LOL
I am not even a ruger Tang Mounted Saftey Hater aka TMSA member. LOL
I always thought it was rough I could not find much after market support for my Ruger M77 Mkii VT that I have owned since 1994-ish. Cricketts for decades! Hard to find anyone that will blue print them as well. All kinds of half truths about them as well.
I am going to let you in on a secret I learned it after about 30+ years of purchasing fantastic rifles that where not Remington 700 or Savage 110. If it is a fantastic design, well made and accurate out of the box and not a Remington 700 or Savage 110 after market support is almost non-exscentint. It has gotten better slowly the past 5-10 years. When I got a Ruger American the first 5 years no one made anything for them. It is still lean but now you can get some after market support.
Howa is under represented. That said the garbage can Remington 700 which at best is only marginaly better than the dumpster fire Savage 110 has always been well supported. You can not swing a dead cat with out hitting something made for the Remington 700. Even to this day a lot of custom actions are designed to fit the external diemensions of a R700 so that all of the stocks for a R700 will fit. Often the contour is the same so scope bases fit and the fire control chain is designed to work with Remington style triggers!
That is not to say there is anything wrong witht he R700 action the design was designed to be cheap to manufacture compared to the Winchester Model 70 and Mauser 98 style of actions. It is a solid design but not a great design. It was excuted as poorly as a rifle can be executed in terms of how it was actual manufactured. It's real claim to fame was how easy they where to remachine to shoot very accurately and how many where churned out kind of like the General Motors Small Block Chevy not a great design or well built but built by the 10's of millions and cheap to purchase or trade a case of beer for a used one!
In the 1980's and 1990's I could build 3-4 high performance SBC V8's for the price of 1 high performance Asian or European inline 4 cylinder or 6 cylinder. I could order my parts from catalogs no problem where for Asian or European car's I had to trach down, write letter's, make international phone calls to track one part at a time often and they had to be hand made to order etc....
I learned a really good lesson "If you want to build custom or high performance and you cannot make all of the parts yourself than start with a platform or powertrain that has a lot of support already in the market place!". To many people go the other route and then are disapounted that they have head a dead end because there is not support for their pet project rifle!
So in the future before you purchase a rifle never assume that the market will provide! Always do your home work to see if chassis, synthetic stocks, wood stocks, 20,30,40 MOA scope bases are available, bottom metal is available etc.....
Bell & Carlson is likely the lightest you will find in a symthetic stock. I doubt anyone makes a trully light weight hollow carbon fiber stock for it!
