Questions & Answers
Will this work on a a Savage 110 Precision with the factory MDT LSS chassis? Manufacturer Answer

Yes, it will. If you are using the same buttstock that comes with the Savage 110 Precision, you will need the Fixed to Fixed version.

After trying a few other folding adapters to add a folding arm brace to a PLR-16, I tried this one. Worked almost out of the box, but had to add two washers for spacing. Without the washers the screw would bottom out on the PLR-16 tube. Only real co...
