posted on November 23, 2020

McMillan Fiberglass Stocks is known for making precision-driven custom stocks, and now the company is expanding its lineup of ready-to-install fiberglass stocks with the new Z-10 Bag Rider stock. 

The Z-10 Bag Rider stock is based on the company's popular A-10 tactical stock. The Z-10 replaces the A-10's familiar butt hook with a swept butt profile to more easily accommodate rear bags for bench or prone shooting.

The Z-10 Bag Rider is part of the McMillan Z-series line and features a universal inlet design which fits most Remington and Remington clone barreled actions and accepts a wide range of barrel contours. Actions that fit the stock include models from APA, Defiance, Bighorn, Stiller, Lone Peak, Surgeon, Ultimatum, and more. The universal inletting makes the Z-10 Bag Rider drop-in-ready direct, right from the factory.
