McMillan Fiberglass Stocks



The birth of the modern tactical rifle can be traced back to the year 1975. Gale McMillan, founder of McMillan Fiberglass Stocks, partnered with the Marine Corps to develop a pioneering project that is now known as the M40A1. Today, McMillan is the most-issued tactical stock in the world. Army, Navy, Marines, Secret Service, Treasury, Border Patrol, FBI, and so on... our customer list reads like a who's who of the best professional tactical units in the business.

The McMillan tactical series are a combination of benchrest accuracy, battlefield ruggedness, superior ergonomics and specialized design. There is indeed a difference between professional equipment and look-alike equipment. When that difference matters to your job performance, demand McMillan.


The A-3 is the most widely used field sniper stock available.

The forend design provides a more stable platform while shooting off sand bags or a pedestal and makes an excellent tactical stock. The A-3 is made primarily for Remington and Winchester actions and it will take barrels up to 1.350 inches in diameter. Available in right and left hand.

Stocky's® take:. The original tactical stock, the McMillan Fiberglass Stock, is the standard by which everything in this country and about 33 others are judged. The hand lay-up fiberglass (carbon fiber is optional) is battle tested and unquestionably able to handle any and all conditions they may be used under. For those desiring the finest composite stock with uncompromising attention to detail and quality, there are few real choices, a McMillan would be on the top of the heap.

Great Stock-Great ServiceReview by Woodrow
I ordered this stock last year for a 6.5 creedmoor I'm currently building. As of now I still have the 22-250 barrel. Its amazing how much this has helped in accuracy. The look and feel of the stock is amazing. Thanks Stockys for delivering on time and answering the questions I had. Next year I am planning on starting a build on a hunting rifle and I will be sure to purchase from Stockys again. Thanks! (Posted on 2/4/2018)
