The story of McMillan Firearms began in the late 1960s when Gale McMillan, the grandfather of Ryan McMillan, invented the fiberglass stock. This innovative manufacturing process for rifle stocks learned during Gale's time at Motorola is still utilized in the industry after more than 50 years. Recognizing the potential for improvement in this area, Ryan McMillan, Gale's grandson, started Grayboe company in 2016 with a clear mission in mind - to make the production of top-notch, epoxy-based rifle stocks quicker and more cost-effective. This was an idea that had been buzzing around since the days of McMillan Fiberglass Stocks. Tapping into the rich McMillan family heritage, Grayboe rolled up its sleeves and dove headfirst into thorough research and development. Today, Grayboe is a strong contender in the rifle stock market, continuing to uphold the McMillan family name.
McMillan Gunworks, however, was founded by Gale McMillan in the late 1970s and has been a well-known name in precision rifle manufacturing, particularly for military and law enforcement applications. Ryan McMillan then co-founded McMillan Firearms in 2007 to carry on the legacy. The company, based in Phoenix, Arizona, made a name for itself with its remarkable line of firearms, particularly the McMillan Tac-50, a .50 BMGlong-range anti-materiel and sniper rifle. Other products include the McMillan Tac-338, Tac-300, Tac-308 sniper rifles, and the ALIAS Rifle System.
In 2013, McMillan Firearms was sold to Strategic Armory Corps, a move that significantly expanded its hunting and tactical division. Strategic Armory Corps was founded in 2011 with a focus on customer-centric design and structure. After acquiring McMillan Firearms, it was able to leverage a broad range of technology and experience, resulting in improved product development, customer service, and commitment to manufacturing quality products.
Presently, McMillan Firearms continues to offer a comprehensive range of premium hunting rifles under the Custom Collection, as well as the TAC and ALIAS series, offering innovative designs in various configurations.
McMillan G30 SA Rifle Review
The McMillan G30 SA is a bolt action rifle featuring a custom G30 action base on the design of Remington 700 and made from steel. The action is CNC precision machined, with general tolerances held to 0.13 mm, while critical components are machined to 0.013 mm. The bolt is made from hardened steel and has spiral grooves for smooth operation in hostile environments. The rifle is structurally identical to the LA models but is only available in two short-action calibers.
The G30 actions, although developed by McMillan, are based on the design of the Remington 700 and are available in two action lengths: short action and long action. This implies that one-piece, as well as two-piece scope mounts suitable for Remington 700 LA and SA, will be interchangeable with McMillan G30 SA and LA actions. On this landing page, the short action version of the action is introduced.
The bolt lugs are hand-lapped to the receiver, ensuring equal force and square contact, and the extractor is a large Sako-style claw, also designed by McMillan. Moreover, the G30 employs dual ejectors: a Remington-type plunger and a secondary spring-loaded mechanical ejector. Most rifles come with a removable five-round box magazine, which is housed in a Badger Ordnance triggerhousing, however, some versions are available with the hinged floorplate. The safety mechanism comes in a form of a two-position lever, placed on the upper right side of the receiver behind the bolt handle and follows a simple back (safe) and forward (fire) operation. The bolt release lever is positioned on the opposite, left side of the receiver.
The trigger mechanism is reminiscent of Remington and can be adjusted for the weight of the pull.
Stocks are either made from a polymer material or wood, with the A3-5 type, offering adjustability for cheek rest height and length of pull. All models feature a rubber recoil pad at the rear end of the stock.

McMillan G30 SA Calibers
The rifle is available in the following variants:
.243 Win.
.308 Win.
McMillan G30 SA comes with four holes on the top of the receiver which can be used for scope mounting purposes. There are two holes in the front and two on the back end of the receiver. Since the action is based on Remington 700 receiver, one-piece, as well as two-piece scope mounts suitable for Remington 700 SA will be interchangeable with McMillan G30 SA actions.
Unfortunately, we were unable to find the picture of the McMillan G30 SA receiver, therefore the receiver of Remington 700 SA is used below for demonstration purposes. Note that hole spacings and radiuses are the same between the two rifles. Should you happen to own McMillan G30 SA and would be willing to send us some photos of the bare mounting surface (no mounts installed), we kindly ask you to contact us at info@optics-trade.eu
