McMillan M88

The History of McMillan

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 BMG long-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 M88 Rifle Review

The M88 is an anti-materiel bolt-action rifle, characterized by a single-shot mechanism and a long, thick barrel complemented by a large muzzle brake. The rifle was produced from the late 1980s until the 1990s. The action operates on a 90-degree bolt handle with a rotating bolt locking mechanism using dual front locking lugs.

Early versions came with holes for mounting purposes and a basic polymer thumbhole stock; however, adjustments have been made in late production models, including an adjustable stock, Picatinny rails, and a smaller multi-baffle muzzle brake. The M88 is a single-shot weapon and is chambered for the .50 BMG round. However, certain versions of the weapon introduced later in the production, were available with detachable box magazines, capable of holding 5 rounds.

The two-position safety lever is positioned on the right upper side of the receiver and is easily reachable with a thumb. The M88's barrel length is 737 mm, featuring 12 grooves with a right-hand twist. Additionally, a bipod can be attached to the front of the M88's forearm. Previously identified as the M87, the McMillan M88 has a history of use by special forces. Despite its service record, information about the M88 remains relatively scarce. Even McMillan's official website offers limited details about this particular model.

There are two terms found for similar thing: quick release scope mounts and quick detach scope mounts. Term quick release scope mounts is used mostly in Europe and quick detach scope mounts is used mainly in USA, although they mean the same thing. With these terms we describe a scope mount that can be quickly removed from the rifle in the field without using any tools and quickly attached back on the rifle when needed.

Main advantages:

possibility to use multiple scopes on the rifle,
easy transportation of the scope and the rifle separately,
if scope fails, it is possible to immediately detach it and use iron sights.

FIXED vs DETACHABLE scope mounts

Fixed scope mounts are mounted to the rifle with screws and sometimes even with glue. This means that it is impossible to attach or detach the scope mount using bare hands without using tools. It also means that they are not meant for constantly being attached on or detached off the rifle. Once you screw the mount on the rifle, it normally stays there for a longer period of use.

Detachable scope mounts offer possibility to attach or detach them without using any tools. This is extremely handy while transporting the rifle and the scope separately and it also offers multiple solutions of different optics on the same rifle. Detachable scope mounts can be attached or detached from the rifle in a matter of seconds, using bare hands.

DETACHABLE vs REPEATABLE scope mounts

It is important to know and understand expressions “detachable” and “repeatable” while talking about scope mounts. Term detachable scope mounts implies scope mounts that can be quickly attached or detached without using any tools. However, when you detach this kind of mount and attach it back on the rifle, it is recommended to zero the rifle before using it again. Procedure of detaching and again attaching the mount will probably need a sighting in before next shooting, because mount will not be secured on the rifle in the perfectly same position and conditions as it was before detaching it off the rifle.

On the contrary, repeatable scope mounts are most sophisticated mounts. These scope mounts are also detachable, however – they provide removing scope from the rifle and attaching it back again without zeroing the rifle every time. This means that they are made more precisely and that they are offering a possibility of using different optical sights / scope on the same rifle. These mounts are ideal for hunters who can use optical and iron sights interchangeably, depending on the needs in different situations. With the repeatable scope mounts, it is useful to keep them oiled as well as the upper part of the rifle, so that repeatability is more ensured. With a touch of oil, the repeatability might be better, because parts of the mount will always return to their previous locations.

Different types of repeatable scope mounts:

Pivot mounts,
Dentler mounts,
Picatinny repeatable mounts,
12 mm dovetail repeatable mounts (for break barrel rifles, such as Steyr Duett, Blaser B750, Fair Combi, Fair SLX 800, Bettinsoli rifles, etc.),
Original repeatable mounts, made by manufacturers of rifles for their rifles (Blaser mount, Sauer SUM mount, Mauser M03 mount, Steyr Monoblock mount, etc.).

TIP OFF / ROLL OFF vs SLIDE ON mounts

Nowadays, there are a whole lot of different possibilities, made for attaching riflescopes on the rifles. There are also a lot of different expressions, having the same meaning. It is good to know that tip off and roll off mounts are basically the same thing. They represent quick release scope mounts for dovetails and rails which can be rolled or tipped off the rail vertically to the side of the rail. On the contrary, there are also slide on mounts available on the market. They represent quick release scope mounts that can be slided on or off the rail or dovetail from front or rear side of the rail / dovetail. All of these expressions are mainly used for separate rings that can be attached to the rails / dovetails. As far as functioning the rifle, it does not matter which one of these mounts you choose – tip / roll off or slide on mounts. If they are installed correctly, they are all going to work. However, the main difference between them is the principle of attaching them on rails on dovetails.
