This stock is specifically made for the M40A3 rifle, and, as such, anticipates the use of the Remington 700 SA, and DD Ross Company internal magazine trigger guard, and has no cuts for front embedded rails for laser range finders. It is made to be 100% clone correct. This is a special order item from McMillan, and Charlie's brings to you direct from the manufacturer. The A4 stock is on the McMillan website for a little less money, but is a painted exterior. This product has the color throughout the resin, which was a Marine requirement. I guess, so that when the stock is scratched, the color remains, and is not a white scratch. While the stocks ships to you in olive green, you will see pictures in the wild with operators who have rattle canned the stock, barrel, optic and suppressor with tan and black and many other colors.
All service M40A3s are based upon the A4 tactical rifle stock, a match grade fiberglass rifle stock made by McMillan and cast molded in an OD Green color. The action is glass bedded into the stock with aluminum pillars, while the barrel is allowed to "float" (it is attached only to the action). The stock has adjustable length-of-pull (through a buttstock spacer system) and a Marine specified adjustable saddle-type cheek piece, which McMillan now only provides to customers asking for the military clone correct model, here, which Charlie's provides. The stock also has six mount flush cups, two on each side front and back and one on each on the front and rear underside. One bipod stud is located on the underside of the foreend.
In the service life of the M40A3, the rifle began with the DD Ross bottom metal and then changed to Badger. The DD Ross bottom metal, also called trigger guard, housed an internal magazine with a trap door at the bottom. Some might call this model the M40A3 Mod 0. Not sure, but that would make sense. The Marine Corps actually did not change the official designation when the trigger guard changed. Some might argue, and be also correct, that the M40A5 first started with the Badger trigger guard and no forward rail. So, the configuration with the Badger trigger guard and detachable magazine might also called the M40A5 Mod 0. We have heard it both ways. Dan Ross (DD Ross Co.) swears that the M40A3 all had his trigger guards, and McMillan tells us that the M40A3 had both.
What is important for you, the customer, to understand is that this model will only accept the DD Ross trigger guard and internal magazine.

Assembling an M40 rifle requires specialized skill from a gunsmith. Charlie's does not offer gunsmithing services to assemble your rifle, but ask our knowledgeable team members about the parts you might need, including the scope, mount for the scope and even a suppressor. Charlie's either has, or will have all the parts, and if you have not picked out a gunsmith, we can probably point you to a few that do great work.
The United States Marine Corps has had an M40 sniper rifle since the 1960s, so the devotion to military clone enthusiast is extremely high. Development of the A3 version began in 1996, and concluded in 2001. The M40A3 Sniper Rifle served as the primary sniper rifle of the US Marines from 2001 through about 2009 when it began to be replaced by the M40A5, and later the M40A6 and the Mk13 Mod7. USMC MARSOC and Scout Snipers carried the M40A3 in every clime and place, throughout the Global War on Terror and in other hot spots around the globe.
The M40A3 is based upon a McMillan A4 stock, with OD green color deep throughout the resin, and a Remington 700 Short Action, generally trued by 2112 Marine Corps armorers, often at Quantico. The bottom metal began as the DD Ross steel bottom metal and trigger guard, and in 2007, Badger M5 began to replace the heavier DD Ross setup. DD Ross also built the top rail for the scope mount with 30 MOA of cant.
Barrels have typically been Schneider stainless 610 24" barrels with a 1:12 twist and 6 grooves. Schneider makes an M40 profile barrel which tapers gently to less than 1" at the muzzle end, and has a straight run for the chamber and a few inches beyond. Unlike the successor M40A5, the M40A3 rifle barrel did not have a muzzle device, but a match grade crowned muzzle. The M30A3 was not designed to be used with a suppressor.
The scope is the S&B 3-12x50 with a GenII Mildot reticle, held by Badger Ordnance specific steel rings with 34mm tube diameter, and an extra large front ring with six screws. The bipod is the Harris BPMS 6-9", which is found on a myriad of US military sniper rifles.
The M40A3 is a bolt-action 7.62mmx51mm sniper rifle used by United States Marine Corp, including Scout Snipers and MARSOC.
The M40A3 is based around the design of the Remington model 700. It features a heavy floating barrel and is typically used with 175 gr. M118LR ammunition.
If you wish to add a PGW front laser platform, you should buy the M40A5 stock, but build your rifle and barrel to A3 standards.

Note to Buyer: We are selling this as it comes new from McMillan, in the box, made to M40A5 spec. What this means is that the inletting is done to spec, but with the expecation that some small adjustments for fit for the metal parts is quite normal. There could be a small variation in cut that require the skill of a craftsman to fit this as a rifle. It should not be a DIY project, but it could be. Be aware of what you are buying and it is not a fit the legos together and rock and role situation. You also should expect that major interfaces like the screw holes and pillars are in the correct position. We will not take back as defective small scratches (this is a military stock) or imperfections in fit of bottom metal, etc.
