After testing several possibilities, they ordered 700 Remington Model 40x rifles (target/varmint version of the Model 700 bolt-action rifle), and gave them the M40 designation. Sometime in the early 1970s, the USMC armorers at MCB Quantico began rebuilding the original M40s into M40A1s.

The process involved, among other improvements, replacing the original wood stocks with McMillan A1 fiberglass stocks, as well as replacing the original Redfield scopes with Unertl scopes. The M40 was originally designed by Jack Cutty and Neill Goddard.

Army also uses the Remington 700/40x action as the basis for its M24 Sniper Weapon System. The primary difference between the Army and the USMC rifles is that while the USMC M40/A1/A3 utilizes the short action version of the Remington 700/40x (designed for shorter cartridges, such as .308 Winchester/7.62mm NATO, 7 mm/08 Remington, .243 Winchester), the Army M24 uses the long action version of the same rifle.This dayscope is mounted with Badger Ordnance USMC M40A3 34mm scope rings, which utilize a standard ring in the rear and a wider MAX-50 ring in front. The standard front ring cap is replaced with a SPA-Defense B634 34mm Male Dovetail, as a mounting platform for the Simrad KN200 Night Vision Weapon Sight.
