Similarly, target penetration and lethality may require a larger calibre bullet, which may drive the weapon’s weight particularly for accurate automatic fire. Longer effective range typically means a longer barrel. On the other hand, these factors need to be balanced against weapon performance. A lighter weapon is easier to carry and less fatiguing for the infantryman, while a shorter length barrel can be quicker to handle in dense vegetation, close-quarters, and urban combat. Weapon Characteristicsįor an individual weapon, physical aspects such as weight, length, and ease of operation are important factors. ![]() This also offers an advantage when employing a bayonet which for many decades was a major combat consideration. Being lighter and more compact, carbines are easier to handle, but the rifle’s length and mass can provide a more stable platform. 30-06 M1 Grand of World War II and 1960s 7.62mm M14 used essentially the same size ammunition as their bolt action Great War predecessor the 1903 Springfield. The carbine’s shorter barrel offers less opportunity for propellent burn and less powerful cartridges which result in decreased range and stopping power. ![]() Service rifles with a longer barrel typically use larger calibre ammunition and have greater effective ranges and target effect. Initially used by horse cavalry and cannoneers, the carbine became the weapon for non-infantry soldiers and special units. The former are longer and employed by infantry, while the later are shorter. There is also a mention of novel lightweight ammunition, which hints at a capability to use the polymer-cased ammunition and the Lightweight Small Arms Technologies program being pursued by the Army.‘Long arms’ usually fall into two categories – the service rifle and the carbine. The rails must accept all current issue weapon lights and accessories, use the M27's heat-resistant rail covers, and come ready to field strip in manner similar to the M27 andīut even more interesting than the rail system is the list of secondary desired characteristics, including the ability to chamber a variety of calibers from the AB39 (7.62x51mm round optimized for long-range accuracy) and the Army's M80A1 round to two intermediate rounds: the. The RFI specifies a need for a continuous, uninterrupted 1913 Picatinny rail along the full length of the rifle, and while this can be semi-monolithic, the weapon must have anti-rotation features to stop movement. This year’s event follows 2016’s inaugural event, which Corps personnel praised as “the equivalent of Shot Show.”Īdditionally, the RFI suggests the Corps is looking for a lighter, more modern rail system compared to the current M27 Infantry Automatic Rifle. These events give the Corps a chance to explore its options and look at the industry’s latest developments without committing to a purchase - the procurement version of window-shopping. Other surfaces may include holes/cutouts for air circulation and weight reduction.Ĭompanies are invited to showcase their offerings at the annual Marksmanship Technology Demonstration that coincides with the Modern Day Marine conference in September.
