Since pistols and SBRs are the shortest AR configurations, something like the Boyt case suits your shorty. We chose the 10.3' Mk18 as an example, because lengths ranging from 9.5' to 11.5' tend to be the most common on conventional AR-15 pistols and SBR builds. The length of the barrel is determined by two factors, which will affect the overall length. This is because an AR pistol brace is designed to be used as a shooting rest, while an SBR stock is not. Likewise, AR pistol braces are typically larger than the rifle stock found on an SBR. The barrel length of pistols and SBRs can vary from 14.5' for M4 clone builds to 4.5' for pistol-caliber carbines. Overall height (with optic mounted to upper): 12.50'.Overall length (buttstock collapsed): 26.75'.This combination of features specifically makes it much better suited for close-quarters combat than other types. Additionally, it is also equipped with an aim point-type red dot sight that is approximately 3.75' tall. It has a 10.3' barrel and an A2 flash hider. This makes the AR-15 pistol a handy tool for close-quarters combat, as it is much more maneuverable than the rifle. The AR 15 pistol has become popular in the market, and its dimensions (and the choice of optics of the end user) tend to closely match the AR-15 short-barreled rifle. This case also features multiple locking points for added security, which can be locked with padlocks. It's also waterproof and includes a pressure equalization valve to ensure it remains sealed in any environment. With the stock collapsed, it'll fit any 16'-barreled AR with room to spare for red dots optics, ammo, handguard attachments, and accessories. It measures 36' long by 13.5' wide, with a 4.5' depth and plenty of padding for your rifle. The Boyt H-Series Hard Case would be a great choice to protect your firearm while in transit or storage. If you want to be able to keep your scope without having to remove it from the receiver, most 1' or 30mm scopes with scope rings installed on a flattop upper will measure around this height too.įor the AR 15 configured in the standard way, we would suggest using a 36' case that is 10' wide at the minimum to ensure optimal protection for your firearm. The Trijicon ACOG is 3.62' tall, and we think that using this as a measure for how wide your AR 15 should be is a safe and reliable guideline. Overall height (with optic mounted to upper): 12.25'.Overall height (receiver to end of magazine): 8.75'.Overall length (buttstock collapsed): 32.75'.The minimum length for the barrel of M16, by law, is 16' (which is 2' longer than the barrels of service-issued rifles).Īside from a 30-round magazine attached to the lower receiver and a Trijicon ACOG front sight equipped on top, the M16 also has the following dimensions: The M16 was first introduced in the 1960s and used by the US army ever since.Ī 20-inch barrel is an effective way to maintain velocity while ensuring the bullet is stabilized and supersonic for as much time as possible for accurate shooting. It is chambered for the 5.56x45mm NATO cartridge and can fire in both semi-automatic and three-round burst modes. The M16 is a gas-operated, semi-automatic rifle that uses a direct impingement gas operating system. All these features are standard on most military-grade rifles. This is This is considered a civilian mil-spec rifle, which means it comes with a forged pair of upper and lower receivers (where the barrel is attached), a mil-spec buffer tube, and A2-style flash hider, and a typical M4-type buttstock. Virtually all AR-15s sold in stores or bought by first-time owners are configured similar to what's shown above. We're breaking down the typical lengths and dimensions found on most AR-15s, so you can better select the one rifle case for you. Custom chassis and ultra-small buffers can vary in length compared with standard chassis configurations or super compact ones. This is a mil-spec configuration with standard lower components and tubes. You also have to contend with all the optics normally fitted on those flat-top uppers, even the occasional carry-handle receiver.įor our tests of new rifle pistols, we assume each uses a conventional receiver. AR-15s, or America’s rifle, come in a variety of configurations: modern M4 clones, the typical 16'-barreled rifle with an M4 buttstock, fixed-stock variants, pistols and SBRs, and long bench guns nominally chambered in either.
